| 目的 通过有效监测个人防护用品防护质量,探讨促进个人防护用品的研制和开发,以保障放射工作人员的健康与安全。方法 应用标准铅片迭代法测量个人防护用品和材料的铅当量厚度,用"mm Pb"表示。共检测了77件产/样品,其中铅橡胶板37件,各类个人防护制品27件,包括防护服12件、防护帽4件、防护围脖5件、防护手套4件和防护面罩2件;其中铅玻璃眼镜13件。结果 铅橡胶板比铅当量分别在0.20~0.39 mm Pb/mm之间,铅橡胶板比铅当量在0.25 mm Pb/mm以下有6件,不符合相关标准的要求。个人防护制品和铅玻璃眼镜检测结果表明,实测铅当量均大于标称铅当量。结论 国产和进口的个人辐射防护材料及用品的防护质量是可靠的,但介入防护手套的防护质量有待于提高和改进。 |

| Objective To monitor the protective qualities of personal protective appliances and to ensure the health and safety of radiological working personnel. Methods The lead-equivalent thickness of personal protective appliances and materials was measured by means of standard lead slices. The lead equivalent thickness represents in terms of mm Pb. Results 77 pieces of products and samples were measured altogether. The results indicate that the specific lead equivalents of lead-rubber plates were between 0.20-0.39 mm Pb/mm for 37 pieces of lead-rubber plates and the values of 6 pieces of samples were less than 0.25 mm Pb/mm,which did not accord with the requirement of the relational standard. 27 pieces of personal protection appliances were measured altogether. They were 12 pieces of protective clothes, 4 pieces of protective headgears, 5 pieces of protective neckpieces, 4 pieces of protective gloves and 2 pieces of protective masks. 13 pairs of lead-glass spectacles among them were measured altogether. The measured results for personal protective appliances and lead-glass spectacles showed that actually measured lead-equivalent were higher than the nominal lead-equivalent.Conclusions The protective qualities are reliable for personal protection materials and appliances to be made in home and imported abroad. But the protective qualities of interventional protection gloves should be improved and made them better. |
