Measurement of Natural Uranium in Urine by Fluorometry

摘要

The fluorometric method of measuring natural uranium in urine that is currently used by the Bioassay Laboratory at Chalk River Nuclear Laboratories has been tested, optimized and documented. The method, which measures the fluorescence of uranium in a fused sodium fluoride pellet, has been shown to be quench independent and is routinely used to measure uranium concentrations in the range of 1 mu g/L to 90 mu g/L. The fluorimeter has a dynamic range of 0.2 mu g/L to 200 mu g/L. (Atomindex citation 16:041773)
