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.

Search the Glossary by either clicking on a letter or typing a keyword into the search box. This glossary is relational so when looking at one term you can click through to other related terms as required.

For formal advice, see our Radiation Protection Adviser pages. 

Biological Dosimetry

Biological dosimetry is a branch of the field of Dosimetry which uses biological samples, usually taken from individuals who have been exposed to radioactive materials, as a means to assess intakes by Inhalation and Ingestion. For example analysis of urine can be used to assess Tritium uptake whilst analysis of faecal matter can be used to determine Actinide uptake. Biological sampling can also be used to assess direct body Irradiation from External Radiation hazards.

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
