【Abstract】 Radioactive uranium in urine was determined with laser-fluorescent technique for diagnosing uranium poisoning. The detection limits of this method were 0.05 ppb and 20 ppb, and the accuracy was ±15%.Practical use showed a satisfactory result. This technique is simple and quick, and reqiures only small sample.更多还原
