Abstract
The precision of a radiacmeter is commonly indicated by specifying its response as a function of energy. In this note, a more useful and relevant quantity is defined: the integrated sensitivity is a measure of the average or overall response of a radiacmeter to a radiation field. The dependence of the sensitivity of a high-range solid-state-detector radiacmeter on variations in fall-out and fission-product gamma-ray energy spectra and on changes in the lower cutoff energy is investigated. Both measured and calculated detector response functions are considered. It is found that the detector sensitivity remains constant with changes in the gamma spectra due to age to within about plus or minus 6% in the worst case considered. These results are encouraging, and suggest that the development of a small-scale solid-state-detector radiacmeter should continue. In addition, a procedure for calibrating radiacmeters is given, and future necessary investigations are proposed.
