Measured results and assessment of personal protection appliances against ionizing radiation / 中华放射医学与防护杂志

ABSTRACT

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.
