Abstract: The recent development of the spectral method for correction of the Cˇ erenkov light in plastic scintillation detectors (PSD) have led to the first commercial dosimeter of this type, the Exradin W1 (STANDARD IMAGING INC., Middleton, WI, U.S.). As any new commercial dosimeter, it had to be characterized and validated in different situations of radiation. The first purpose of this project was to perform this validation. The results of characterization have shown that PSD is an efficient dosimeter to make out-of-field doses measurements as required in the evaluation of the feasibility of using a lead sheet to reduce dose to Cardiac Implantable Electronic Devices, CIED. Measurements performed with PSD shown an important reduction of doses by the shielding for square anterior-posterior field (40 % to 80 %) and also for complex clinical treatments (5 % to 45 %).
