The mass energy absorption coefficient (μen∕ρ), effective atomic number ( ), and electron density ( ) of some biomolecules with potential application in radiation dosimetry were calculated for their photon energy absorption (PEA) in the energy region of 1–20 MeV. It was noticed that the values of μen∕ρ, , and vary with the energy and composition of the biomolecules. The results for were compared with effective atomic numbers ( ) owing to the photon interaction (PI). Sig-nificant differences were noted between and in the energy region of 10–150 keV for all of the biomole-cules involved. A maximum difference of 45.36% was observed at 50 keV for creatinine hydrochloride. More-over, the studied attenuation parameters were found to be sharply affected at the K-absorption edge of relatively high-Z elements present in the biomolecules.
