Analysis of uranium and radon concentration in water of north-west Punjab, India

The uranium (²³⁸U) and radon (²²²Rn) concentrations have been assessed in drinking water samples from north-west Punjab, India. LED Fluorimetry technique is used for the measurement of uranium and degassing technique with scintillation based radon monitor (SRM) is used for radon measurements. The ²³⁸U and ²²²Rn concentration values in water are found in the range of 1.2 ± 0.3–59.32 ± 2.9 µgl⁻¹ and 0.75 ± 0.08–7.25 ± 0.52 Bql⁻¹ respectively. The uranium and radon values in present study mostly lies within the safe limit and the calculated annual dose values are also below the prescribed dose limit of 100 µSvy⁻¹.
