Question

How decay is related to the half-life of a radioisotope?

Answer 1

Radioisotopes are radioactive isotopes of a component. They can likewise be characterized as atoms that contain an unstable mixture of neutrons and protons, or an abundance of energy in their nucleus. The unstable nucleus of a radioisotope can happen normally, or because of artificially changing the molecule. Sometimes, an atomic reactor is utilized to deliver radioisotopes, in others, a cyclotron. Atomic reactors are most appropriate for delivering neutron-rich radioisotopes.

Complete step-by-step answer:
Radioactive decay is the deterioration of an unstable molecule with a going emanation of radiation. As a radioisotope particle decays to a steadier molecule, it transmits radiation just a single time. To transform from a flimsy particle to a totally steady molecule may require a few deterioration steps and radiation will be emitted at each progression. However, when the molecule arrives at a steady configuration, no more radiation is emitted. Therefore, radioactive sources become more fragile with time. As an ever increasing number of unstable particles become stable atoms, less radiation is delivered and ultimately, the material will get non-radioactive.

The decay of radioactive components happens at a fixed rate. The half-life of a radioisotope is the time needed for one portion of the measure of unstable material to degrade into a more steady material. For instance, a source will have a power of $100\%$ when new. At one half-life, its power will be sliced to half of the first intensity. At two half-lives, it will have a power of $25\%$ of another source. After ten half-lives, less than one-thousandth of the first action will remain. In spite of the fact that the half-life configuration is the equivalent for each radioisotope, the length of a half-life is extraordinary for each one. For instance, $Co - 60$ has a half-life of around $5$ years while $Ir - 192$ has a half-life of around $74$ days.

Note: Molecules with an unstable nucleus recapture security by shedding excess particles and energy as radiation. The way of shedding the radiation is called radioactive decay. The radioactive decay measure for every radioisotope is special and is estimated with a time span called a half-life. One half-life is the time it takes for half of the unstable molecules to go through radioactive decay.
