目的 从辐射和化学危害角度分别推算F类铀化合物导出空气浓度,为工作场所职业危害因素的管理与评价提供参考.方法 用模拟计算的方法,分别推算F类铀化合物达到个人年剂量限值、急慢性机体损害效应阈值时工作场所的空气浓度.结果 正常运行情况下,将工作场所空气中F类铀化合物浓度控制在5 μg/m3以内,可以满足辐射危害和化学危害控制的要求;短时间开放性接触时,控制在1.1 mg/m3是可以接受的.结论 制定F类铀化合物空气浓度限值是可行的.
目的 從輻射和化學危害角度分彆推算F類鈾化閤物導齣空氣濃度,為工作場所職業危害因素的管理與評價提供參攷.方法 用模擬計算的方法,分彆推算F類鈾化閤物達到箇人年劑量限值、急慢性機體損害效應閾值時工作場所的空氣濃度.結果 正常運行情況下,將工作場所空氣中F類鈾化閤物濃度控製在5 μg/m3以內,可以滿足輻射危害和化學危害控製的要求;短時間開放性接觸時,控製在1.1 mg/m3是可以接受的.結論 製定F類鈾化閤物空氣濃度限值是可行的.

Objective Derived air concentration of Type F uranium compounds are calculated respectively in order to provide reference for the management and evaluation of occupational hazard factors in workplace.Methods The air concentrations in the workplace of Type F uranium compounds were derived respectively through numerical simulationn,from individual dose limits,acute poisoning and chronic chemical damage threshold.Results Under normal operation conditions,the concentration of 5 μg /m3 for Type F uranium compounds in air of workplace can meet the requirements of radiation and chemical hazard control.Open inhalation of 1.1 mg/m3 is acceptable in a short time.Conclusions It is feasible to establish a permissible concentration limit in workplace for Type F uranium compounds.
