Design and Characterization of Shielding Materials for Electronics of Nuclear Robot

doi:10.3901/JME.2017.21.031

Abstract

Abstract: MCNP4C software was used to design shielding packaging materials and simulate its shielding performance, which is also measured under Co-60 irradiation with both low and high dose rate. It shows that the simulation value is very close to the test results. The linear attenuation coefficient and shielding percent of the composites increase with the increment of tungsten filler loading, while their half value layer drops. The tungsten/alumina composite with 70% tungsten fillers (W/Al-70) shows best overall performance. Compared with that of epoxy resin and alumina packaging materials, the linear attenuation coefficient of W/Al-70 increased 3.79 and 1.13 times, and its half value layer decreased by 7.04 cm and 2.06 cm, respectively.
