This study aims to analyse the radioactivity data of soil samples from Tiruvannamalai District of Tamilnadu, India using statistical methods. Statistical analysis is applied on 63 samples for measuring gamma emitting radionuclides (238U, 232Th &40K) and calculating radiation hazard indices. In this work conventional statistical analysis (Basic statistics and Frequency histogram) and multivariate statistical analysis (Pearson’s correlation coefficient analysis, Factor analysis and Cluster analysis) are employed. This analysis is also helpful to identify the existing relationships between the radiological hazard parameters and radionuclides, and consequently assessing the health exposure implications of the public to the studied soil. The results show that there is no potential radiological health hazard associated with the soil samples of the study area.
