Determination of energy absorption and exposure buildup factors by using G-P fitting approximation for radioprotective agents.

摘要: AbstractPurpose: Recently, there has been an increase in interest into research radioprotective agents. Radioprotectors are compounds that protect against radiation injury when given orally (through drinking water) prior to exposure. The purpose is achieve preferred protection of normal tissues inflicted by ionizing used treat tumors. main aim this work investigate energy absorption (EABF) and exposure buildup factors (EBF) commonly some agents.Materials methods: We have the Geometric Progression (G-P) fitting method for calculating equivalent atomic number (Zeq), EABF EBF agents range 0.015–15 MeV penetration depths up 40 mean free path.Results: Significant variations both values were observed several at moderate region. At energies below 0.1 MeV, increased with decreasing at...
