Abstract |
|
|
| A study on radon and thoron exhalation rate measurements in beach sand samples collected along east coastal region of Tamil Nadu, India, at 45 locations are carried out. Activity concentration of 238U and 232Th are determined in the collected samples by subjecting it into gamma spectrometry. Radon/thoron exhalation rates are measured by employing, portable radon/thoron monitor, RAD 7. Thoron exhalation rate is found to be high in comparison with radon exhalation rate at many locations due to high 232Th deposits along east coastal region. This work presents a comprehensive measured data on of 238U and 232Th radionuclides distribution and radon and thoron exhalation rate from sand samples collected in the study region. |
