A method of uranium direct determination by laser induced fluroscence ispresented- The kinds of samples determined include surface water

soil

biologicalmaterial and some contaminated soils. Results show that the method is sensitive andaccurate

with degree of variation 5%

10% and 20% for water

soil and biologicalsamples respectively. Results of inter-lab comparisions indicate that results from thismethod are of comparablity. Its high sensitivity and reliability

as well as itsconvemence and low cost will make this method a more attractive option forapplication to envirorunental monitoring.
