Electromagnetic Radiation (EMR) and Its Effects

In recent years there has been considerable discussion and concern about the possible hazards of electromagnetic radiation (EMR), including both RF (Radio Frequency) energy and power frequency (50-60 Hz) electromagnetic fields.

All life on Earth has adapted to survive in an environment of weak, natural low-frequency electromagnetic fields (in addition to the Earth's static geomagnetic field). Natural low-frequency EM fields come from two main sources: the sun and thunderstorm activity. But in the last 100 years, man-made fields at much higher intensities and with a very different spectral distribution have altered this natural EM background in ways that are not yet fully understood. It has been known since the early days of radio that RF energy can cause interference in most of the wireless operated systems and in devices which process extremely low power signals associated with control systems and in medical equipments. Very high density of Electromagnetic Fields have been known to have resulted in injuries by heating body tissue. These heat-related health hazards are called thermal effects. In addition, there is evidence that magnetic fields may produce biological effects at energy levels too low to cause body heating. The proposition that these thermal effects may produce harmful health consequences has produced a great deal of research. Human body nervous system is also known to work on extremely low intensities of electrical signals. Very little has been done to investigate the effect of Electromagnetic Fields on the human nervous and control system which as such leaves a lot of scope for future research.

Potential Sources of EMR

The list could be endless starting with seemingly harmless AC (alternating current) operating devices to all the intentional and non- intentional transmitters. Appreciable radiation occurs as the size of the components and connecting wires approaches one tenth of the wavelength of the operating frequency. The intensity of the field so radiated also depends on the power handled by the device. To name a few tube lights, spark plugs, washing machines, music systems, power amplifiers, computers, lifts, air conditioners, cable TV, computer screen etc all fall in the category of non-intentional transmitters but can be potential source of Electromagnetic Radiations. All radio and TV broadcasting systems, telecommunication systems and equipments, RADARS, mobile phones etc are intentional transmitters of Electromagnetic Radiations and may result in typical effects on various systems in addition to causing serious interference problems and affecting human body.

With ever increasing use of modern digital technology in almost all the modern processing and communication equipments the threat of unintentional Electromagnetic Radiation is further enhanced. As all digital signals positively have a very large bandwidth, its increasing use will result in Electromagnetic Radiations in almost all the frequency ranges there by leaving a possibility of affecting most of electronic devices and also human beings.

Some Typical Effects of EMR

Electromagnetic Interference: Interference is the energy levels introduced by electronic or communications systems that have a detrimental effect on other systems. Any electronic system is capable of receiving Electromagnetic Radiations if the size of the components or connecting wires approaches one tenth of frequency that may be present in the surrounding environment due to any intentional or unintentional transmitter. Depending on the intensity of this unwanted received radiation there could be instances of malfunctioning of the device receiving this energy. There have been number of instances where such a condition had resulted in catastrophic failure of the equipments. The most famous example is the failure of the Electronic surveillance system installed at one of the ships of United Kingdom Naval forces during Falkland war due to operation of its own Radar system installed on the same warship. As a result of this only one system could be operated at one time resulting in the loss of the ship. Intentional Jamming of the radio receivers by the security and police forces is the utilization of this effect to make the enemies receivers inoperative, however it can also happen due to unwanted and unintentional Radiation of Electromagnetic fields.

Effects on Human Body: Body tissues that are subjected to very high levels of RF energy may suffer serious heat damage. These effects depend upon the frequency of the energy, the power density of the RF field that strikes the body, and even on factors such as the polarization of the wave.

However, additional longitudinal resonances occur at about 1 GHz near the body surface.

Health Care Engineering: Is electromagnetic Interference (EMI) becoming a problem in the healthcare environment? Although electrical interference in hospitals is often regarded as no more than a minor nuisance, there are documented cases in which equipment failures due to Electromagnetic Interference (EMI) have lead to injury or death. Some examples fare as follows: -

o In 1992, a patient attached to a monitor-defibrillator in an ambulance died because of interference from the ambulance radio prevented the machine from working (1).

o In 1987, patient monitoring systems failed to sound alarms because of interference; two patients died as a result (2).

o In 1993, a patient fitted with a pacemaker went into ventricular fibrillation shortly after being scanned with a metal detector outside a courtroom (2).

