The French post office located on the Prévessin site (building 866- R-C06) will close on 27 March 2026. This decision was taken by La Poste due to the operating costs of the office and its low level of use. Those wishing to send postal items may visit the post office in Prévessin-Moëns or the one
Following the Director-General’s approval on 17 December 2025, the revised Operational Circular No. 11, “The processing of personal data at CERN” (OC 11), entered into force on 1 February 2026. This revised Circular cancels and replaces Operational Circular No. 11 dated January 2019 and its two annexes which came into force on 1 July 2021.
On 12 January 2026, CERN’s Medical Service implemented KENORA, a new occupational health management system to modernise and strengthen occupational health monitoring across the Organization, replacing the existing KITRY (medical records) and PLAMED (planning tool). It is based on a single, secure platform and represents a significant step forward in the management of occupational health

Over the coming weeks, you may notice a vehicle equipped with antennas driving slowly on the CERN roads. This is part of the Non-Ionising Radiation Mapping and Assessment (NIRMA) project. The vehicle is equipped with the TURTLE (Top-mounted Unit for NIR Time-averaged Field Level Evaluation), a mobile unit dedicated to measuring electromagnetic fields in the

Safety is everyone’s responsibility. At CERN, pressure equipment such as vessels, piping and safety accessories is essential for both industrial and experimental activities. However, these systems also pose risks due to the energy they contain and the chemical hazards posed by their contents. In the interests of the safety of all personnel and installations, it

Following extensive audits by the French national organisation for standardisation (AFNOR) at the end of 2025, CERN’s ISO 50001 certification has been renewed for another three years, until 1 February 2029.
