Radiation Protection Group Member

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With a mission to uncover the fundamental structure of the universe, CERN employs thousands of scientists, engineers, and support staff from over 100 countries. The organization operates in multiple countries and is known for its cutting-edge research in particle physics, utilizing the world's largest and most complex scientific instruments to study fundamental particles and their interactions. Diversity is a core value at CERN, and the organization is committed to fostering an inclusive environment that reflects the diverse backgrounds of its workforce.

Job Overview:
The Radiation Protection (RP) Group within the Occupational Health and Safety and Environmental Protection (HSE) Unit at CERN is dedicated to ensuring the safety of personnel and the public from the harmful effects of ionizing radiation associated with CERN's activities. The selected candidate will join the HSE-RP-AS (Accelerators & Sites) section, which is responsible for all radiation protection aspects related to the design and operation of accelerators and experimental areas at CERN. This position offers a unique opportunity to gain hands-on experience in operational radiation protection, involving close collaboration with field operations and planning. The candidate will become proficient in using radiation monitoring instruments, conducting radiological risk assessments, and applying the ALARA (As Low As Reasonably Achievable) principle in practice. The role is primarily based at the Prévessin Site and encompasses the four Large Experiments at the Large Hadron Collider (LHC), namely ATLAS, CMS, LHCb, and ALICE.

Duties and Responsibilities:
The responsibilities of the Radiation Protection Group Member include performing radiation survey measurements to support team activities, becoming familiar with and utilizing CERN's computer tools, managing and handling radioactive materials, participating in the ALARA preparation and follow-up of activities in Radiation Areas, conducting measurements and radiation protection follow-up during the Long-Shutdown 3, and documenting results in detailed reports, technical notes, and other written documents. The candidate will also engage with interdisciplinary teams across CERN to ensure safe and efficient operations in radiation areas, contributing to the overall mission of protecting personnel and the public from radiation hazards.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and should have a maximum of two years of professional experience in Radiation Protection or a related field since graduation. The highest educational qualification required is either a Bachelor's or Master's degree. Applicants who have previously held a CERN fellow or graduate contract are not eligible, and those without a university degree or with a PhD are also ineligible for this position.

Educational Background:
The position requires candidates to possess either a Bachelor's or Master's degree in Radiation Protection or a related field. This educational background is essential to ensure that the candidate has the necessary theoretical knowledge and understanding of radiation hazards and safety protocols.

Experience:
The ideal candidate should have a maximum of two years of professional experience in Radiation Protection or a related field, which should be acquired after graduation. This experience is crucial for the candidate to effectively contribute to the responsibilities of the role and to engage with the various tasks associated with radiation safety at CERN.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the other language being highly desirable. Effective communication skills in both languages are essential for collaboration within the diverse teams at CERN.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, and the target start date for the position is April 1, 202

• The role involves working in Radiation Areas and may require interventions in underground installations. A valid driving license is necessary, and candidates should be aware of potential exposure to electromagnetic fields under certain conditions. Due to the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed. The job reference for this position is HSE-RP-AS-2025-177-GRAE.
