Investigations conducted during the GEOSECS program concluded that radium-226 (T 1/2 = 1602 y) and barium are tightly correlated in waters above 2500 m in the Atlantic, Pacific and Antarctic Oceans, with a fairly uniform 226 Ra/Ba ratio of 2.3 ± 0.2 dpm µmol -1 (4.6 nmol 226 Ra/mol Ba). Here, we rep...
