Abstract
Due to of deep penetration ability and strong secondary ionization, neutron-radiation is the mostly dangerous ionizing radiation for humans and environment. Developments in materials science provide neutron-sensor devices with enhanced selectivity and sensitivity. Among them, detectors based on boron-containing thin films are the naturally best because of special neutron-capture properties of 10B isotope. In this work, there are evaluated the key physical-technical characteristics of neutron detectors made from 10B-enriched semi-conducting materials: thickness of the effective working layer ~10 μm, releasing rate of the 10B – n interaction products ~1015/cm3 s, electron–hole pairs generating rate in process of neutron absorption ~1022/cm3 s, rate of rise in the temperature ~10 K/s, and device mean operating time ~10−4 s.
