Irradiation of food - A food safety process that uses radiation to kill germs that can cause food poisoning (foodborne illness)., Gamma decay - Is the emission of very high energy electromagnetic waves after alpha or beta decay occur., Nuclear fission - Is the process of splitting a heavy atom into lighter atoms causing a chain reaction., Nuclear weapon - Is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion reactions, producing a nuclear explosion., Nuclear fusion - Is the process in which two light atoms join to forma heavier atom., Beta decay - Is when the nucleus transforms one neutron into a proton (increasing Z) and emits an electron (beta particle)., Exothermic reaction - A reaction that releases energy as heat or light., Radiometric dating - An application of radioactivity in which by knowing the rate of decay the age of rocks and fossils can be determined., Radiation therapy - Is the use of radioactivity to treat certain cancers., Alpha decay  - Is when the nucleus emits positively charged particles (2 protons and 2 neutrons), Scintigraphy - Is a method to examine the body by taking radioisotopes internally., Nuclear power plant - Is a electrical plant that produces electricity by moving a turbine with steam produced by fission reactions., Radioactive decay - Phenomenon in which the nucleus of an unstable isotope spontaneously emits subatomic particles and energy.,
