Intercomparison of personal radiation monitoring services in the Asia/Pacific Region

Technical Report:

Abstract

The Australian Radiation Laboratory in 1991 conducted an International Intercomparison of Personal Radiation Monitoring Services in the Asia/Pacific region. Twenty nine organisations from sixteen countries took part in the study, with the People`s Republic of China having the greatest number of participants. Both thermoluminescent dosemeters (TLD) and conventional film badge dosemeters were submitted for evaluation. The intercomparison involved participants submitting 25 dosemeters including transit controls to the Australian Radiation Laboratory for exposure. Seven radiation beams of varying beam quality were used. Both film dosemeters and TLDs were irradiated with {sup 137}Cs gamma rays, X-rays, X-rays and 2.0 MeV maximum energy beta rays from a {sup 90}Sr/{sup 90}Y source. Seventeen dosemeters were exposed to the photon beams at normal incidence, four at a time, on a slab phantom made from a 5.5 cm thick perspex block backed by 20 cm of paper. Two dosemeters were exposed to beta rays at normal incidence. The delivered dose equivalents were in the range 0.2 to 2 mSv. Participants were requested to assess their dosemeters in terms of the International Commission on Radiation Units and Measurements (ICRU) new operational quantities for personal monitoring, namely the individual dose equivalent, superficial H{sub 2}(0.07) and individual dose equivalent,  More>>
