摘要
Abstract
Neutron personal dose monitoring is an important part of external monitoring for occupational exposure.According to the principles of neutron detecting of CR39 and its structure,experiments regarding energy response and angle response as well as dose equivalent response of CR39 neutron personal dosimeter against neutron flux emitted by Am-Be were conducted.Results show a strong dependence of neutron flux sensitivity on the energy and incident angle of neutron.The critical angle of 64° for incident neutron and neutron flux sensitivity of about 2.24×10-4 trs/n were obtained.关键词
