Abstract: Total alpha and gamma spectrum analysis were performed on a sample of uranium-containing radioactive wastewater, and the feasibility of measuring uranium-containing radioactive wastewater by gamma spectrometry was verified. It shows that, with this method, the efficiency can be effectively improved for the emergency monitoring of total radioactivity in uranium-containing radioactive wastewater. The selection of monitoring equipment suitable for the nuclides in the sample to be tested can effectively shorten the measurement time and improve the measurement accuracy.

Key words: Gamma spectrometry, Uranium-containing radioactive wastewater, Emergency monitoring
