Application of track detectors in personnel neutron dosimetry

A survey is presented of the use of track detectors with emitters of fission fragments and alpha particles and without emitters for the measurement of neutron doses, and the advantages of this system are emphasized. The results are given of a study of the best dosimetric system (radiation sources Th; Th+0.5%Usub(nat); U enriched to 6.5% + detectors Melinex 9 μm and Makrofol KG 10 μm) for the optimal track counting method (spark counter). The dosimetric properties of the system, e.g. fading, dose and energy dependence etc., were determined. A dosimetric badge and an etching device were developed to serve personal dosimetry. (author)
