A liquid scintillation analysis method for low-level radioactive wastewater

There is currently general concern over low-level radioactive wastewater from the development of
nuclear industry. In this paper, a method based on an ultralow-level liquid scintillation
spectrometer for measuring uranium radioactivity in low-level radioactive wastewater is proposed.
This method can easily and quickly measure the radioactivity level of uranium in samples and can
even distinguish the main isotopes of uranium. The liquid scintillation method directly provides
results in units of radioactivity activity concentration, which are more convenient for comparison
with relevant national standards to determine whether the emission standards are met. The lowest
limit of detection of this method is 0.014 Bq l −1 within 600 min.
