Detection and Measurement of Radioactivity,Radioactivity is the spontaneous decay of unstable nuclei and as we have seen this is usually accompanied by the emission of charged particles or photons. The more important forms of radioactive decay are collected in ., where the emissions associated with the different decay processes are indicated.
