Radiation Protection Technician (HSE-RP-AS-2023-108-LD)

  • Contract

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Job Description


With about 50 km of accelerator infrastructure and over 160 high energy and nuclear physics experiments CERN is home to the world-wide largest network of Radiation Areas. Are you passionate about your job as a Radiation Protection Technician? Would you like to participate in a dynamic multi-national team of radiation protection specialists? Contribute your skills and expertise to radiation protection at the world's largest particle accelerator complex. Take Part!

The Radiation Protection (RP) Group of the Occupational Health and Safety and Environmental Protection (HSE) Unit ensures that personnel on the CERN sites and the public are protected from potentially harmful effects of ionizing radiation linked to CERN activities. The duties of CERN’s Radiation Protection Group include the assessment of radiation hazards from operating accelerators and experiments, the definition of protective measures as well as the legally required monitoring of the exposure of radiation workers and public to ionising radiation.


As a Radiation Protection Technician in the RP Accelerator and Sites Section (RP-AS) you will:

  • Assess radiological risks at workplaces in accelerator tunnels, experimental areas, laboratories, storage areas and workshops of CERN, elaborate dose prevention and dose minimisation measures, including the radiological characterisation of potentially radioactive materials and waste.  
  • Perform radiation measurements in various, static and dynamic high energy, multi-particle radiation fields.
  • Perform work and dose planning and elaborate protection measures as well as work procedures.
  • Evaluate, analyse, and follow up operational dosimetry data.
  • Contribute to the drafting and updating of radiation protection documents and procedures.
  • Advise personnel on radiation protection matters.
