摘要：

An intercomparison of ring dosemeters has been organised with the aim of assessing the technical capabilities of available extremity dosemeters and focusing on their performance at clinical workplaces with potentially high extremity doses. Twenty-four services from 16 countries participated in the intercomparison. The dosemeters were exposed to reference photon (Cs-137) and beta (Pm-147, Kr-85 and Sr-90/Y-90) fields together with fields representing realistic exposure situations in interventional radiology (direct and scattered radiation) and nuclear medicine (Tc-99 m and F-18). It has been found that most dosemeters provided satisfactory measurements of H-p(0.07) for photon radiation, both in reference and realistic fields. However, only four dosemeters fulfilled the established requirements for all radiation qualities. The main difficulties were found for the measurement of low-energy beta radiation. Finally, the results also showed a general under-response of detectors to F-18, which was attributed to the difficulties of the dosimetric systems to measure the positron contribution to the dose.
