Distribution and disequilibrium of natural radionuclides in the black shale from Wadi Naseib area, Southwest Sinai, and their environmental hazard indices
Several radionuclides of the 238U (or its decay daughters such as 234Pa, 234U, 230Th, 226Ra, 214Pb, and 214Bi), 232Th (228Ac, 208Tl, and 212Bi), and 235U decay series have been measured. The 234U/238U activity ratios (ARs) are >1 for most rock samples indicating preferential abundance of 234U rel...
