Conversion and Quality Factors Relating Neutron Fluence and Dosimetric Quantities

Abstract

Values of conversion factors between neutron fluence and various dosimetric quantities, compiled and derived from recent data, are given as a function of neutron energy. These quantities include the kerma, dose equivalent and quality factor for small volume elements, the maximum dose and dose equivalent in a 30 cm diameter cylindrical tissue phantom, and the dose and dose equivalent at 1 cm depth in 30 cm cylindrical and spherical phantoms. Values for different phantoms are compared with one another and with the ICRP's effective dose equivalent. Empirical analytical expressions are given for the energy variation of some of these conversion factors.
