Abstract

In the present investigation, the concentration of 210Po was measured in soil and sediment samples from riverine environment of Hemavathi river of south Karnataka. The 210Po in the samples was separated by radiochemical method, and the activity was counted using ZnS(Ag) alpha counter. Seasonal variation of 210Po was studied for soil and sediment samples. The mean activity of 210Po in monsoon was higher than that in pre-monsoon samples. The granulometric contents (sand, silt and clay), organic matter and pH contents were measured in soil, and sediment, respectively. The organic matter content and clay positively correlated with 210Po activity. There is a good correlation between activity concentration of 210Po and organic matter in both monsoon and pre-monsoon samples. Using the SPSS 22 statistical software, the median, skewness, kurtosis, variance and frequency distribution were calculated.
