Özet

The aim of this study is to evaluate the water equivalency of metal doped PAGAT gel dosimeter in terms of its effective atomic number. Auto-Zeff software and NIST XCOM data base were used to perform this study. Initially Gold (Au) and Silver (Ag) were taken and divided into different concentration (from 0.01 to 100Mm) with standard PAGAT formalism and the elemental composition was determined. Using these elemental compositions Z(eff) was generated for photon interaction using Auto-Z(eff) software. Au doped gel was found as a water equivalent in the concentration range of 0.01 to 0.1Mm. Ag doped gel have matched well with water from 0.01 to 1Mm concentration in terms of water equivalence. In these concentrations, it has been concluded that metal doped gel is more water equivalent than plain PAGAT gel based on the Z(eff) data obtained.
