Fractionation of 226Ra and Ba in the Upper North Pacific Ocean

open access: yesFrontiers in Marine Science, 2022
Investigations conducted during the GEOSECS program concluded that radium-226 (T1/2 = 1602 y) and barium are tightly correlated in waters above 2500 m in the Atlantic, Pacific and Antarctic Oceans, with a fairly uniform 226Ra/Ba ratio of 2.3 ± 0.2 dpm ...
