| 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. |
