摘要

制作了复合材料的实验样品。这些复合材料以聚苯乙烯为基础，用铝粉增强，并添加了钨粉以屏蔽辐射。通过实验选择了生产设备的最佳运行模式。在 250、290 和 320 К 的温度下对复合材料进行了拉伸试验。温度为 290 К 时的最大拉伸强度为 45 兆帕。具有这种强度的复合材料在制作临时或永久性辐射屏蔽结构时不会被破坏。使用 Geant4 v 4.9.6p03 代码对吸收剂量的相对衰减进行了计算。厚度为 10 毫米的复合材料层可完全吸收能量高达 100 千伏的电离辐射。固体层的最大半衰减水平能量为 600 千伏安，球和松散层的最大半衰减水平能量为 300 千伏安。

BRIEF OVERVIEW ON RESEARCH AND DEVELOPMENT OF RADIATION SHIELDING PROTECTIVE COMPOSITE MATERIALS BASED ON POLYSTYRENE

Experimental samples of composite materials were made. These composites are based on polystyrene, which has been reinforced with powder of aluminum, with the addition of powder of tungsten for radiation shielding. The optimum modes of operations of production equipment were selected experimentally. Tensile testing of composite materials was carried out at temperatures of 250, 290, 320 К. The maximum tensile strength, at a temperature of 290 К, was a value 45 MPa. Composites with such strength are not destroyed when creating temporary or permanent radiation shielding structures. Using the code Geant4 v 4.9.6p03, calculations of the relative attenuation of the absorbed dose were performed. A layer of composite material 10 mm thick completely absorbs ionizing radiation with energies up to 100 keV. The energy for maximum half-attenuation level is 600 keV for solid layer and 300 keV for balls and loose layer.
