Radioanalysis & Instrumentation Specialist CERN 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.
Job Description Are you an expert in the domain of characterizing radionuclide inventories in components with radioanalytical and computational methods? Are you interested in joining a dynamic multi-national team of radiation protection specialists? Take responsibility for radiation protection of some of our installations and projects from A to Z at the world's largest particle accelerator complex and its experimental facilities.
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 the 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, and the legally required monitoring of the exposure of radiation workers to ionising radiation.
Functions As a Radiation Protection Physicist in the Characterization and Services Section (RP-CS), you will execute projects, studies, and services aimed at assessing radiological risks from activated materials and waste comprising their radiological characterization by determining nuclide inventories with measurements and simulations. In particular, you will:
Lead the RP radioanalytical laboratories activities, including the coordination of consolidation and upgrade measures as required for upcoming major accelerator shut-down activities;
Perform Radiation Protection research and development of novel measurement procedures for the radiological characterization of material and waste;
Improve or establish quality assurance procedures and protocols for various analysis techniques (gamma spectroscopy, alpha/beta counting, radiochemical analysis);
Produce, contribute to or edit legal, technical and scientific documentation, including rules, specifications, reports, notes, international publications, and presentations for CERN internal or external use;
Develop and maintain computational and mathematical models related to Monte Carlo particle transport simulations, including computer codes for predicting radionuclide inventories and their potential out-diffusion from solid objects;
Supervise or coordinate the work of technical personnel, post-docs, associates, and students.
Qualifications Master's degree or PhD or equivalent relevant experience in the field of radiation detection instrumentation & computational methods or a related field.
Radiation Protection Expert Certificate (accreditation according to Swiss or French legislation would be a plus).
Experience Extensive knowledge of Radiation Protection and the physics processes leading to the creation of radionuclides; demonstrated experience in the field of radiation measurements, in particular for radiological characterization purposes (gamma spectroscopy, alpha/beta counting); extensive experience in the use of Monte Carlo radiation transport codes, such as FLUKA (experience with deterministic codes related to radionuclide inventories such as ActiWiz, CINDER90 or FISPACT would be a plus); proven skills in writing technical and scientific documentation, including rules, reports, and international publications.
Technical competencies Knowledge and application of radioactive decay and spectroscopy
Knowledge and application of instrumentation and measurement techniques
Knowledge and application of statistical and numerical mathematical methods
Knowledge of programming techniques and languages
Knowledge of regulatory framework and best practice in radiation protection
Behavioural competencies Communicating Effectively
Working in Teams
Achieving Results
Learning and Sharing Knowledge
Language skills Spoken and written English: Ability to draw-up technical specifications and/or scientific reports and to make oral presentations in English. Ability to understand and speak French in professional contexts would be an advantage.
