The European Commission's Directorate-General for Energy, in particular the health protection sector of the Radiation Protection and Nuclear Safety Unit, is responsible for the radiation protection of staff members. Therefore, it shall arrange that every classified staff member is equipped with an appropriate passive individual radiation dosimeter and, for staff working with beta-emitters, an individual finger dosimeter. Additionally, the health protection sector is responsible for environmental monitoring in the radiation protection and instrument calibration laboratories. This necessitates monitoring ambient radiation exposures for gamma, beta and neutron radiation. The relevant dosimeters shall be periodically distributed and analysed. The results of the subsequent estimation of the personal equivalent doses shall be recorded and reported to the health protection sector monthly.

The individual radiation dosimeters shall be appropriate for the expected typical radiation environment inside nuclear fuel cycle installations. They should monitor mixed fields of gamma, beta and neutron radiations.

The estimation of the individual personal dose equivalent values Hp(10) and Hp(0,07) shall be based on the parameters given by the Council Directive 96/29/Euratom (Basic Safety Standards Directive) as well as of the 2007 recommendations of the ICRP specified in the publication 103.

Up to 250 passive personal dosimeters and up to 10 personal finger dosimeters are to be supplied and analysed each month. In addition, 20 dosimeters for measuring ambient radiation exposures H* for gamma, beta and neutron radiation are to be delivered and analysed monthly. Each monthly delivery shall comprise dosimeters dedicated for radiation background determination and subtraction.
