Neutron dosimetry at workplaces of JC “Institute of Nuclear Materials”

If the neutron fields at personnel workplaces differ from in which individual dosimeters are verified, there is a possibility of additional errors assessment such dosimetric quantities as ambient dose equivalent, equivalent or effective dose. To take into account energy distribution radiation flux density and geometry irradiation workers, it necessary to study characteristics personnel. In order obtain conditionally true levels exposure nuclear facilities, studies angular were carried out Institute Reactor Materials JSC, Zarechny. The was obtained using an MKS-AT1117M multi-sphere dosimeter-radiometer with BDKN-06 detection unit set polyethylene spheres-moderators. estimated results measurements accumulated by thermoluminescent placed on four vertical planes heterogeneous human phantom. made possible estimate values equivalents. calculated conventionally measured 0.7 8.9 times for 6 50 equivalent. reduce error assessing personal dosimeters, correction factors determined. For different types range 0.02 0.16.
