Abstract
The calibration method discussed in this paper is based on a conceptual relationship between personal dose equivalent and neutron-induced alpha particle tracks and/or neutron-induced recoiled tracks on the polycarbonate detector when used as a part of polymeric personal albedo neutron dosimeter. The relationship represents personal dose equivalent as a function of track density of the second-order polynomial form. The parameters of the calibration relationship were optimized by fitting low detectable track density up to highest possible track density of which a significant part consisted of non-resolvable overlapped tracks, as seen by a scanning system. Our personal albedo neutron dosimeter was irradiated on a standard rectangular cubic water phantom using 252Cf and 241Am-Be reference neutron sources and the effect of scattered neutrons on the detector response was corrected by employing an analytical method, which is discussed in this paper.
