2- OR 3-DIMENSIONAL DOSIMETER BASED ON A GEL- OR SOLID POLYMER-TYPE RADIOSENSITIVE MATERIAL MATRIX COMPRISING DIAMOND PARTICLES DISPERSED THEREIN

摘要

The invention relates to a dosimeter for detecting an ionising radiation, comprising a polymer matrix made of a radiosensitive material, in which particles capable of generating free radicals when exposed to the ionising radiation are dispersed, wherein the dosimeter is characterised in that said particles are diamond particles of submicrometer or nanometer size, and the surface of which has a negative electron affinity, preferably an aminated or hydrogenated surface. The invention also relates to a method for producing the dosimeter and a measurement method using the dosimeter.
