发布时间:2018-09-11 19:45
【摘要】:目的比较铅橡胶射线防护品在不同被覆材料及不同缝合方式时的铅防渗效果。方法测定4个时间点的8个琼脂块载体样本点的铅含量,共测5次,经数据有效性处理后,计算两种射线防护制品的表面及边缘的铅渗出量及铅渗出比率。结果两种样品表面及边缘在0.5、1、3、5 h 4个时间点每组铅渗出量差异均无统计学意义(P0.05)。样品表面及边缘的铅渗出量及铅渗出比率尼龙TPU复合布周边热合加工的防护品均明显低于尼龙布周边缝合的防护品;两种样品的铅渗出量边缘均比表面要高,差异均有统计学意义(P0.01)。尼龙TPU复合布周边热合加工的防护品表面及边缘铅渗出比率数值数量级分别为10-5和10-4;尼龙布周边缝合防护品分别为10-3和10-1。结论双层封闭的尼龙TPU复合布周边热合加工的铅橡胶防护品比尼龙布周边缝合的防护品显著减少铅渗出。
[Abstract]:Objective To compare the anti-seepage effect of lead rubber protective products with different coating materials and different suture methods.Methods Lead content in 8 samples of agar block carrier at 4 time points was measured for 5 times.After data validity treatment,the lead leakage and lead leakage ratio on the surface and edge of two protective products were calculated. There was no significant difference in lead leakage between the two groups at 0.5, 1, 3, and 5 h (P 0.05). The surface and edge lead exudation ratios were 10-5 and 10-4, respectively, and 10-3 and 10-1, respectively. Conclusion The lead rubber protective products of double-layer closed nylon TPU composite fabric were better than that of nylon TPU composite fabric. Cloth around stitched protective products significantly reduced lead exudation.
