Abstract

Radiation shield ing aprons are needed by radiation workers to minimize radiation exposure to the body. The apron s at present use fabric-coated lead plates which are heavy and rigid materials and therefore are not comfortable to use. Polymer aprons from cassava starch and glycerin with addition of Pb- nitrate filler at 0 %, 2 %, 4 %, and 6 % have been synthesized. Mixtures for synthesizing the polymer apron composites were heated using a magnetic stirrer at a speed of 800 rpm at 160 °C for 25 minutes. Then, the polymer apron composites were dried in an oven for 24 hours at 70 °C. The effectiveness of the apron was determined by calculating the attenuation coefficient ( μ ), half-value layer (HVL), and radiation absorption. The mechanical properties of the aprons were characterized by testing their tensile strengths using an A&D MCT-2150 universal tester. The result shows that the optimal addition of Pb- nitrate filler of as much as 6 % produced aprons with an attenuation coefficient of 1248 cm ‑1 , HVL of 0.54 cm, and radiation absorption of 25 % , while the aprons’ tensile strength was obtained as 28.244 MPa. T he addition of Pb-nitrate as a filler in apron composites proportionally improves the quality of materials used as radiation shields. More detailed research is still needed to obtain the best apron.

在X射线屏蔽用聚合物复合胶圈上添加硝酸铅填料

辐射防护围裙是辐射工作者需要的，以尽量减少辐射对身体的暴露。目前的围裙使用织物涂层铅板，这是一种沉重而坚硬的材料，因此使用起来不舒服。以木薯淀粉和甘油为原料，添加0%、2%、4%和6%的硝酸铅填料，合成了聚合物围裙。使用磁力搅拌器在160°C下以800rpm的速度加热用于合成聚合物围裙复合材料的混合物25分钟。然后，将聚合物围裙复合材料在70°C的烘箱中干燥24小时。通过计算衰减系数（μ）、半值层（HVL）和辐射吸收来确定护坦的有效性。通过使用A&D MCT-2150万能测试仪测试围裙的拉伸强度来表征围裙的机械性能。结果表明，硝酸铅填料的最佳添加量为6%，可制得衰减系数为1248cm-1、HVL为0.54cm、辐射吸收率为25%的围裙，而围裙的抗拉强度为28.244MPa。在围裙复合材料中添加硝酸铅作为填料，可按比例提高用作辐射防护罩的材料的质量。为了获得最佳停机坪，还需要进行更详细的研究。Normal 0 false false EN-US X-NONE X-NONE/*样式定义*/table。MsoNormalTable｛mso style name:“Table Normal”；mso tstyle行带大小：0；mso ts style行带尺寸：0；mso style noshow:yes；mso style优先级：99；mso样式父级：“”；mso填充alt:0cm 5.4pt 0cm 5.4pt；mso对位页边顶部：0cm；mso对位边距右侧：0cm；mso段落边距底部：10.0pt；mso对位左边距：0cm；线高：115%；mso分页：寡妇孤儿；字体大小：11.0pt；font-family:“Calibri”，“sans-serif”；mso-ascii font-family:宋体；mso-ascii主题字体：小拉丁文；mso-hansi font-family:宋体；mso-hansi主题字体：小拉丁文；mso-bidi字体家族：“Times New Roman”；mso-bidi主题字体：minor bidi；｝
