Abstract: This report describes dosimetry techniques used by EURADOS Working Group 9 (Radiation Dosimetry in Radiotherapy) to measure out-of -field doses for use in radiotherapy. Several passive dosimeter types were used, based on the physical principles of thermoluminescence (TLD), optically simulated luminescence (OSL) and radiophotoluminescence (RPL), in addition to an ionization chamber used as a reference standard. Superheated drop, bubble damage and track etch detectors were used specifically for neutron measurements. In this report, doses...

Abstract: The medical staff performing interventional cardiology and radiology (IC/IR) procedures stand close to the patient and thus close to the primary radiation beam. Although they wear a lead apron and thyroid collar, their hands, legs and eyes are not protected. Therefore, these parts could receive significantly high doses. Moreover, thedose ranges for the same kind of procedures vary a lot, as many factors affect extremity and eye lens doses. Additionally, there is evidence that...

Abstract: This report is the final outcome and summary of the work of the EURADOS WG12, Sub-Group (SG) 3: Technical aspects on DAP calibration and CT calibration. Management of patient dose in the high dose procedures of interventional radiology (IR) and computed tomography (CT) requires regular and accurate determinations of the practical dose quantities, which are relevant for the basis of actual patient dose determination and setting of the diagnostic reference levels (DRL) or trigger...
