Determination of activity concentration of 238U and 232Th series radionuclides in soil using a gamma-ray spectrometer in singles and coincidence modes

Automated method for concurrent determination of thorium (230Th, 232Th) and uranium (234U, 235U, 238U) isotopes in water matrices with ICP-MS/MS

“…Therefore, the measurements of thorium and uranium in environmental matrices in combination with other naturally occurring radionuclides (i.e., 40 K, 210 Po) are requisite for radiation assessment and environmental monitoring. 4 Moreover, both thorium and uranium are important actinides in the nuclear fuel cycles. For example, both of them could be used as raw irradiation materials for the preparation of other radionuclides and are recovered in the spent fuel reprocessing.…”
