Determination of Absorbed Doses in the Radiation Fields of a Neutron Generator

A method for determining doses absorbed by biological objects on irradiation with neutrons from portable generators with energies of about 14.1 MeV was developed. The contributions of each of the components of the radiation field to the total dose were analyzed and introduced errors were assessed, permitting irradiation schemes to be optimized. Determination of dose from the intensity of neutron release from the target, despite a rather large introduced error, is quicker and more convenient than direct measurement with a dosimeter.
