Influence of physico-chemical parameters on natural radionuclides in the coastal belt of Kollam district, South west coast of India
摘要
The present investigation assessed the influence of physico-chemical parameters on natural radionuclides in the Kollam coastal belt which is a high background radiation region. The activity concentration of 40K, 226Ra, and 232Th in sand samples has been measured using Flat type 5" × 5" NaI detector to assess the influence of physico—chemical parameters in natural radionuclides. The physico-chemical parameters such as moisture content, pH, electrical conductivity, organic matter content, and particle size distribution percentage (silt, clay, and sand) of sand samples were determined using standard procedures and techniques. The measured activity concentration was then correlated with the physico-chemical parameters of the sand samples and possible conclusions were drawn.
