Abstract:
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.
