Determination of Uranium, Thorium, and Ionium in sediment cores of the Caribbean and Ionian Sea, supplement to: Mangini, Augusto; Dominik, Janusz (1978): Th230-excess EDTA extraction: A modification of the ionium method for high accumulation rate determinations.

A rapid procedure for Io (Th230) dating of sediments with accumulation rates in the range of several cm/1000 years is described. Studying of large sample populations with very small Io-excess activity is possible as the counting time (around 1500 min/sample) are 2 to 5 times shorter than with the standard Io-excess method. Improved sensitivity of the Io-excess measurement is achieved by:
