Effect of weight fraction of different constituent elements on the total attenuation coefficients of some biologically important compounds

Pravina P. Pawar and Govind K.

Abstract

The total attenuation coefficients, μ/ρ, of some biologically important vitamins containing H, C, N and O have been studied as a function of weight fraction of constituent elements. A considerable change in μ/ρ is seen only in low energy region whereas no change is observed with the increasing percentage of constituent elements (hydrogen, carbon, oxygen and nitrogen) in high energy region up to 1500 keV.
