Biological Dosimetry at the BfS

At the Federal Office for Radiation Protection (BfS) the national reference laboratory for biological dosimetry in Germany is located. Here dose estimations can be carried out on over-exposed or presumably over-exposed persons using biological indicators. The method used is a chromosome aberration analysis on lymphocytes of peripheral blood.

Biological dosimetry: procedure

Biological dosimetry following radiation exposure

Biological dosimetry is an internationally approved method to quantify the exposure and to perform a dose assessment following a suspected radiation overexposure. In contrast to physical methods, not the dose itself is recorded but the effects of the dose at the cellular level are investigated. Biological dosimetry takes into account the inter-individual variations in radiation sensitivity when assessing the effects of radiation in humans.
