Effective atomic number studies in different biological samples for partial and total photon interactions in the energy region 10(-3) to 10(5) MeV.

Effective atomic numbers (Zeff) of 7 different biological samples containing several elements were computed for total and partial cross sections using theoretical data over a wide range of energy region from 10(-3) to 10(5) MeV. It has been found that Zeff changes with change in composition of the material and change in energy. The significant changes in Zeff of different biological samples are due to domination of different interaction processes in different energy regions as number of elements present is quite large in some biological samples (e.g. cell, bone, muscle).

Influence of the chemical composition on gamma ray attenuation by fatty acids.

The dependence of gamma ray attenuation on the chemical composition of fatty acids is investigated in the energy range from 10(-3) to 10(5) MeV. The mass attenuation coefficients (muF) and effective atomic numbers (Zeff) have been calculated for 27 different fatty acids. They show appreciable variation with the chemical composition of fatty acids in the region of gamma ray energies from 10(-3) to 10(5) MeV.
