“…The EPR technique is non destructive and has been widely used to estimate doses in radiological emergencies, as well as in therapeutics and in industrial processes with ionizing radiation. Several materials can be used as EPR dosimeters, for example alanine [5,6], hidroxyapatite (natural or synthesized), 2-methyl alanine, lithium formate, glucose, oxalates, phenols, etc [7][8][9][10][11][12][13][14][15][16]. The material of election depends on their dosimetric properties (sensitivity, time stability of the defects, linearity of the signal, etc) related to the specific application, and the dose interval of interest (ranging from some mGy to kGy).…”
