Proposed Calibration Factors for Various Dosimeters at Different Energies

Abstract

In order to permit a quicker and, in most cases, more accurate assessment of dose it is proposed that dosimeters, or dose-ratemeters, be calibrated and designed to follow the variations in dose absorbed in critical organs at various photon energies. The proposed calibration factors are based on measurements made on a realistic phantom. They apply to photons in the energy range 0.03–1.5 MeV. Five different kinds of dosimeter are considered: hand-held gamma-survey meters, area gamma-monitors, dosimeters carried on the person, gamma-survey meters for use in disaster situations and environmental gamma-monitors.
