Abstract

Goal of the present work is the dose distribution of biological material by X-ray and g-photon at 0.015 to 15 MeV up to penetration depth 40 MFP. The mass attenuation coefficient, effective atomic number (Zeff), effective electron density (Neff) were calculated at 1 keV to 100 GeV and energy absorption build-up factor (EABF) and energy absorption build-up factor (EBF) at 0.015 to 15 MeV upto the penetration depth 40 mfp of selected unnatural amino acids are N-acetyl-L-tryptophan, N-acetyl-tyrosine, D-tryptophan, N-acetyl glutamic acid, D-phenylalanine, D-threonine. The build-up factors obtained with the function of the incident photon energy penetration depth, effective atomic number (Zeff) and effective electron density (Neff). The value of EABF and EBF maximum their Compton scattering was the main interaction process. The EABF and EBF versus Zeff and Neff at 0.015, 0.02, 0.03, 0.04, 0.05, 0.06, 0.08, 0.1, 0.15 MeV shows Zeff and Neff enhancing the value of EABF and EBF decreases. Zeff and Neff parameter are dependent on incident photon energy.
