A Quantitative Study of Natural Uranium Present in Groundwater of Tiruvannamalai District of India

摘要

Uranium concentration in the groundwater samples from the district of Tiruvannamalai, Tamil Nadu, was measured using an LED fluorimeter. Grid sampling technique was used for the collection of water in the study area. The basic physical parameters of water such as EC, TDS and pH were also determined and their levels have been compared with standard limits. All the samples qualified as potable water from the radiological perspective. Though some samples showed mild chemical toxicity they are still safe for ingestion. Different risk coefficients were calculated and they were compared with recommended safety limits specified by various agencies. Software tools such as QGIS 15 and Surfer 15 were employed for developing maps and plots.
