Radioactivity Levels, Spatial Distribution, and Radiological Risk Assessment of ²²⁶Ra, ²²⁸Ra, ⁴⁰K, and ³H in Water Samples from Dhaka City and Savar, Bangladesh.

ABSTRACT: This investigation was conducted to measure the radioactivity levels of ²²⁶Ra, ²²⁸Ra, ⁴⁰K, and ³H in the 13 most popular branded bottled mineral water (BMW), 12 groundwater sources consumed in Dhaka city, Bangladesh, and six water samples collected from the nuclear object site at Savar, adjacent to Dhaka. The activity of ³H was measured by using a liquid scintillation counter, and a gamma-ray spectrometer with an HPGe detector was used to measure the activity of other radionuclides. The average activity concentrations of ²²⁶Ra, ²²⁸Ra, ⁴⁰K, and ³H in BMW samples and groundwater were found to be 1.81 ± 0.43, 1.74 ± 0.40, 43.08 ± 6.23, 2.42 ± 0.16, and 1.61 ± 0.51, 1.69 ± 0.45, 57.42 ± 3.16, and
