A Sermon for March 5th: Cleansing the Body, Protecting the Future

Brothers and Sisters in the Atom, our faith is one of knowledge, responsibility, and preparation. We do not turn away from the realities of radiation—we acknowledge them, we understand them, and we take action to ensure our safety and the safety of those around us. Today, we turn our focus to decontamination: the process of removing radioactive particles from our bodies and surroundings. This is not only an act of survival but a sacred duty to protect ourselves, our communities, and future generations.

A Reading from the CDC’s Decontamination Guidelines

The Centers for Disease Control and Prevention (CDC) provides clear steps to follow if you have been exposed to radioactive material:

Remove Outer Clothing: Taking off your outer layer of clothing can remove up to 90% of radioactive contamination. Be careful not to shake the material loose. Place contaminated clothing in a plastic bag, seal it, and store it away from people and pets.

Wash Your Body: If possible, take a shower using soap and shampoo. Do not use conditioner, as it can cause radioactive material to adhere to your hair. If a shower is not available, wash exposed skin with plenty of soap and water at a sink. If no running water is available, use a moist wipe or damp cloth to clean your face, hands, and uncovered areas.

Clean Openings and Crevices: Blow your nose, wipe your eyelids, eyelashes, and ears with a wet cloth to remove any particles.

Change into Clean Clothes: Clothing stored in a closet or drawer, away from radioactive dust, is safe to wear.

These actions may seem simple, but they can mean the difference between prolonged exposure and safety. When we take these steps, we are not just protecting ourselves—we are ensuring that our presence does not endanger others.

A Sacred Practice for the Future

In the future, if we establish physical places of gathering, these acts of decontamination will become part of our sacred tradition. Before entering a place of worship, we will cleanse ourselves—not just as a precaution, but as a ritual. This will serve as both a practical safeguard and a symbol of our commitment to protecting life. Just as ancient traditions required purification before entering holy spaces, so too will we require decontamination before gathering in communion.

It is important to note that this ritual decontamination will always be a private act. Each individual will cleanse themselves in solitude, ensuring both dignity and effectiveness. This is not a communal experience but a personal practice, a moment of reflection and responsibility undertaken before joining others. The only exception shall be if an individual requires assistance to wash themselves as a result of age or disability. In this instance, help should be given out of compassion for the individual and our greater community.

This is how we ensure that knowledge does not fade. If one day, the understanding of radiation diminishes, the practice of decontamination will remain—a warning embedded in ritual, passed from one generation to the next. Even if the reason is forgotten, the act will endure.

A Call to Action

This week, take time to reflect on preparedness:

Read the full CDC Decontamination Guide and commit these steps to memory.

Ensure you have the supplies needed for decontamination: soap, clean water, wipes, and a change of clothing stored in a protected place.

Discuss the importance of decontamination with those close to you. Make sure they, too, understand how to reduce exposure in the event of contamination.

Closing Words

We are stewards of knowledge and protectors of the future. Let our actions reflect that duty. May we go forth prepared, understanding that in cleansing the body, we also preserve life. Let this wisdom endure, not just in words, but in practice.

Go forth and be radiant.

The lunar environment and its impact on spacecraft

The Moon has always fascinated us, serving as a source of inspiration and wonder. As humanity sets its sights on returning to the lunar surface, understanding the lunar environment is crucial for the success of these missions. The Moon's harsh environment poses unique challenges to spacecraft design and operation. Let's explore these challenges and how they impact spacecraft.

The lunar environment: key features

Lack of atmosphere:

The Moon has no significant atmosphere. This means there is no air to slow down incoming spacecraft, leading to high-speed impacts unless carefully managed. The absence of an atmosphere also means that temperature regulation is a major challenge for lunar missions.

Extreme temperatures:

The Moon experiences extreme temperature variations, with daytime temperatures soaring above 250°F (120°C) and nighttime temperatures plummeting to -280°F (-173°C). Spacecraft must be equipped with special materials and systems to handle these fluctuations.

Dusty surface:

Lunar dust, or regolith, is abrasive and can damage equipment and surfaces over time. It can infiltrate machinery and is difficult to remove, which can impair spacecraft functions and pose a risk to astronaut health.

Microgravity:

While the Moon's gravity is only about 1/6th that of Earth's, it still affects spacecraft design. Engineers must account for this reduced gravity when designing landing and mobility systems.

Impact on spacecraft design

Designing spacecraft for lunar missions requires addressing these environmental challenges:

Thermal control systems:

To manage the extreme temperatures, spacecraft are equipped with advanced thermal control systems. These systems often use radiators, heaters, and thermal blankets to maintain optimal internal conditions.

