Abstract Due to the inevitable harmful effects of radiation when conducting reactor repair, the robots made of rigid materials have been developed to replace human engineers. Anti-irradiation reinforcement of electronic components is a key issue for robots operating in a radioactive environment. A pneumatic-actuator soft robot was initially proposed for use in this study, due to the advantages of using fewer electronic components that require shielding from gamma rays. This paper presents a novel gamma ray radiation-resistant deformable material for the manufacture of soft robots. Here, the robot partially made of the silicone/W-based composites has the advantages of flexibility and gamma ray shielding property, which provide a novel solution for the collection of the radioactive objects and the detection of the radioactive environmental parameters, such as the temperature. The gamma ray attenuation and tensile elongation properties of the silicone/W and silicone/W/Bi2O3 composites were evaluated, and the surface morphology and lattice structures of the samples with the best radiation attenuation were investigated and analysed. The gamma ray shielding was experimentally assessed by using a60Co radioisotope. The test results demonstrated that the gamma transmittance of the silicone/W-based composite reached 0.64452, which was a decrease of approximately 30.0% when compared to pure silicone.

摘要 由于在进行反应堆维修时不可避免地会产生辐射的有害影响，因此开发了由刚性材料制成的机器人来代替人类工程师。电子元件的抗辐射加固是机器人在放射性环境中运行的关键问题。由于使用较少需要屏蔽伽马射线的电子元件的优点，最初建议在本研究中使用气动执行器软机器人。本文提出了一种用于制造软机器人的新型抗伽马射线辐射可变形材料。在这里，部分由硅/钨基复合材料制成的机器人具有柔韧性和伽马射线屏蔽性能的优点，为放射性物体的采集和温度等放射性环境参数的检测提供了一种新的解决方案。评价了有机硅/W和有机硅/W/Bi2O3复合材料的伽马射线衰减和拉伸伸长性能，并对辐射衰减最好的样品的表面形貌和晶格结构进行了研究和分析。伽马射线屏蔽通过使用 60Co 放射性同位素进行实验评估。测试结果表明，有机硅/W基复合材料的伽马透射率达到0.64452，与纯有机硅相比降低了约30.0%。并对辐射衰减最好的样品的表面形貌和晶格结构进行了研究和分析。伽马射线屏蔽通过使用 60Co 放射性同位素进行实验评估。测试结果表明，有机硅/W基复合材料的伽马透射率达到0.64452，与纯有机硅相比降低了约30.0%。并对辐射衰减最好的样品的表面形貌和晶格结构进行了研究和分析。伽马射线屏蔽通过使用 60Co 放射性同位素进行实验评估。测试结果表明，有机硅/W基复合材料的伽马透射率达到0.64452，与纯有机硅相比降低了约30.0%。
