Abstract

The polymer gel dosimeter using the radical polymerization reaction of organic monomer enables small volume measurement of dose. In this work, we evaluate the simulated results are compared to depth dose distributions measured with polymer gel dosimeters for small volume objects. And also the polymer gel’s water equivalency by means of calculations on the attenuation and ionization of radiations, and Monte Carlo simulations on the transport of electron and photon respectively in water and polymer gel.
