Practical guide. Realisation of dosimetric studies for workplaces exhibiting a ionizing radiation exposure risk (version 4)

This guide proposes a methodological approach to help carry out dosimetric workplace studies complying with the French regulation, and necessary to identify risks of radiological exposure, optimize radiation protection and classify the workers into different categories. Additional information is provided relating the main objectives of a workplace study, the French regulatory context, main sources and pathways of exposure to ionizing radiation. Radiation protection and operational quantities are reminded. Recommendations about the selection and use of detectors and about the implementation of calculation methods are also provided. The general methodological approach is applied and developed into 'workplace sheets', each one devoted to a particular type of workplace. Up to now only sheets related to medical field have been developed. By extension, advices for classify the workplaces into different areas are also supplied. (authors)
