Minimising ionising radiation

Members of the CERN environment team verifying a radiation monitoring station.

 

To study the composition of matter, CERN uses particle collisions that generate ionising radiation. CERN continuously monitors its ionising radiation levels to ensure that its releases to the environment are negligible. The vast majority of CERN’s radioactive materials are not contaminating and all radioactive materials are stored and handled following standard regulations. CERN adheres to the internationally accepted radiation protection system. Facilities and practices are continuously optimised to minimise radiological impact. With this system, the real radiological impact remains well below regulatory limits. All radioactivity measurements are regularly reported to the Swiss and French authorities.
