We would like to inform you that there is a change in the medical follow up of category B (annual dose < 6 mSv/year) employed members of the CERN personnel (MPE) and associated members of the personnel for the purpose of training (MPA-t: doctoral, technical and administrative students or trainees) who are working in CERN Radiation Areas. 

Following a recommendation by the International Commission on Radiological Protection (ICRP), medical surveillance related to occupational exposure to ionizing radiation it is no longer required for category B radiation workers under European law (Directive Euratom 2013/59) and in Switzerland (decision of Swiss National Accident Insurance Fund, SUVA, of July 2016).  

CERN has decided to follow this trend and to discontinue, medical surveillance related to occupational exposure to ionizing radiation of all category B workers among its MPE and MPA-t population (cf. memorandum [EDMS 2088793]). 

As CERN workers, they will, of course, continue to be subject to medical surveillance by CERN’s Medical Service in accordance with the CERN Staff Rules and Regulations and the CERN Safety rules.

For information, medical surveillance of associated members of the personnel (other than MPA-ts) remains the responsibility of their employer.
