  • Intercomparison of environmental gamma dose rate meters : A comprehensive study of calibration methods and field measurements - Part II 1987-1989 experiments


The measurement of ambient radiation in the neighbourhood of a nuclear installation is essential, to demonstrate that members of the public are not exposed to unacceptable levels of radiation arising from the operation of the installation. In the light of the results of two studies conducted in 1984 and 1985 (Report EUR 11665 EN), the Commission decided to continue investigations in the field of environmental gamma dose rate meters and, particularly, to extend the work to exposures above normal environmental levels. This report, describing the results of the studies carried out between 1987 and 1989, leads to a number of conclusions of significance to those involved in the measurement of environmental gamma radiations, in particular that natural background measurements show a significant spread mainly due to the different responses of the detectors to the cosmic radiation. It may also be necessary to take the proximity of people into account when making environmental measurements.
