The aim of this study is to find an optimum material to protect garment for protection against T radionuclide.
Monte Carlo simulation code was applied to investigate radiation attenuation of 13 shielding materials including: Ba, gray Sn, white Sn, Sb, Bi, BiO, BaSO, Sn/W, Sb/W, Pb and W with thicknesses of 0.5 and 1 mm to determine an optimum protective garment material in nuclear medicine against Tc. Furthermore, the dose enhancement on the staff body was investigated for shielding materials such as tungsten and lead.
The findings of the simulations show that the maximum and minimum attenuation obtained with thicknesses of 1 mm W and 1 mm BaSO were 96.46% and 14.2%, respectively. The results also demonstrate that tungsten does not cause any dose enhancement on staff body but this is not true for lead. Tungsten provides the highest radiation attenuation without dose enhancement on the body of staff.
Among materials evaluated, tungsten is the optimum material and it can be applied for the design of protective garment for nuclear medicine staff against Tc.
本研究旨在寻找一种最佳材料，用于制作防护服装，以抵御锝放射性核素。
应用蒙特卡罗模拟代码研究13种屏蔽材料的辐射衰减情况，这些材料包括：钡、灰锡、白锡、锑、铋、氧化铋、硫酸钡、锡/钨、锑/钨、铅和钨，厚度分别为0.5毫米和1毫米，以确定核医学中针对锝的最佳防护服材料。此外，还研究了钨和铅等屏蔽材料对工作人员身体的剂量增强情况。
模拟结果表明，厚度为1毫米的钨和1毫米的硫酸钡所获得的最大和最小衰减分别为96.46%和14.2%。结果还表明，钨不会对工作人员身体造成任何剂量增强，但铅并非如此。钨在不增加工作人员身体剂量的情况下提供了最高的辐射衰减。
在所评估的材料中，钨是最佳材料，可用于设计核医学工作人员针对锝的防护服。
