Abstract
Active personal dosemeters (APD) have been found to be very efficient tools to reduce occupational doses
in many applications of ionizing radiation. In order to be used in interventional radiology and cardiology
(IR/IC), APDs should be able to measure low energy photons and pulsed radiation with relatively high
instantaneous personal dose equivalent rates. A study concerning the optimization of the use of APDs in
IR/IC was performed in the framework of the ORAMED project, a Collaborative Project (2008e2011)
supported by the European Commission within its 7th Framework Program. In particular, eight
commercial APDs were tested in continuous and pulsed X-ray fields delivered by calibration laboratories
in order to evaluate their performances. Most of APDs provide a response in pulsed mode more or less
affected by the personal dose equivalent rate, which means they could be used in routine monitoring
provided that correction factors are introduced. These results emphasize the importance of adding tests
in pulsed mode in type-test procedures for APDs. Some general recommendations are proposed in the
end of this paper for the selection and use of APDs at IR/IC workplaces.
