The purpose of the present study is developing a new dosimeter detector based on biological hydroxyapatite having several advantages over the existing analogs, and methods of its application. Properties of the biological materials were studied by continuous and pulsed EPR in order to determine their suitability for application as dosimetric materials. Possible differences in the mechanisms of formation of radiation-induced stable free radicals in the biological hydroxyapatite of different origin were considered, and radiation sensitivity of this materials was determined. Studies were also aimed at finding a binder having the properties of neutrality to radiation and biocompatibility. A test batch of artificial radiation detectors based on the chosen material, epoxy resin, was produced and tested. Detectors were tested for their usefulness in the calibration of artificial radiation beams as well as for radioecological studies
