Abstract

After the Chernobyl accident in April 1986 the 134Cs, 137Cs and 40K activity of mushrooms of different genera and their corresponding soils from woods located in the province of Umbria (Italy) was determined. The results indicated: a temporally increasing trend for 137Cs up to a "limit value" depending on local fallout in 1986; different cesium concentrations in various mushroom genera; and uptake of potassium from soil that did not appear to compete with cesium uptake. No reliable correlation can be inferred between the cesium content of the soil and those of mushrooms.

摘要

1986年4月切尔诺贝利事故发生后，对意大利翁布里亚省树林中不同属蘑菇及其相应土壤的¹³⁴Cs、¹³⁷Cs和⁴⁰K活度进行了测定。结果表明：¹³⁷Cs活度呈随时间上升趋势，直至取决于1986年当地沉降物的“极限值”；不同蘑菇属中铯浓度不同；土壤中钾的吸收似乎不与铯的吸收竞争。无法推断出土壤铯含量与蘑菇铯含量之间存在可靠的相关性。
