Comparison of radiation shielding properties of some coordination polymers

Abstract

We have studied the X-ray and gamma radiation shielding parameters such as mass attenuation coefficient, linear attenuation coefficient, mean free path, half-value layer, tenth-value layer, effective atomic numbers, electron density, exposure buildup factors, specific gamma-ray constant, and mechanical properties in some coordination polymers such as lead monoclinic-(I), lead monoclinic-(II), lead tetragonal, azelato barium (II) polymer, 1-D coordination barium polymer (I), helical lead (II) coordination polymer, calcium bromide polymer (I), calcium bromide polymer (II), 1D-cadmium coordination polymer, and 2D-cadmium coordination polymer. We have also studied the neutron shielding properties in the same coordination polymers. From the detailed study, it is clear that helical lead (II) coordination polymer is a good absorber for X-ray and gamma radiation. The attenuation parameters for neutron are higher for 1D coordination barium polymer (I) compared to that of other studied polymers. This work is useful in the field of radiation shielding.
