For the rock samples from hilly area, the corresponding concentrations were much higher as 18.7–4023, 0.902–173, 9.58 × 10 –5 –1.29 × 10 –2 , and 18.8–2279 Bq kg −1 , but the 236 U/ 238 U atom ratios were in the same range of (1.52–3.04) × 10 –8 , indicating the 236 U was primarily due to the natural nuclear reactions.}, pages = {103--111}, title = {First study on 236U in environmental samples from Bangladesh by ICP-MS/MS prior to the operation of its first nuclear power plant}, volume = {330}, year = {2021} }
