供测量比对用土壤放射性样品的制备和应用

Abstract

Abstract: This article summarized the preparation process and intercomparison results of the simulated environmentalradioactive soil samples. The components of the matrix were:SiO₂, Al₂O₃, Fe₂O₃, MgO, CaO, NaCl, KCl and TiO₂. All of the components were milled, oven-dried, sieved and then blended together. The homogeneity test was according to GB 15000.5—1994, and no significant differences were observed. The ³H analysis soils were spiked natural soils with the moisture content of 15%. Eight laboratories attended this intercomparison. The results proves that the preparation of the simulated soils were suitable for the inter-laboratories comparison.

Key words: simulated soil, intercomparison, environment, radioactive
