BI OR THREE-DIMENSIONAL DOSIMETER WITH RADIOSENSITIVE MATERIAL OF GEL TYPE OR SOLID POLYMER FILLED WITH DIAMOND PARTICLES AND ASSOCIATED PROCESSES

摘要

The invention relates to a dosimeter for the detection of ionizing radiation, comprising a polymer matrix made of a radiosensitive material, in which particles capable of producing free radicals when exposed to ionizing radiation are dispersed, the dosimeter being characterized by that said particles are diamond particles having a submicrometric or nanometric size and the surface of which has a negative electronic affinity, preferably a hydrogenated or aminated surface. The invention also relates to a method of manufacturing this dosimeter, as well as a measurement method using this dosimeter.
