A MULTILABORATORY TESTING OF CALIBRATION METHODS FOR ENVIRONMENTAL DOSE RATE METERS
Calibration experiments were carried out at Risoe National Laboratory 28-30 August 1985 with the aim of testing calibration methods for instruments used for background gamma radiation monitoring. Two calibration methods using certified gamma sources were tested: 1) A shadow shield calibration method, and 2) A free field calibration set-up. The experiments comprised studies of 25 instruments from 11 European laboratories. For most of the instruments the two methods gave identical results. The shadow shield calibration, however, proved to be more accurate. Additional measurements of the natural background and the cosmic component gave useful information on the energy dependency of the detectors. The calibration experiments were sponsored by CEC under contract No. 1244/1/84.
