Assessment of 238U, 232Th, 40K and heavy metals in soil samples of near Shivalik Hills and origin of Saraswati River, Yamuna Nagar of Haryana, India
摘要
The main goal of the study is to evaluate the activity level of gamma radiation from uranium (238U), thorium (232Th) and potassium (40K) using gamma spectrometry with NaI(Tl) detector and concentration of heavy metals (HM), i.e. lead (Pb), cadmium (Cd), nickel (Ni), cobalt (Co), iron (Fe) and chromium (Cr) using atomic absorption spectroscopy (AAS) in soil samples taken from different places of Saraswati River, Yamuna Nagar, Haryana in India. The mean value of 238U, 232Th, 40K, radium equivalent activity and air-absorbed dose rate lies within the safe limit. The mean value of Radium equivalent activity and air-absorbed dose rate is within safe limits. The mean value of the corresponding HM is Fe > Pb > Ni > Co > Cd > Cr. The findings indicate that the level of HM in the soil sample of the study area is considerably below the acceptable limit.
