摘要：
A method for determining the content of 210Po in soil and sediment samples without the use of hydrofluoric acid has been developed. Soil and sediment samples were fused with sodium hydroxide and sodium peroxide to achieve a clear solution without any visible traces of the solid matrix. After extracting 210Po by spontaneous deposition from the sample, the sample was measured by alpha spectrometry. The average recovery for the method in environmental soil samples was 81.2 ± 6.0% and the detection limit of the method reaches 0.1 mBq/g.
