About the report
The measurement of uranium in the urine of workers exposed to uranium dusts and solutions can assist in assessing the effectiveness of protective measures and the significance of actual exposures.
Most laboratories with uranium-in-urine measurement capabilities are not well practised in the measurement, therefore an interlaboratory comparison was undertaken to give laboratories practice in the technique and to check the accuracy of results. Ten laboratories took part in an intercomparison.
This paper describes the preparation of the samples and gives the results and statistical analysis of the results with respect to analytical method and laboratory performance.
Some laboratories experienced difficulty and, if required to perform future determinations of uranium in urine of exposed individuals, would need to demonstrate greater reliability in this type of analysis.
