Radiation Protection Technical Engineer

European Organization for Nuclear Research (CERN)

Job Description


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

Job Description


Are you passionate about your job as a Radiation Engineer" id="link" class="link">Protection Technical Engineer? Would you like to participate in a dynamic multi-national team of radiation protection specialists? Contribute your skills and expertise in radiation protection to the world's largest particle accelerator complex and its experimental facilities. CERN, take part!

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 and radioactive waste management.


As a Radiation Protection Technical Engineer in the RP Characterization & Services Section (RP-CS) you will:

  • Be responsible for all legal and technical aspects related to transport of radioactive material

  • Apply dose-rate, gamma-spectrometry and contamination measurements as well as in-house developed computational tools to classify radioactive transports

  • Coordinate a small team of technicians

  • Perform, coordinate and validate measurements in the radioanalytical laboratory (gamma-spectrometry, alpha/beta counting, liquid scintillation counting)

  • Provide advice on various legal aspects related to transport and shipping

  • Prepare written reports on a regular basis.


Bachelor's degree or equivalent relevant experience in the field of radiation protection and transport of radioactive material or a related field.


  • Extended experience in the transport and shipping of radioactive items under international ADR regulations

  • Demonstrated experience in analytical laboratory measurements, especially in gamma spectroscopy, liquid scintillation measurements and alpha/beta counting;

  • Practical knowledge in operational Radiation Protection (handling of sources, Radiation Protection instrumentation);

Technical competencies:

  • Transport of dangerous goods: (ADR class 7 certification required; IATA certificate would be an asset)

  • Knowledge and application of ionizing radiation: (gamma spectroscopy, alpha/beta counting, liquid scintillation counting measurements)

  • Knowledge and application of radioactive decay and spectroscopy

  • Quality Management

  • Knowledge of regulatory framework and best practice in radiation protection

Behavioural competencies:

  • Achieving Results: delivering prompt and efficient service taking into account customer needs Having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind
