Design of tissue equivalent scintillators for precise dosimetry purposes

Abstract

A tissue equivalent plastic scintillator containing Chlorine has been designed through Monte Carlo simulations and mass energy transfer coefficient calculations, searching for the optimum concentration of that element whose role is to make the value of the absorbed radiation energy equal in tissue and plastic scintillators. The plastic is obtained by mixing the base component of most current plastic scintillators, Poly-Vinyl-Toluene, with Vinyl-Benzyl-Chloride. In addition, we propose two kinds of plastics, one for diagnostic X-rays and another one for therapy.
