[ 1 ] - بررسی مکان و راستای آشکارساز جهت مینیمم نمودن ضریب انباشت شار پرتوهای گاما

The purpose of this study is to select the best place for the detector towards shield and the gamma source which have the least flux buildup factor of the photon. In this research, the flux buildup factor of gamma rays was calculated by using of MCNP-4C code for cylindrical sources 137Cs, 60Co, 16N coaxial shields made up of aluminum, iron and lead with a constant thickness 1.55 cm in detec...
