Feasibility study of an active extremity dosimetry prototype
Résumé
In nuclear medicine departments, where radioactive sources are manipulated, the personnel can receive large radiation doses to the skin of their hands. For performing detailed characterisations and dose optimisations of these workplaces, active extremity dosemeters can be used as complementary tools to passive hand monitoring. Active extremity dosimetry is still a subject of research. In this context, IRSN has started a research and development programme. As a first step, a hospital workplace study has been performed using thermoluminescence dosemeters and has shown, in agreement with previous works, that the pads of the fingers, points that are very difficult to instrument, receive the largest doses. Numerical studies have now started, with the aim of calculating the dose equivalent gradients through the hands, in order to optimise the locations of the detectors.
