Plastic scintillator dosimetry in radiology applications

Plastics have attractive characteristics that can be exploit in dosimetry. Nevertheless their application with low-energy photon beam is still limited. We aim to a better understanding of their capabilities at the radiology regime. A study of the characteristics of a polystyrene scintillator dosimeter, coupled to a WLS fiber is made in this work. The energy dependence for this detector is extracted for photon beams between 20 and 100 kVp and additional filtrations of 0.5, 1 and 4 mm of Al.
