摘要：
A method for determining the content of Po-210 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 Po-210 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.
