Anthropomorphic phantom for effective dose measurements : Feasibility numerical study and presentation of the detector development


Journal title : Radiation Measurements
Volume : 43
Issue : 2-6
Pagination : 590-593

Summary

The project presented here aims to create an expertise instrument for the workplace studies using an anthropomorphic dummy for the direct measurement of the effective dose. Contrary to other applications fields were anthropomorphic phantoms are generally used (radiotherapy dose control, aeronautics and spatial studies or accident dose reconstruction), the main challenge of this project is to develop small size detectors to be placed inside an equivalent tissue anthropomorphic dummy, sensitive enough to detect the low dose rates encountered at workplaces. A feasibility numerical study for photon irradiation fields has proved the interest of such an instrument and has determined the positions of the detectors for each organ. The results of this numerical study are presented in this article, as well as a preliminary schematic description of a prototype of the detector.
