[Radioprotection in radiology, a controversial practice: how to wear the individual dosimeters?].
After a short recall of the Belgian legislation in the field of radiation protection, the practical organization of individual dosimetry is described. The workers occupationally exposed to radiation shall always wear an individual dosimeter at the level of the chest. When a high irradiation of the hands is suspected, it is necessary to wear a second dosimeter at the level of the wrist or the fingers. When a lead apron is used, due to the important resulting dose heterogeneity, two dosimeters have to be worn, the first one permanently at the level of the chest (behind the lead apron), the second one at the level of the non-protected parts of the body (e.g. neck, shoulders). The effective dose is then calculated by adding the dose received by the first dosimeter and the dose received by the second dosimeter (not shielded by the lead apron) divided by a weighting factor of 10. This evaluation of the effective dose is fully conservative.
