Neutron kerma coefficients of compounds for shielding and dosimetry

摘要

Alloys, concretes, glasses, neutron shielding material, polymers, nuclear track detectors, are being used for shielding and dosimetry applications. The neutron kerma coefficients of eighteen compounds have been calculated for neutrons energy less than 30 MeV; these compounds are used as shielding and dosi-metric materials. The kerma coefficients are found lowest for all the compounds in intermediate energy (10 eV＜E＜ 10 keV). The neutron kerma coefficients are higher for the compounds containing large weight fraction of low-Z elements. A resonance in neutron kerma coefficient is observed for the large amount of oxygen containing compounds. It is found that at high energies kerma coefficients are approximately same, but very large differences for energy less than 100 eV.
