Abstract
Mass attenuation coefficient, \( \mu_{m} \), atomic cross-section, \( \sigma_{i} \), electronic cross-section, \( \sigma_{e} \), effective atomic number, \( Z_{\text{eff}} \) and effective electron density, \( N_{\text{el}} \), were determined experimentally and theoretically for some vitamins (retinol, beta-carotene, thiamine, riboflavin, niacinamide, pantothenic acid, pyridoxine, biotin, folic acid, cyanocobalamin, ascorbic acid, cholecalciferol, alpha-tocopherol, ketamine, hesperidin) at 30.82, 59.54, 80.99, 356.61, 661.66 and 1,408.01 keV photon energies using a NaI(Tl) scintillation detector. The theoretical mass attenuation coefficients were estimated using mixture rules. The calculated values were compared with the experimental values for all vitamins.
