<h3><u>Explanation;</u></h3>
The half-life of a radioisotope is the amount of time it takes for<em><u> half the sample to decay. </u></em>
- <em><u>Radioactive particles or nuclides undergoes the process called radioactivity </u></em>which is the spontaneous decay of radioactive materials to emit radiation such as beta particle, alpha particle and also associated with energy loss.
- <em><u>Half-life is the time taken by a radioactive substance or material to decay by half of the original isotope to decay.</u></em> For instance; <em><u>when the half life of 100 g of substance X is 5 years, this means that after five years only 50 g of the substance would remain.</u></em>