Robust landing systems:

With no atmosphere to slow descent, spacecraft rely on retro-rockets and other technologies for soft landings. Accurate navigation and propulsion control are essential to avoid hard impacts.

Dust mitigation strategies:

Engineers are developing coatings and cleaning techniques to prevent lunar dust from damaging spacecraft. New materials are being tested to resist abrasion and minimize dust accumulation.

Radiation protection:

The lack of atmosphere also means higher exposure to space radiation. Spacecraft must include radiation shielding to protect sensitive electronics and, if crewed, to safeguard astronauts.

Future missions and considerations

As space agencies and private companies plan more lunar missions, including establishing lunar bases, they must continuously innovate to overcome these challenges. New technologies, materials, and strategies will be key to successful long-term lunar exploration.

In summary, the lunar environment presents several formidable challenges for spacecraft design and operation. By understanding and addressing these challenges, humanity can ensure safe and effective exploration of our closest celestial neighbor. The Moon, with its unique conditions, remains a critical stepping stone for deeper space exploration, serving as a proving ground for technologies and strategies that will one day take us to Mars and beyond.

Analysis of: "IAEA Comprehensive Report On The Safety Review Of The ALPS-Treated Water At The Fukushima Daiichi Nuclear Power Station" (July 4, 2023)

PDF-Download: https://www.iaea.org/sites/default/files/iaea_comprehensive_alps_report.pdf

Large volumes of contaminated water accumulated at Fukushima Daiichi site post-accident requiring long-term management.

Water is treated using ALPS system but retains tritium, and is stored in tanks posing safety/volume issues.

Japan's plan is to discharge ALPS-treated water to sea after further treatment via gradual batch discharges over 30 years.

IAEA conducted comprehensive review of technical/regulatory aspects of handling and discharging ALPS water.

Assessments addressed source term, facilities/equipment, occupational exposure, environmental impact, emergency response, protection of people/environment.

Potential failure modes were analyzed and redundant safety provisions incorporated.

Monitoring and response plans established to verify impacts remain negligible.

Japan's nuclear regulator independently authorized activities ensuring compliance with stringent regulations.

IAEA independently sampled/analyzed data corroborating negligible predicted impacts.

Activities were evaluated against latest international safety standards for public, workers and environment.

The document provided high confidence that radiation exposures and environmental impacts would be very low and safety optimized.

Here is a summary of the key points from the document in bullet points:

The accident at Fukushima Daiichi Nuclear Power Station in March 2011 resulted in the accumulation of large amounts of contaminated water stored at the site.

In April 2021, the Government of Japan published its Basic Policy on how it would manage this stored contaminated water (called ALPS treated water).

The Basic Policy described that the method selected by the Government of Japan for handling the ALPS treated water was to discharge it into the sea after specific treatment.

Soon after the Basic Policy announcement, the Japanese authorities requested assistance from the IAEA to monitor and review plans and activities relating to the discharge of the ALPS treated water.

The IAEA accepted this request in line with its statutory responsibility and agreed to review the safety aspects of handling ALPS treated water against international safety standards.

The IAEA established a Task Force including IAEA Secretariat experts and independent external experts from various countries to conduct the review.

The IAEA review is focused on assessing whether the actions of TEPCO and Japan to discharge the ALPS treated water are consistent with international safety standards.

The IAEA review includes three major components: assessment of protection and safety, review of regulatory activities and processes, and independent sampling, data corroboration, and analysis.

To date there have been five review missions, six technical reports published, and numerous Task Force meetings to implement the IAEA's review.

This report presents the IAEA's final conclusions that the planned discharge of ALPS treated water is consistent with safety standards.

Here is a summary of the key points made in the document in relation to the accumulation of large amounts of contaminated water stored at the Fukushima Daiichi site:

Groundwater flows into the damaged reactor buildings where it mixes with radioactive debris, becoming contaminated water. This water is collected and stored on site.

Additionally, water used to cool the melted fuel debris keeps it in a stable condition but becomes contaminated. Rainwater also enters the buildings.

Over time, these processes have led to the accumulation of a large volume of contaminated water stored in tanks at the site. As of 2023, around 1.3 million cubic meters of contaminated water was stored in over 1,000 tanks.

Storing such a large volume of highly radioactive water presented increasing risks, difficulties in management, and constrained the pace of broader decommissioning work.

