Radiation Protection Glossary

A radiation protection glossary for Radiation Protection Supervisors (RPS), Radiation Protection Advisers (RPA) and anyone else interesting in radiation safety terms and definitions. The glossary is a mixture of health physics , phrases related to radiation protection legislation, transport, practical safety, technical terms and similar.

Decay Product

A radionuclide produced as a result of a parent radionuclide's decay. The decay products may be derived from their immediate predecessor, of through several other decays in a decay chain series. One example would be Radon Decay products where Ra-222 will decay to products including Polonium 218 (via alpha decay) and then Lead-214 (also alpha decay).

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less
