Radiation Protection Physicist (HSE-RP-AS-2019-80-LD)

  • Geneva, Switzerland
  • 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


Are you interested in joining a dynamic multi-national team of radiation protection specialists? Take responsibility for radiation protection of installations and projects of 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 in matters of safety and the protection of personnel and environment. The Radiation Protection (RP) 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 RP Group include the assessment of radiation hazards of CERN’s activities, encompassing 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 a Radiation Protection Physicist in the RP-AS Section, you will monitor and enforce compliance with Radiation Protection regulations and execute projects, studies and services aimed at protecting people and the environment from the ionising radiation generated by CERN's activities. In particular, you will:

  • Lead and take responsibility for Radiation Protection (RP) risk assessments and for the definition of protective measures.
  • Provide expertise to CERN's departments and management on radiation protection aspects of the design, operation and maintenance of accelerators and experiments.
  • Lead or participate in RP research and development, in particular the development, use and maintenance of models, computer codes, state-of-the-art tools, instruments and methods for radiological risk assessments.
  • Produce, contribute to, or edit legal, technical and scientific documentation, including rules, specifications, reports, notes, international publications and presentations for internal and external use.
  • Supervise or coordinate the work of technical personnel, fellows, associates and students.


Master's degree or PhD, or equivalent relevant experience in the field of physics or nuclear engineering with a specialization in radiation protection, or a related field.


  • Demonstrated experience in operational radiation protection at high-energy accelerators and experiments.
  • Demonstrated experience in radiation protection in the design of high-energy accelerators and experiments.
  • Proven experience in the use of Monte Carlo radiation transport codes, such as FLUKA.
  • Proven experience in writing technical and scientific documentation, including rules, reports and international publications.

Technical competencies:

  • Study of radiation protection design: i.e. expertise in radiation protection design studies.
  • Knowledge of regulatory framework and best practice in radiation protection: i.e. knowledge of radiation exposure and operational radiation protection.
  • Simulation of radiation environments: i.e. calculation of activation and dose rates around high-energy accelerators.
  • Knowledge and application of instrumentation and measurement techniques: i.e. knowledge of measurement techniques for ionising radiation.
  • Knowledge of regulatory framework and best practice in radiation protection: i.e. knowledge of national radiation protection legislation and/or relevant European regulations.

Behavioural competencies:

  • Working in teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
  • 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.
  • Communicating effectively: ensuring that information, procedures and decisions are appropriately documented; providing others with timely information; selecting the appropriate medium and forum to communicate.
  • Learning and sharing knowledge: keeping up-to-date with developments in own field of expertise and readily absorbing new information; sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer; proposing ways to improve or streamline existing procedures, processes and methodologies.

Language skills:

  • English: spoken and written, with the ability to draw-up technical specifications and/or scientific reports and/or to make oral presentations. 
  • Ability to understand French or an undertaking to acquire it rapidly.
