Abstract
An electron paramagnetic resonance device includes a crystalline, emission-sensitive mass and a housing containing the device. The mass includes structurally incorporated carbonate content in a range of about 3% by weight to about 10% by weight of the mass, one or more structurally incorporated non-calcium metallic cations, and one or more structurally incorporated phosphate anions. When irradiated with a known source, the EPR device may function as a reference. When unirradiated, the EPR may function as a dosimeter. As a dosimeter, the EPR device may be used as a personal dosimeter or as a monitor for inanimate objects being subjected to radiation sources. The EPR dosimeter may be used for both gamma radiation and neutron radiation measurements.
