Abstract
The present study evaluates the radiological indices due to naturally occurring radionuclides (238U, 232Th and 40K) present in surface soil samples of Indian Sundarbans. Univariate and multivariate statistical analysis were carried out to understand the probability distribution of the radionuclides, correlate and classify the different radiological parameters. Averages of absorbed dose rate (D), annual effective dose were found higher than world averages, whereas that of radium equivalent activity (Raeq), annual gonadal dose equivalent and hazard indices (Hin and Hex) were found below the maximum permissible limit. The data indicates that Indian Sundarbans poses no significant radiological health hazards.
