The current study involves the X-ray/gamma and neutron/EMI shielding and change in mechanical properties of selected lanthanide polymers such as Lanthanum polymer, Cerium polymer, Praseodymium polymer, Gadolinium texaphyrin polymer, Terbium co-ordination polymer and Erbium phosphate hydrate polymer. The X-ray/gamma, neutron and EMI shielding parameters are studied in detail for all the selected polymers. Among all the selected polymers, Erbium phosphate hydrate polymer shows larger values of mass attenuation coefficient, absorption buildup factor, Z_eff, N_e, specific absorbed fractions of energy, radiation protection efficiency, kinetic energy released in matter, relative dose, neutron total interaction cross section and absorption cross section values. Furthermore, the EMI shielding parameter (total shielding effectiveness) was also found to be larger for Erbium phosphate hydrate polymer in near infrared, mid infrared, far infrared, ultra high frequency (UHF), very high frequency, high frequency radio waves, middle frequency radio waves, low frequency radio waves and very low frequency radio waves. This clearly indicates that Erbium phosphate hydrate polymer might be used as a good shielding material for X-ray/gamma, neutrons and EMI radiations. We have also reported the change in mechanical properties of the studied lanthanide polymers due to the interaction with X-rays/gamma rays. The mechanical properties remains unchanged in the region where pair production and photoelectric effect dominates. Change in the mechanical properties is observed in the region where Compton scattering dominates, indicating that the change in mechanical properties due to interaction of radiation is also an important parameter while selecting the shielding materials. Present study may be useful in the selection of new shielding material.

目前的研究涉及 X 射线/伽马和中子/EMI 屏蔽和选定镧系元素聚合物的机械性能变化，例如镧聚合物、铈聚合物、镨聚合物、钆 texaphyrin 聚合物、铽配位聚合物和磷酸铒水合物聚合物。详细研究了所有选定聚合物的 X 射线/伽马、中子和 EMI 屏蔽参数。在所有选定的聚合物中，磷酸铒水合物聚合物的质量衰减系数、吸收累积因子、Z _eff、N _e值较大、特定吸收的能量分数、辐射防护效率、物质中释放的动能、相对剂量、中子总相互作用截面和吸收截面值。此外，还发现磷酸铒水合物聚合物在近红外、中红外、远红外、超高频 (UHF)、甚高频、高频无线电波、中频中的 EMI 屏蔽参数（总屏蔽效率）更大无线电波、低频无线电波和极低频无线电波。这清楚地表明，磷酸铒水合物聚合物可用作 X 射线/γ、中子和 EMI 辐射的良好屏蔽材料。我们还报道了由于与 X 射线/伽马射线的相互作用，所研究的镧系元素聚合物的机械性能发生了变化。在对产生和光电效应占主导地位的区域，机械性能保持不变。在康普顿散射占主导地位的区域观察到机械性能的变化，表明由于辐射相互作用引起的机械性能变化也是选择屏蔽材料时的重要参数。目前的研究可能有助于选择新的屏蔽材料。
