WebAlpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. An alpha particle is identical to the nucleus of a helium-4 atom, which consists of …

WebTypical beta emitters include strontium 90, technetium 99, caesium-137, carbon-14, sulfur-35, and tritium.

WebFor other energy ranges, see Wang, p 912. [5] Values are from Y. Wang (reference). Another rule-of-thumb is that the half-value range is approximately 1/7 of the maximum range but may vary between 1/5 and 1/10 (depending on beta energy and absorber density). [6] The mass absorption coefficient also depends on the energy of the radiation.

WebSome of these high-energy beta emitters can be used as nuclear therapy sources (such as Yttrium-90), or as tracers in nuclear medicine (e.g. P-32).
