Neutron Dosimetry Using a Tissue-Equivalent Ionization Chamber.
Abstract
A system for the measurement of neutron tissue does or kerma has been assembled and tested. The dosimeter is a tissue-equivalent ionization chamber, of modified commercial design. It is enclosed in an airtight aluminum shell, which can be filled with tissue-equivalent gas and sealed, thereby eliminating the need for continuous gas flow. Ionization current can be measured using either a commercial electrometer or a DREO-constructed electrometer. The latter instrument enables the readout device to be located far from the dosimeter without an increase in the leakage current. Calibration theory and procedures are described, and correction factors discussed. (Author)
