    In this study, manganese nano substituted hydroxyapatite artificial bone powders (nMnHAp) have been investigated experimentally by means of mass attenuation coefficients, effective atomic numbers and electron densities. The samples were irradiated using 778 keV, 964 keV, 1085 keV, 1112 keV, 1408 keV and 1457 keV gamma photons from 152Eu source .The gamma photons from the source were counted by using a HPGe gamma-ray spectroscopy. The mass attenuation coefficients of the hydroxyapatites artificial bone powders (including hydroxyapatite without any substituted metal and real bone powder) were compared with each other. This study has been dealt with as a guide to medical field. Also the results have been evaluated in terms of the electron density and effective atomic number.
