Measurement of Total and Partial Mass Attenuation Coefficients of Oxide Glasses: A Radiation field
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
The variation in mass attenuation coefficient µ for total and partial photon interaction processes for three different oxide glasses (65CaO-35Al2O3(OG1) , 20Na2O-80SiO2(OG2), and 20Na2O-5Al2O3-75SiO2 (OG3)), in the incident energy range from 10 keV to 100 GeV has been studied using software package XCOM and the effect of chemical composition on the values of µ is also interpreted graphically. Mass attenuation coefficient (µ) for the total photon interaction processes is initially high and decreases sharply with increase in incident photon energy up to 100 keV. Above 100 keV the rate of decrease of µ (total) with incident photon energy is less and above 4 MeV µ (total) increases slightly with further increase in incident photon energy. Significant variations due to chemical composition can be observed below 3 KeV and above 30 MeV incident energy.
