An attempt has been made to estimate the effective atomic number, electron density (0.001 to 10$^5$ MeV) and kerma (0.001 to 20 MeV) of gamma radiation for a wide range of oxides of lanthanides using mass attenuation coefﬁcient from WinXCom and mass energy absorption coefﬁcient from Hubbell and Seltzer. The values of these parameters have been found to change with energy for different oxides of lanthanides. The lanthanide oxides ﬁnd remarkable applications in the ﬁeld of medicine, biology, nuclear engineering and space technology. Nano-oxides of lanthanide ﬁnd applications in display and lighting industry.
