dc.description.abstractIn this study, the gamma radiation absorption capabilities of some metal borides were studied by using Monte Carlo simulation method. So, the mass attenuation coefficients, ? m , the half value layer, HVL, the tenth value layer, TVL and the mean free path, MFP values of the NdB 6 , SmB 6 and GdB 6 were calculated by means of EGSnrc particle transport code and XCOM program theoretically within the energy range 0.125–5 MeV. It was seen that there is a quite successful consistency (t = 0.00049, p = 0.99961) between the simulated results and calculated values obtained by NIST's XCOM photon cross-section database. Those computational results for the synthesized compounds have also been compared with lead and vermiculite which have concluded that NdB 6 , SmB 6 , and GdB 6 are good candidates for gamma shielding applications. These materials were sythesized by magnesiothermic reduction in open air. Stoichiometric amounts of M 2 O 3 , B 2 O 3 and Mg (20% excess) were mixed, where M III is a lanthanide metal (Nd III , Sm III and Gd III ) ion. Mixture was heated to 700 °C, 800 °C and 900 °C. Optimum reaction temperature and reaction time were found by X-Ray Diffraction (XRD) analysis and Scannning Electron Microscopy (SEM). By fixing the reaction temperature, reaction time has changed as 1, 2, 3, 4 and 5 h to obtain nano crystals with homogeneous morphology. It was found that optimum reaction temperature and reaction time of NdB 6 is 700 °C and 3 h, for SmB 6 700 °C and 1 h for GdB 6 900 °C. © 2019en_US
