Bacquerel , Bq, is the SI unit of activity for radioactive sources. It is equivalent to a count or disintegration per second. The activity is measured, typically, with a Geiger-Muller (GM) tube. | |
Beta decayor Where X is the parent nucleus, Y is the daughter nucleus, A is the number of nucleons and Z is the number of protons. An example decay is Properties of beta particles include

Binding energy is the energy required to assemble a nucleus or to separate the nucleus into its individual components/nucleons. (d) The binding energy per nucleon is the total binding energy for a particular nucleus divided by the number of nucleons contained in the nucleus. For energy to be released in a nuclear reaction, fusion or fission, the binding energy must increase. ![]() Image taken from http://www.smsec.com/en/nucl/07_1.htm | |
