Mesures radiologiques de terrain, évaluations dosimétriques, conseils réglementaires et assistance technique — l'ARSN met son expertise au service des opérateurs, des autorités et du public.
ARSN offers a comprehensive range of technical services to licensed operators, government authorities and medical establishments.
Carrying out on-site radiological measurements: dose rates, surface contamination, radiological mapping of facilities and their environment.
Assessment and interpretation of doses received by workers exposed to ionising radiation: external dosimetry, internal dosimetry, dose reconstruction.
Radiological analysis of environmental or industrial samples: gamma spectrometry, alpha/beta activity measurement, analysis of water, soil, air and foodstuffs.
Assistance with preparing authorisation files, interpretation of regulations, optimisation of radiation shielding (ALARA) and compliance support.
Radiation protection training sessions for workers, managers and first responders. Practical workshops with measuring instruments on site.
ARSN has a fleet of modern measuring instruments, regularly calibrated and verified, to ensure reliable and traceable measurements.
Measurement of ambient dose rate H*(10) in µSv/h or mSv/h in the field. Energy from 15 keV to 10 MeV.
Identification and quantification of gamma-emitting radionuclides in samples or in the field.
Measurement of radon-222 concentration in indoor air, mine galleries and outdoor. Continuous or instantaneous measurement.
Detection and measurement of alpha and beta surface contamination in Bq/cm². Monitoring of persons, premises and equipment.
High-resolution gamma spectrometry for precise identification of radionuclides in complex matrices (water, soil, food).
Thermoluminescent (TLD) and electronic dosimeters for individual dose monitoring of exposed workers.
The request for technical support from ARSN follows a simple and quick procedure to guarantee a response in the shortest possible time.
Contact the Radiation Protection Directorate by mail, email or in person. Describe the type of support required, the context and urgency.
An ARSN expert contacts you to precisely define the scope of support, the intervention date and the necessary preliminary information.
The ARSN technical team carries out on-site measurements or analyses your samples in the laboratory. A preliminary report is communicated at the end.
ARSN provides you with an official report with quantified results, their regulatory interpretation and recommendations for actions to implement.
ARSN's technical support is open to any institution or company with radiation protection needs, whether or not it holds an authorisation.
Quality control of radiological equipment, dosimetry of medical personnel, training of medical physicists, assistance with authorisation files.
Surveillance radiologique des sites miniers (SOMAÏR, IMOURAREN), mesure du radon en galerie, cartographie des résidus, évaluation de la dose des mineurs.
Contrôle des sources scellées industrielles, vérification des blindages, audit de radioprotection, formation des opérateurs, conseils en optimisation ALARA.
Conseil technique aux ministères, évaluation radiologique de projets d'infrastructure, expertise dans le cadre de procédures judiciaires ou administratives.
Support for radiation protection research projects, training of medical physics students, provision of expertise for scientific publications.
Reassurance radiological measurements after reporting of a suspicious source, neutral scientific information, awareness in mining areas.
All ARSN technical support is guided by the ALARA principle (As Low As Reasonably Achievable): exposures to ionising radiation must be kept as low as reasonably achievable, taking into account economic and social constraints.
Contact ARSN's Radiation Protection Directorate to formulate your request. Our experts will respond within 48 working hours.
