Orthovoltage to Monoenergetic Photon Beam Energy Correction Factor for HyperScint Scintillation Dosimeter

The HyperScint scintillator dosimetry system from MedScint is a small-field dosimeter with reported energy independence down to 100-keV. This work investigates the energy dependence of the scintillator between a monoenergetic photon source and polyenergetic orthovoltage beam.

On the Use of a Commercial Plastic Scintillation Detector for Determination of Detector-Specific Small Field Output Correction Factors of Other Detectors

The goal of this work is to determine small field output correction factors of various detectors using a commercial plastic scintillation detector as a reference and to compare values with current available data.

External beam irradiation angle measurement using Cerenkov emission

Due to its angular dependency, Cerenkov light has long been considered a contamination signal in plastic scintillating dosimeters.
