METHOD FOR EVALUATION OF NEUTRON MODERATING POWER VARIATION DUE TO THE GAMMA-RAY EXPOSURE OF HIGH DENSITY POLYETHYLENE

摘要

A kind of method, it is arranged to improve accuracy since the gamma ray of high density polyethylene (HDPE) is exposed in actual analysis of experimental data for evaluating moderation of neutrons capacity variation, by mitigating structure to the analysis in terms of element content product as molecular structure makees a neutron. A kind of method, with different range of exposures dosage irradiation gamma rays to a neutron, mitigates structure for evaluating moderation of neutrons capacity variation since the gamma ray exposure of high density polyethylene (HDPE) includes: a first order; Experimentally measure neutron a second step by using for structure a neutron beam source and a neutron detector, wherein gamma ray is illuminated; One third step of the assessment moderation of neutrons capacity variation of HDPE (high density polyethylene (HDPE)) neutron mitigates structure, by the analysis in terms of element content product as molecular structure makees structure.