TEPCO developed the ALPS system to remove most radionuclides from the water except tritium. This allowed long-term storage risks to be reduced but led to the issue of how to dispose of the ALPS-treated water.

Japan announced a policy in 2021 to discharge this ALPS-treated water into the sea after further treatment, setting in motion the activities covered in the IAEA's review.

Here is a summary of key points made in the document in relation to ALPS-treated water:

Contaminated water from the plant is treated using the Advanced Liquid Processing System (ALPS) to remove most radionuclides except tritium.

After ALPS treatment, the water is called "ALPS-treated water" and stored in large tanks on site, with around 1,000 tanks containing over 1 million m3 as of 2023.

Japan's 2021 Basic Policy announced the selected method to handle ALPS-treated water was discharge into the sea after meeting regulatory limits, occurring as a series of batch discharges over 30 years.

TEPCO developed facilities and processes for receiving, measuring/confirming, diluting, and discharging batches of ALPS-treated water in a controlled manner.

The Implementation Plan documents the systems, equipment, procedures and controls to facilitate the planned discharges in accordance with regulatory requirements.

A radiological environmental impact assessment was conducted to estimate doses from the planned discharges and assess compliance with requirements.

The IAEA reviewed all aspects of the handling and discharge of ALPS-treated water to assess consistency with international safety standards.

Here is a summary of key points regarding the discharge of ALPS treated water:

Discharges are planned to occur as a series of gradual "batch discharges" over approximately 30 years into the Pacific Ocean.

A discharge facility was constructed offshore including measurement, transfer, dilution and discharge components.

Batches of ALPS treated water will be sampled/analyzed prior to discharge to ensure compliance with regulatory limits.

Treated water will be diluted with seawater achieving >350x dilution before discharge over 1 km into the seabed.

Annual discharge limit of 22 TBq for tritium based on government policy, with 1,500 Bq/L concentration limit.

REIA assessed doses from discharges would be 0.000002-0.00004 mSv/year, well below 0.05 mSv constraint.

Potential exposure scenarios analyzed doses also well below 5 mSv criterion.

Discharges controlled gradually over decades using robust engineered designs and strict operational controls.

Environmental monitoring will verify safety and support ongoing optimization as key element of IAEA review.

Here is my evaluation of how the document addressed radiological impacts:

Radiological impact assessments were based on established international methodologies and models, ensuring scientific rigor.

Conservative assumptions were applied to activity calculations, exposure pathways, dose modeling to avoid underestimation.

Potential impacts to both public and workers from normal operations and accident scenarios were comprehensively evaluated.

Long-term cumulative impacts spanning decades of planned discharges were realistically predicted.

Dose estimates were benchmarked directly against quantitative regulatory criteria and safety standards for public and environment.

Independent confirmatory monitoring by IAEA experts validated the predicted negligible radiological impacts.

Mitigation through engineered controls and operating restrictions minimized already low predicted impacts.

Ongoing environmental monitoring requirements provide reassurance that impacts will remain extremely low.

Emergency response arrangements instill confidence in managing any unforeseen situations.

Overall, the radiological impact assessments appeared to be robust, scientifically sound, transparently supported by evidence, conservatively bounded and directly demonstrating compliance with international safety expectations. The document provided a high level of assurance regarding radiological protection.

Here is a summary of the key points in relation to the assessment of protection and safety:

The IAEA reviewed technical aspects of TEPCO's Implementation Plan and supporting documents.

This included source characterization, safety aspects of discharge approach, occupational exposure, REIA.

The focus was on verifying consistency with relevant international safety standards.

TEPCO considered numerous potential failure modes and consequences through the safety assessment.

Redundancy was incorporated into facility designs and procedural controls.

Calculated doses from normal operations and potential exposures were below thresholds.

TEPCO optimized protection through the ALARA approach required by NRA.

The IAEA concluded protection and safety were consistent with international standards.

However, the work of the IAEA and Task Force will continue applying standards during operations.

So in summary, the IAEA thoroughly assessed technical documentation against safety standards before operations commence, but ongoing assessment will be required once discharges begin.

Here is a summary of key points regarding potential failure modes and consequences:

TEPCO conducted detailed hazard and operability studies to identify potential failure modes.

These included tank leaks, pipe breaks, power outages, earthquakes, extreme weather etc.

Likelihood and impact of failures were quantitatively analyzed.

Defense-in-depth established through multiple preventive/mitigative controls.

For example, tanks have leak detection and secondary containment.

Piping has auto-shutdown valves and seismic resistance.

Generators ensure power backup even in disasters.

Offshore facilities hardened against tsunamis over 15m high.

