摘要

The design and performance of a new neutron dose equivalent meter or ''rem meter'' are described. Key design elements include a 6.38-inch diameter polyethylene moderator sphere loaded with Tungsten Carbide powder to 5% tungsten by weight, and a 2-mil thick cadmium foil located at a radius of 5 cm. A detailed response function for the new rem meter (dubbed the Model 652) was derived over the neutron energy range from thermal to 20 MeV using Monte Carlo transport techniques. Compared with the standard Eberline NRD rem mete, the new design is about 1.5 kg lighter, and is 28% more sensitive per unit dose of Cf-252. It is shown that for a large variety of standard and operational neutron spectra, the model 652 rem meter provides a response accuracy of (plus minus)15%.
