Method of measuring fast neutron flux using thermoluminescent dosimeter

摘要: Thermoluminescent phosphors which are susceptible to neutron activation exposed a mixed field of radiation. Thermoluminescence resulting from prompt gamma irradiation is removed by short period annealing at high temperature. The then stored in shielded chamber maintained sufficiently low temperature allow accumulation radiation dose produced radionuclides formed on activation. thermoluminescence attributable this self-irradiation read and correlated flux or dose. Through use separate phosphor materials having different threshold energies for activation, energy spectra fast obtained.
