RADIOLOGICAL PROPERTIES OF THE PAGAT GEL DOSIMETER AND THE PRESAGE POLYMER DOSIMETER

摘要

This study has determined the radiological properties of the PAGAT gel dosimeter and the PRESAGE polymer dosimeter using Monte Carlo modelling. The mass density (ρ), mass attenuation coefficients (μ/ρ), mass energy absorption coefficients (μ_(en/ρ)). electron mass stopping powers (S/ρ) and electron mass scattering powers (T/ρ) were calculated and compared to the values of water over the therapeutic x-ray energy range.
