Workshirts which had been worn by employees at a beryllium refinery were tested to assess whether wear significantly affects the amount of resuspended Be containing dust. Sections of six work shirts--three "new" (one washed, two unwashed) and three "old" (one washed, two unwashed)--were analyzed to measure the concentration of Be in the fabric. Additional swatches were agitated to resuspend Be particles inside a closed steel glove box. Air samples were taken with filter cassette monitors. After sampling, the fabric and filter samples were analyzed for beryllium. As a group, the old shirts resuspended significantly higher quantities of Be to the air than did the washed and unwashed new shirts. A considerable fraction of the Be measured in air was respirable.
对铍精炼厂员工所穿的工作衬衫进行了测试，以评估穿着是否会显著影响含铍粉尘的再悬浮量。分析了六件工作衬衫的部分——三件“新的”（一件洗过的，两件未洗过的）和三件“旧的”（一件洗过的，两件未洗过的），以测量织物中铍的浓度。在一个封闭的钢制手套箱内搅动额外的样本，使铍颗粒再悬浮。用滤盒监测器采集空气样本。采样后，对织物和滤膜样本进行铍分析。总体而言，旧衬衫向空气中再悬浮的铍量明显高于洗过和未洗过的新衬衫。空气中测得的相当一部分铍是可吸入的。
