The French Defence Radiation Protection Service (SPRA) conducted a study to assess the radiation exposure of personnel assigned to the maintenance of the Palmier radar in an Air Force Base. The aim of the study was the assessment of the annual effective doses received by personnel assigned to these maintenance operations, and the measurement of equivalent dose rates in the area in order to realise radiological zoning. In two measurement campaigns, the annual individual effective doses, measured by passive whole-body OSL Inlight ® dosimeters, consolidated the results obtained by radiometric measurements. Moreover, the equivalent dose rate shows wide variations in relation to the position of the operator in the emitter's area. From these results, the authors propose recommendations for categorisation of workers, radiological zoning and dose monitoring procedures. © 2012 EDP Sciences. Source

Purpose of the study: Medical and technical teams from the French defence radiation protection service (SPRA) conducted a study to quantify the ionizing radiation exposure to the interventional cardiology staff at the Percy military hospital. A delineation of areas is also assessed by the authors. Method: Effective and equivalent doses have been evaluated with whole-body InLight ® OSL and nanoDot® dosimeters for extremities and lens during several procedures. Ambient measurements have also been performed with AT1123® survey meters and have contributed to delineate areas. Conclusion: The authors propose the systematic implementation of collective protection means for the operators' feet and lens in interventional cardiology. They suggest the categorization of cardiologists and nurses in A and B categories respectively. Area delineation requires the compulsory wearing of passive and operational dosimeters to access the operating room during procedures. © 2012 Elsevier Masson SAS. All rights reserved. Source

The French defense radiation protection service (SPRA) and the French national institute for research and safety (INRS) conducted a joint study to assess the radiation exposure to operating room staff during prostate brachytherapy using iodine-125 seeds at the Val-de-Grĝce military hospital. The purpose of the study was the assessment of the effective doses, the equivalent doses to the extremities and lens received by a novice team, the different ambient dose equivalent rates measurements and the delineation of areas. After six brachytherapies, all the recorded doses with whole-body InLight® OSL and nanoDot® dosimeters remained below the detection limit for the whole staff. The dose rate measured at the end of implantation by an AT1123® survey meter is about 170 μSv/h at the perineum of the patient. The controlled area limit is estimated to be about 20 cm from the patient perineum. From these results, the authors propose recommendations for the categorization of workers, the delineation of areas and the dose monitoring procedures. This study demonstrates that real-time ultrasound-guided transperineal prostate brachytherapy delivers low dose to the operators because of the radioactive source characteristics and the instrumentation providing an effective radiation protection for the surgical team. © 2011 EDP Sciences.
