江苏省句容地区~(137)Cs背景值研究
Study on Reference ~(137)Cs Inventory of Jurong Region in Jiangsu Province
摘要
Abstract
Soil erosion is one of the primary environment problems in today's world, and ~(137)Cs tracing technology is a mature method in studying soil erosion. It is vital to confirm the reference ~(137)Cs inventory. The paper, giving a new method for determining the reference ~(137)Cs inventory of soil in the region where lacks the perfect reference sample sites, studied the characteristic of ~(137)Cs soil profile distribution and the increase of the number of the soil samples, by comparing with the other's studies, the determined soil reference ~(137)Cs inventory was 1 820.36 Bq/m~2 in Jurong region, Jiangsu Province. This reference inventory was close to the value nearby Jurong region in Jiangsu Province, so the activity was reliable and may be used to estimate the loss rate of soil and the load of agricultural non-point contamination.关键词
