Abstract Objective To establish a method for uranium aerosol sample collection, dry ashing treatment, and laboratory laser-fluorescence measurement in the workplace of uranium processing and fuel fabrication facilities. Methods Through optimization experiments, the effects of sampling flow, sample pH value, and test temperature on uranium aerosol concentration results were studied, and the detection limit, precision, and recovery rate of the method were tested. Results Under the optimal test conditions, the detection limit of the method was 0.025 ng/mL; the minimum detectable concentration of 1 m3 of aerosol samples was 1.25×10-3 μg/m3; the relative standard deviation (RSD) of the measurement results was less than 5%; the recovery rate was between 96% and 104%. Conclusion The detection limit, precision, and accuracy of the method meet the testing requirements for uranium aerosol samples in the workplace of uranium processing and fuel fabrication facilities.
