Workstation studies: estimate the dose received by your staff

The employer has three main duties:

1. conduct a predictive assessment of collective and individual doses that workers are likely to receive during dosing operations;
2. define limits for collective and individual doses for the operations concerned;
3. measure and analyse the actual radiation doses received during the operations and compare them to the predicted doses.

The exposure risk analysis can be complemented by an analysis of other risks at this workstation.

The Radiation Safety Officer is generally responsible for these measurements and analysis, which he should record such as in an exposure or risk analysis sheet .  He also recommends the P.P.E. (personal protective equipment) and C.P.E. (collective protective equipment) suitable to the workstation.

The exposure sheet enables the classification of the exposed workers into Class A or B.

The delimitation of controlled areas enables the selection of ambient dosimeters and individual dosimeters required and adapted to access these areas.

The workstation study is part of the ALARA policy of the company, as it allows mapping of the most dosing operations and improvement of operational protocols (implementation of personal protective equipment or collective protective equipment, reduction of exposure time, etc.)

It must be performed in realistic conditions of the workstation, i.e. in locations more likely to be occupied by workers.
