Objective To optimize the conditions for the determinationof total $\alpha$ and total $\beta$ radioactivity in drinking water andimprove the accuracy of the experiment. Methods On the basis ofmeasuring the residue content in drinking water, the total $\alpha$ and $\beta$ radioactivity values in drinkingwater were determined by improving evaporation and concentration processand optimizing reagent conditions. Results In this study, the amount ofresidue, $\alpha$ and $\beta$ radioactivity increased, and thetest time was reduced compared with the traditional method. Conclusion The method significantly improves the accuracy of results and testingefficiency and can be further optimized. It provides certain researchsignificance in the quality control of laboratory measurements.
