Prevention Assistants

Prevention Assistants (PAs)

They assist and advise the unit manager.

They work in liaison with the IRPS of the DR12 of the CNRS, the HST engineers of the AMU campuses, and the prevention physicians of the AMU and the CNRS.

They provide advice and assistance in the implementation of safety and prevention measures.

They make agents aware of the need to comply with safety instructions and rules and participate in their training.

They inform newcomers of the provisions of the internal regulations, the particular risks encountered in the unit and good practices to prevent them and participate in their training.

They ensure that the unit's occupational health and safety register is properly maintained.

They learn from accidents and incidents that have occurred in the unit.

They ensure that first aid is provided in the event of an accident.

The Competent Persons in Radiation Protection (PCR)

CEREGE has 7 X-ray generators (Pasteur and Trocadero buildings), 2 particle accelerators (ASTER and MICADAS), a sealed radioactive source (OSL, ASTER building) and unsealed radioactive sources (Pasteur building, rooms 158, 104 and waste storage room 101).

Since 2013, the radiation protection related to these installations emitting ionizing radiation has been carried out by two persons competent in radiation protection (PCR): Abel Guihou and Perrine Chaurand, appointed by the CEREGE Director. The two PCRs collectively carry out radiation protection missions, but given the specialities of the training modules followed, Abel Guihou manages more specifically unsealed sources and Perrine Chaurand deals more specifically with X-ray generators, sealed sources and particle accelerators.

PCRs must be informed before any proposed purchase/installation of new installations emitting ionizing radiation.  Any accidents, incidents, theft, anomaly or displacement of the installations must be reported to the PCR.

The PCRs ensure that radiation protection rules are in place.

Their missions are diverse:

    Delimitation of regulated areas

The PCRs carry out risk assessment, advise the unit manager on the delimitation of regulated areas (radiological zoning based on the zoning by-law and the labour code), give their opinions on the definition of access rules and safety instructions, signal radiation sources and propose and implement collective and/or individual prevention/protection measures.

    Analysis of workstations

The PCRs carry out a preliminary risk assessment for exposed personnel, carry out a provisional dosimetric assessment (exposure sheet for each worker), define collective and individual dose objectives and propose a possible classification of exposed workers.

    Training of exposed personnel

PCRs organize and participate in radiation protection training for exposed personnel.  Managers and regular users of facilities and unsealed sources are trained in radiation protection every 3 years (training conducted by an external organization).

    Administrative follow-up

PCRs ensure compliance with regulations (French standards) and ensure regulatory monitoring. They participate in the preparation of the declaration or authorisation files with the ASN, notify the ASN of any changes to the files and notify it of any significant events in radiation protection.

The PCRs ensure the monitoring and management of sources by sending an annual inventory to IRSN.

The PCRs are responsible for waste management and relations with ANDRA.

    Regulatory radiation protection controls

The PCRs define the programme of internal and external controls in an internal document, carry out annual internal controls (technical controls of installations, protection and signalling devices, measuring and environmental devices) and schedule annual external technical controls carried out by an approved body.

    Dosimetry management

Individual monitoring of staff exposure by passive dosimetry is implemented under the responsibility of the headteacher by the RCPs.  PCRs provide technical management of dosimetry. The occupational physician monitors the results of the name dosimeters. The CEREGE PCRs are alerted by the doctor of any abnormal results.

Management of degraded situations

PCR shall take measures to stop the causes of the exceeding of the dose limits, shall study the circumstances and assess the doses received by workers, and shall take the necessary measures to ensure that the situation does not recur.
