用(yong)于(yu)阻擋x射(she)線(xian)制(zhi)造(zao)防輻射(she)鉛(qian)(qian)(qian)門的(de)鉛(qian)(qian)(qian)板要求具(ju)有高純度(du)。大(da)約是99.9%。還要求鉛(qian)(qian)(qian)皮厚度(du)均勻(yun)。不允(yun)許有洞(dong)。如(ru)果鉛(qian)(qian)(qian)皮的(de)長度(du)和寬(kuan)度(du)不夠大(da)，允(yun)許用(yong)兩(liang)片鉛(qian)(qian)(qian)皮焊接。然而，鉛(qian)(qian)(qian)皮的(de)寬(kuan)度(du)應該超過10毫(hao)米。X射(she)線(xian)用(yong)于(yu)防護門的(de)鉛(qian)(qian)(qian)皮通(tong)常由幾(ji)層重疊(die)而成。它(ta)大(da)約1毫(hao)米厚。因為(wei)鉛(qian)(qian)(qian)皮又軟(ruan)又重，很容易(yi)掉下來。它(ta)需要放置(zhi)在(zai)兩(liang)塊(kuai)厚度(du)為(wei)1...
