This method describes the analysis of 234Th in 30L seawater samples. The document was produced by A.P. Fleer and M. Bacon at Woods Hole Oceanographic Institution, 1980.
The procedure involves acidification of samples which are then processed through a series or ion exchange columns for sample purification. Samples are eventually silver plated and counted by alpha spectrometry.
