Abstract |
|
|
| Quantification of naturally occurring radioactive elements has been performed along the beach areas of Andhra Pradesh. The concentration of radio elements 238U, 232Th and 40K is estimated with the help of High Purity Germanium detector (HPGe). The average activity concentration of 238U and 232Th is 6 and 18 times higher than the prescribed value of UNSCEAR report. The calculated absorbed dose rate, annual effective dose rate, radium equivalent, hazard index, gamma index and alpha index also shows a higher than prescribed value. The thorium concentration and the absorbed dose rate values shows an increasing trend towards the northeast along the beach area. The average Th/U values are almost 4.5 times higher than the crustal ratio. Considering the tourism industry surrounding the study area based on the picturesque beaches and the heritage Buddhist stup a sites an estimation of the radioactive hazard index of the area must be known. |
