There are several areas in the natural world where the process of exponential decay arises from random processes. Whenever a material decays at a rate in proportion to its amount, this material represents the process of exponential decay. Exponential decay can be described using the mathematical model y=a×e^(-bx). A prominent example of naturally occurring random exponential decay is the process of radioactive decay. Some isotopes of nature are considered radioactive due to a specific characteristic of their nucleus. Radioactive isotopes, or radioisotopes, do not contain the proper amount of neutrons. As a result of this, the nucleus of radioisotopes is unstable. The instability causes them to emit particles or electromagnetic waves from