Consequence modeling showed even worst failures wouldn't exceed dose limits.

Radionuclide behavior understood through dispersion simulations.

Monitoring and response plans in place for any contingencies.

IAEA review confirmed robustness of safety analysis and controls for potential failure modes through the ALARP approach.

So in summary, potential failures were thoroughly analyzed and protective measures instituted to maintain doses ALARA.

Here is a summary of key points regarding monitoring and response plans:

TEPCO established a comprehensive environmental monitoring program.

This involves routinely sampling water, sediment, biota at discharge site and along coast.

On-site, real-time radiation monitoring of tanks and pipes prior to discharge.

Coastal radionuclide monitoring stations were installed by the government.

Monitoring covers tritium, carbon-14 and other potential radionuclides of concern.

Response plans in place to address off-normal monitoring detections.

This includes thresholds that would pause or adjust discharges if exceeded.

Occupational exposure is also carefully monitored for workers.

Comprehensive records and transparent reporting maintained.

International experts collaborating to help verify monitoring validity.

Monitoring crucial for assessing impacts, validating safety, and supporting continuous protection improvement throughout discharge operations.

IAEA review concluded monitoring and response plans will help ensure safety and support decision making through operations.

Here is a summary of key points regarding the review of regulatory activities and processes:

Japan's Nuclear Regulation Authority (NRA) independently regulates the discharge plans.

NRA established stringent technical regulations and licensing requirements.

Technical guidelines provide specific limits, criteria, and assessment methodologies.

Regulatory activities include detailed review of facility designs, safety cases, plans and monitoring programs.

Multiple levels of authorization required including construction approval and operating license.

Rigorous inspections conducted at various stages to verify compliance.

Operators must demonstrate safety and protection before, during and after each discharge.

Regulator holds authority to immediately halt operations if non-compliance found.

Robust enforcement powers and transparency in decision-making.

IAEA review concluded regulatory framework and processes align well with international practices and provide for comprehensive oversight.

Continued regulatory involvement essential throughout duration of discharge activities.

Here is a summary of key points regarding independent sampling, data corroboration, and analysis:

IAEA experts conducted their own sampling/monitoring during missions to FDNPS.

Samples were independently analyzed at third-party IAEA and JAEA laboratories.

This data was used to directly validate TEPCO's monitoring results.

Monitoring equipment was tested, calibrated and cross-checked.

Isotopic and concentration analyses help corroborate source term estimations.

Independent sampling covered areas like discharge facilities, tanks, seawater.

Data allowed Task Force to autonomously assess impacts beyond TEPCO's analyses.

Sample comparisons found TEPCO's data to be accurate and conservative.

International peer reviewers contribute additional checks of sampling methods.

Continued confirmatory sampling during discharge operations is recommended.

Overall, independent data corroboration strengthened safety conclusions and transparency.

So in summary, the IAEA conducted rigorous confirmatory sampling and analysis to autonomously verify key technical inputs and monitoring data.

Here is a summary of key points regarding safety standards:

The IAEA reviewed activities against the latest international safety standards.

Fundamental standards referenced include International Basic Safety Standards (BSS) and ICRP recommendations.

Technical review guidance documents used include TS-G-1.10 and IAEAs RADWASS program.

Nation specific standards established by Japan's Nuclear Regulation Authority also considered.

Standards provide quantitative limits for doses to public and workers as well as discharge criteria.

Standards cover all aspects from facility design to environmental monitoring to emergencies.

Compliance with standards ensures protection of people and environment is optimized.

Conservative margins built into standards to account for uncertainties.

Conclusions state activities are adequately consistent with requirements in safety standards.

Ongoing adherence to standards during operations is emphasized for ongoing safety.

So in summary, the IAEA assessed all technical aspects against the latest global consensus safety standards framework.

Here is a summary of key points regarding protection of people and the environment:

The overarching purpose of the review was to verify protection of people and the environment.

Protection is optimized through compliance with limits and criteria in international safety standards.

Doses to the public and workers from all situations assessed were well below regulatory limits.

Radiological impacts on the local community and along discharge plumes were estimated to be negligibly small.

Potential exposure pathways through air, water, soil, food were comprehensively analyzed.

