Abstract The capabilities of electret ion chambers (EICs) to measure mean ambient dose equivalent rates were investigated by performing both laboratory and field studies their properties. First, EICs ‘calibrated’ gamma in the Ionizing Calibration Laboratory Greek Atomic Energy Commission. irradiated with different photon energies from angles. factors deduced (electret’s voltage drop due irradiation terms equivalent). In studies, installed at eight locations belonging Early Warning System Network (which is based on Reuter-Stokes ionization chambers) for three periods, averaging 5 months each. same locations, situ spectrometry measurements performed portable germanium detectors. Gamma soil sample analysis. daily potential (in Volts) was compared equivalent, measured a HPGe detector high-pressure chambers. From these measurements, ‘field’ calibration radiation equivalent) found very good agreement values Laboratory. influence cosmic intrinsic loss when long-term environmental EICs, estimated.
