Modelling Radioactive Decay

The radioactive decay of atoms is a natural and basic nuclear phenomenon, which consists of the transformation of unstable atomic nuclei into more stable ones with the loss of particles or the emission of electromagnetic radiation. The goal of the study is to create a theoretical model that would help to comprehend what happens during the decay process and what factors influence it, as well as to define the circumstances in which the model would still be correct and predictive. By use of a literature analysis and mathematical modelling, the paper supports the exponential characteristic of the decay process, the additivity of decay constants at normal conditions, and half-life significance in the aspect of decay process determination. The results prove that the decay modelling is reliable not only in scientific but also in a practical way, starting with radiometric dating and ending with nuclear medicine.