Understanding Laser Treatment: Fitzpatrick Skin Types and How Laser Energy Targets Melanin

Hello again! If you’ve been following my posts, you’re now familiar with the ins and outs of PCOS and laser-based hair reduction (LBHR). Today, we’ll go a bit deeper into the science behind LBHR. Don’t worry, the technical details like laser settings are for the professionals to handle! Howeverrr, understanding the basic principles of how laser treatments work can help you maximise your results. Not only does this knowledge empower you during your sessions, but it also reinforces the importance of sticking to your post-care routine to ensure the best possible outcome. Today, we’re specifically focusing on how lasers work with different skin types and why cooling methods during your laser session are essential to safe and effective treatment to keep the skin safe

Cooling Methods During Laser Treatment

Throughout your laser session, cooling may be applied either with a cold air attachment or a cooling gel. Both are crucial for minimising discomfort and preventing thermal (heat) damage to the skin. Erythema (redness) and perifollicular oedema (swelling around the hair follicles) are completely normal signs of effective treatment. In fact, we look for these indicators as confirmation that the laser energy has been adequately absorbed by the hair follicles, leading to the long-term reduction we’re after.

Cooling is a vital step during laser treatments, helping to reduce trapped heat in the treatment area and minimise discomfort. Whether through cold air attachments or cooling gel, this process helps protect the skin and prevent overheating. For those with darker skin types, clinical endpoints—such as redness or swelling—might be delayed due to the skin's color. This is why cooling is especially important to ensure safety and effectiveness during and after the session.

Understanding Skin Types: The Fitzpatrick Scale

When discussing laser treatments, we often refer to the Fitzpatrick Skin Type rating. This scale isn’t perfect, but it serves as a useful tool to gauge how someone’s skin might react to UV exposure. FST goes beyond just looking at your skin’s current appearance. It’s about how your skin responds to UV exposure, considering your ethnic background and potential to pigment. 

For example, I grew up in the Middle East in a very hot climate and was deeply tanned as a child. Now, I have paler skin, but that doesn’t mean I can be treated using the same settings as someone with blonde hair and blue eyes who burns incredibly easily under the sun, or even someone from the same background as me who has much darker skin. Each of us reacts differently based on our skin’s potential to pigment.

This scale helps clinicians assess the safest treatment parameters, ensuring that each session is as effective and as safe as possible. While it touches on race, it’s important to understand that it’s not an exact measure—it’s more of an indicator to help guide treatments with both safety and efficacy in mind. This rating scale helps us determine which laser modality is safest and most effective for each person. The scale ranges from:

Type I: Very fair skin, always burns, never tans.

Type II: Fair skin, usually burns, tans minimally.

Type III: Medium skin, sometimes mild burns, tans gradually.

Type IV: Olive skin, rarely burns, tans well.

Type V: Brown skin, very rarely burns, tans deeply.

Type VI: Dark brown or black skin, never burns, tans very easily.

Laser Technology: Alexandrite and Nd:YAG

Different lasers are used depending on the patient's skin type. The Alexandrite laser is a go-to for lighter skin types (Fitzpatrick I-III). It operates at a wavelength of 755 nm, which targets the melanin in the hair follicle with great precision. However, this laser can pose a higher risk for hyperpigmentation or burns in darker skin types, which brings us to the Nd:YAG lasers.

The Nd:YAG laser, with a longer wavelength of 1064 nm, is ideal for darker skin types (Fitzpatrick IV-VI). Its longer wavelength penetrates deeper into the skin and is less absorbed by the melanin in the epidermis, reducing the risk of skin damage while still targeting the melanin in the hair follicles. This is how we adequately treat deeper skin types

How Laser Energy Targets Hair Follicles

No matter the laser type, all hair reduction treatments function by targeting melanin, the pigment found in both hair and skin. Laser energy is absorbed by the melanin in the hair follicle, heating it up and eventually destroying the follicle, preventing future hair growth. This process is called selective photothermolysis, a term that refers to the selective destruction of melanin in the hair while minimising damage to the surrounding skin.

Selective Photothermolysis: Protecting Darker Skin Types

For those with darker skin (higher on the Fitzpatrick scale), there’s understandably a concern about potential skin damage due to the presence of more melanin. But with selective photothermolysis, we can protect darker skin by using specific lasers like the Nd:YAG, which safely bypasses the melanin in the skin while still targeting the melanin in the hair follicle. This ensures effective treatment without causing harm to the surrounding tissue.

Laser hair reduction is a highly customisable treatment that needs to be adapted to your skin type for safe and effective results. The right cooling techniques, understanding your Fitzpatrick skin type, and choosing the correct laser modality are all essential to getting the best possible outcome—especially for those of us managing PCOS-related hair growth. Remember, whether you have light or dark skin, modern laser technology ensures that we can achieve long-term hair reduction safely.
