The European Commission employs a number of staff classified as exposed to ionising radiation in the course of their work. Under European and national radiation protection law, the European Commission as an employer is obliged to establish a system for monitoring the radiation exposure and to assess the individual radiation doses of each classified staff member. This assessment shall include both radiation doses due to external exposure as well as doses due to intakes of radioactive substances.

This call for tender, launched by the Health Protection Sector of the European Commission Directorate-General for Energy, invites analytical laboratories, institutes or research centres to submit offers for the radio-toxicological analysis of bioassay samples. In cases where it is necessary, from the radiation protection point of view, the potential contractor shall be in a position to estimate the internal radiation doses expressed as 50 years' committed effective dose. For these specific dose assessments, the European Commission's occupational medical health service and the Health Protection Sector will provide the potential contractor with indispensable additional information and data.
