1. Radioactivity and the Nuclei of Atoms
... is used to kill bacteria and other microorganisms and sterilize medical devices. The Concept Half Life In theory, the decay process is never complete and there is always some residual radioactivity. For this reason, the half-life of a radioactive isotope is measured, rather than the total decay time. The time it takes for half the atoms in a given mass to divide (emit radiation and change to a stable ... released from the inner core, or nucleus, of the atom. Energy produced by nuclear fission (the splitting of uranium or plutonium nuclei) has been harnessed since the 1950s to generate e...
