| Abstract:: |
| Objective To explore the applicable conditions for using urine uranium monitoring data to assess personal internal doses with a view to providing references for the occupational health management and the urine uranium monitoring in nuclear industry sector. Methods The urine uranium levels were calculated, through simulation calculation set at 1 mSv effective dose arising from either acute or chronic ingestion of uranium compounds. The results were compared with the monitoring values of workers without occupational exposure history. The feasibility of urine uranium monitoring for dose assessment of internal radiation exposure was discussed. Results For special monitoring of acute ingestion, liquid fluorimetry can meet monitoring requirements of Type F uranium compound, Type M low enriched uranium and Type S naturally occurring uranium. For routine monitoring, only Type F low enriched uranium and Type M naturally occurring uranium can be detected at shorter monitoring intervals, But it was not suitable for Type S uranium compounds. Conclusions Background levels and detection limits should be considered when urine uranium is measured for the purpose of assessment or control of exposure to uranium and the interpretation of the results. |
