INTERCOMPARISON OF PERSONAL DOSIMETRY SYSTEMS FOR PHOTON RADIATION INTHE LATIN-AMERICAN REGION

Under the ARCAL/IAEA programme, the LNMRI/IRD-CNEN promoted the third Latin American intercomparison of personal dosimetry systems during 19 92. Ten countries participated in the study by sending personal doseme ters used for whole-body monitoring in photon radiation fields to be i rradiated at LNMRI over a wide range of photon energies and angles. Ba sed on the evaluation of the dose equivalent reported by the participa nts, the LNMRI analysed the performance of each personal dosimetry sys tem regarding its reproducibility, energy dependence, angular dependen ce and its accuracy. It was concluded that most participants' personal dosimetry systems should have their energy and angular dependence red uced. A step forward is suggested towards the implementation of the IC RU operational quantities in the region.
