Research on atomic nuclei and radioactivity -

The atomic nucleus serves as the very core of each atom, comprising positively charged protons and electrically neutral neutrons. The atomic number, which is determined by the number of protons, ultimately defines the element in question. It is when the nucleus becomes unstable that we witness the phenomenon of radioactive decay. Through this process, unstable nuclei emit ionising radiation—manifesting as alpha, beta, or gamma particles—each possessing unique characteristics in terms of their ionising capabilities and penetrating power.

Radioactive decay leads to a transformation in the nucleus, resulting in the conversion of one element into another, a process known as nuclear transmutation. The rate of this decay is governed by a probabilistic rule, encapsulated in the concept of the half-life, which quantifies the time required for half of a given sample of radioactive material to undergo decay. Such a process is inherently statistical, with each individual nucleus exhibiting random behaviour, though large quantities of atoms permit predictions regarding the overall decay rate.

Detection of this radiation is accomplished through various means: for instance, the use of cloud chambers, which render visible the paths of charged particles; photographic plates, which darken upon exposure to radiation; or ionisation chambers, which detect the ionisation of air molecules caused by incoming radiation. The extent of radiation protection required varies based on the type of radiation: alpha particles, for example, can be stopped by a mere sheet of paper, while beta particles necessitate materials such as aluminium for shielding. Gamma rays, with their high penetration power, require more substantial shielding, often involving dense materials such as lead or thick concrete.

Radioactivity, though a natural phenomenon, also holds immense practical utility across various domains. In medicine, it aids in diagnostic imaging and targeted treatments, while in archaeology, it provides techniques such as carbon dating to determine the age of ancient artefacts. Furthermore, it is harnessed in the generation of energy through controlled nuclear fission. However, the inherent dangers posed by ionising radiation demand a rigorous understanding of radiological protection and safety, ensuring that human exposure is minimised.
