Biological Dosimetry at the BfS

In the cytogenetic laboratory of the BfS in Neuherberg, 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.

Approved Laboratories for Incorporation Monitoring (ALIM)

Approved Laboratories for Incorporation Monitoring (ALIM)

In Germany the accredited laboratories (ALIM) are responsible for the monitoring of incorporations within the framework of physical radiation protection control. These laboratories apply the monitoring methods usual for the assessment of the body dose in case of internal radiation exposure

Measurement methods

Measurements of radiation exposures from Radon-222 can be performed using either passive measurement devices or direct-reading devices. Passive measurement devices include radon diffusion chambers equipped with nuclear track detectors, providing readings proportional to the radiation imparted by radon during the period of measurement. These measurement devices are particularly suitable for long-term studies covering several months. Direct-reading devices should be used to measure the current radon concentration and to study its variation with time.

Radon Calibrating Laboratory

The Federal Office for Radiation Protection (BfS) operates an accredited calibration service laboratory for quality assurance of radon and radon progeny measurements. The laboratory offers calibration, type tests and comparison tests for measurement devices. Besides, it carries out scientific investigations on the metrological background, evaluation and improvement of measuring methods. The Radon Calibration Laboratory is accredited by the German Accreditation Body (DAkkS). It maintains a quality management system and is assessed regularly.

ProZES

The software ProZES will be a tool for experts in claims for compensation of radiation-induced occupational diseases. It calculates the probability that cancer in a specific person was caused by previous occupational radiation exposure. A trial version of ProZES can already be downloaded.
