Operational Radiation Protection Technical Engineer in the Occupational Health and Safety and Environmental Protection Unit (HSE), Radiation Protection Group (RP), Accelerators and Sites Section (AS).

You will join:

The Occupational Health and Safety and Environmental Protection (HSE) Unit, which acts, on behalf of the Director General, in matters of safety and the protection of personnel and environment. The Radiation Protection Group protects workers and public against the risks of exposure to ionising radiation, ensuring that exposure is kept as low as reasonably achievable. The duties of CERN's Radiation Protection Group include the assessment of radiation hazards of CERN's activities, including new accelerators and experiments, the definition of protective measures as well as the legally required monitoring of the exposure of radiation workers to ionising radiation.


As Operational Radiation Protection Technical Engineer, you will: 

  • Assess radiological risks at work places in accelerator tunnels, experimental areas, laboratories and workshops of CERN.
  • Perform radiation measurements in various static radiation fields as well as in dynamic high-energy multi-particle type radiation fields.
  • Evaluate, analyse and process dosimetry data.
  • Evaluate, analyse and process data from gamma spectroscopy, beta and alpha analysis and liquid scintillation counting.
  • Draw up safety measures and working procedures; perform job and dose planning; advice personnel working in radioactive laboratories and other radiation areas on radiation protection matters.
  • Prepare radioactive goods for transport and off-site shipping according to international rules for the transport of dangerous goods.
  • Prepare written reports on a regular basis.
