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.

使用LED荧光计测量了泰米尔纳德邦Tiruvannamalai地区地下水样品中的铀浓度。网格采样技术用于研究区域的水收集。还确定了水的基本物理参数，例如EC，TDS和pH，并将其含量与标准限值进行了比较。从放射学角度来看，所有样品均符合饮用水标准。尽管一些样品显示出轻微的化学毒性，但仍可安全摄入。计算了不同的风险系数，并将它们与各个机构指定的建议安全限值进行了比较。使用诸如QGIS 15和Surfer 15之类的软件工具来开发地图和绘图。
