    X-ray and gamma-ray have been frequently used worldwide for different aims such as scans, diagnostic, and therapeutic applications. While these processes occur for the aims, people unintentionally receive various doses of these rays which are highly energetic. Thus, electronic and energy transfer cross-sections, Compton mass attenuation coefficients, Compton mass energy transfer coefficients (CMETC) according to effective charges and charge to atomic weight ratios should be investigated for our health especially organs or dosimetric materials. In the present study, these parameters have been studied using Klein-Nishina approach in the wide energy region. The cross-sections have been firstly calculated in the photon energies. The investigated parameters of the materials have been then determined using the relevant cross-sections and effective atomic numbers in the same energy range. The results were compared with each other and some possible results from the literature. A good agreement was observed for electronic and energy transfer cross-sections (Diff. <= 0.16%). In addition, a comparison with the literature was conducted for possible materials at certain photon energies, and maximum difference (%) in soft tissue was observed up to around 33.61% for CMETCs. The reported data should be useful using the gamma rays in medicine and dosimetry applications.