As in many other fields, the amount and complexity of electronics in hospitals and other medical environments is increasing year by year. Despite this, the number of reported incidents of EMC (Electromagnetic Compatibility) problems fortunately does not appear to be growing. This is probably because most manufacturers and designers of medical electronic products have developed a good awareness of EMC. Pacemakers are typical examples, where their design with respect to compactness and immunity to radio frequency interference has greatly improved over the years. Nowadays, pacemakers are very reliable, but can still fail under extreme conditions. Pacemakers have failed in patients undergoing electro surgery (2) and in other cases where patients kept mobile phones in their chest pockets, a few centimeters from the pacemaker leads (3). The powered Wheelchair is another typical example: there are many stories of radio frequency interference. (RFI) from mobile phones or police 'walkie-talkies' causing the wheelchair to drive itself and its occupant into traffic. These stories are based on real occurrences; reports of incidents in the USA in the early 1990s prompted the Food and Drug Administration (FDA) to investigate the problem and recommend that the manufacturer change the design to give an immunity of at least 20V/m to RFI.

What You Need to Know About Electromagnetic Radiation

What is electromagnetic radiation?

There are several different types of radiation present in our surroundings on a day to day basis. Within the electromagnetic spectrum, radiation is either ionizing or non-ionizing. Ionizing radiation is harmful to humans, because exposure causes cells and genetic matter to mutate or change form. Non-ionizing radiation, while it has believed to be safe, is now proven to overheat cells, causing them damage as well. Electromagnetic radiation (EMR) can be described in terms of a stream of photons, which are massless particles each traveling in a wave-like pattern and moving at the speed of light. Electromagnetic radiation (EMR) is often called an electromagnetic field (EMF) when it falls within the lower frequencies. Electromagnetic radiation includes gamma radiation, X rays, ultraviolet radiation, visible radiation, infrared radiation, radar, and radio waves. Electromagnetic energy is emitted, or given off, by all matter in our universe at varying levels.

So, how do the energies and frequencies of our high-tech world affect our subtle energy field, the blueprint for the physical body? First, virtually every single electrical appliance, computer, electric wire, and especially high voltage lines produce electromagnetic fields, called EMFs. The problem is that EMFs are disruptive to our body's own natural energy field. When the electromagnetic energies, coupled with all the frequencies from microwaves, TVs, satellites, etc., penetrates the human energy field, they disrupt it, damage it, and interfere with its normal functioning. There is also an extreme low frequency radiation (ELF) that is emitted from military installations, industrial machines, microwave transmission systems, high voltage power lines, and dozens of other sources. In fact, we live in a virtual fish bowl of radiation; a chaos of random photon bombardment which affects every living cell of the human body.

What are the health effects of exposure to electromagnetic radiation?

Electromagnetic radiation adversely affects organic life at the molecular, cellular, biochemical and physiological levels. We are bombarded by low levels of radiation from all directions. For example, did you know that the following give off radiation emissions? Hair dryers, cell phones, power lines, transformers, and clock radios. Exposure to EMFs causes tissue damage by releasing electrons in the cells, called ionization. Some of the possible health complications from long-term exposure to low level radiation include digestive problems such as abdominal pain, constipation, and diarrhea; and can possibly alter and mutate DNA. Additional EMF signs of over exposure include drowsiness, chronic aches and pains, sleep disorders, irritability, loss of energy, and may eventually lead to more serious diseases such as cancer and autoimmune system deficiency.

EMR may also disrupt the critical balance and wreak havoc with the millions of electrical impulses that the body uses to regulate all cellular activity. As cell phones, microwaves, satellites and radio have all become much more widespread; people claim to suffer everything from headaches to cancer as a result of their exposure to this so-called "harmless" radiation. Today, there are up to four billion cell phone users being exposed every day to the dangers of electromagnetic radiation. In fact, numerous studies have shown that cell phone towers may cause headaches, cancer, tumors, fatigue, and sleep problems.

In addition, EMR can potentially distort and disrupt the cellular communication signals resulting in abnormal cellular metabolism and consequently illness. Hundreds of other studies on the negative effects of electromagnetic radiation to the immune system, enzyme synthesis, nervous system, learning, mood and behavioral pattern have been proven to be consistent and statistically significant. In animal studies, exposure to cell phone radiation for as little as two minutes is proven to have a damaging effect on the brain and blood vessels.

With the enormous increase of electromagnetic and radio wave radiation, increasing numbers of illnesses such as allergies, fatigue, asthma, heart disease, brain cancer, depression, and sleep disorders are on the rise. It normally takes about a decade for cancer to rear its ugly head, so the effects of EMR could very well be a disaster in the making.
