粘附到植物表面的放射性污染的土壤对人的食入内照射剂量有一定的贡献。本文建立了一种用于测量植物表面土壤粘附量的￣（１３７）Ｓｃ中子活化分析方法，其测量下限为０．０５ｍｇ（干土）／ｇ（干植物）。实验研究了黑麦草（ＬｏｌｉｕｍＰｅｒｅｎｎｅＬ．）和蚕豆（ＶｉｃｉａＦａｂａＬ）的土壤质量沉积，分别估算了雨洗（Ｒａｉｎｓｐｌａｓｈ）和风蚀（Ｗｉｎｄｅｒｏｓｉｏｎ）对土壤质量沉积的贡献。在实验田条件下粘附到植物表面的土壤量测量值分别为：黑麦草，５．７７±１．４４ｍｇ（干土）／ｇ（干植物）；蚕豆，９．５１±０．７３ｍｇ（干土）／ｇ（干植物）。雨洗和风蚀对植物表面土壤质量沉积的贡献估算值（在实验期间）对黑麦草分别是４７％和５３％，对蚕豆分别是６８％和３２％。现场研究表明，粘附到植物表面的土壤量可以对植物￣（１３７）Ｃｓ污染产生高达２３％的贡献份额；经土壤质量沉积修正的￣（１３７）Ｃｓ土壤－植物转移参数，随土壤中￣（１３７）Ｃｓ含量和植物表面土壤粘附量不同而程度不同地下降。
Radioactively contaminated soil adhering to the plant surface contributes to the human ingestion dose. A 137C neutron activation analysis method was developed for the measurement of soil adhesion on plant surfaces with a lower limit of measurement of 0.05 mg (dry soil) per gram of dry plant. The soil quality of Lolium perenne L. and Vicia faba L was studied experimentally, and the contributions of Rainsplash and Winderosion on the deposition of soil quality were respectively estimated. The amount of soils adhering to the plant surface under experimental field conditions were: ryegrass, 5.77 ± 1.44 mg (dry soil) per g (dry plant); broad bean, 9.51 ± 0.73 mg Soil) / g (dry plant). The estimated contribution of rainwater and wind erosion to the deposition of soil quality on plant surfaces (during the experiment) was 47% and 53% for ryegrass and 68% and 32% for broad bean respectively. Field studies have shown that the amount of soil adhering to the surface of plants can contribute up to 23% of the contribution of plant 137Cs contamination; the soil-plant 137Cr-soil transport parameters corrected for soil quality deposition vary with soil (137) Cs content and plant surface soil adhesion amount varies with different degrees of decline.
