Realisation of dosimetric studies for workplaces with a risk of exposure to ionizing radiations (version 2). Practical guide

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, classify the workers into different categories and the workplaces into different areas. 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. (authors)
