Abstract

The Ionising Radiations Metrology Forum (IRMF) organised a second intercomparison of calibrations of gamma-ray dose-rate monitors in which sixteen establishments in the UK participated. The exercise involved the circulation of four gamma-ray monitors for calibration in the fields produced using 137CS, 6OCO and 241 Am. The instruments used were an NE technology PDM1B, a Mini-Instruments Mini-Rad (1000R), a Mini-InstrumE~nts Mini-900 with 44A Probe and a Siemens Electronic Personal Dosemeter.
All results were submitted to the authors for analysis. Responses relative to 'true' air-kerma rate, as stated by the individual participants, were calculated. The results, reported anonymously, are compared and demonstrate generally satisfactory agreement between establishments.
