Abstract

Procedures have been developed for the analyses of dissolved and particulate ²³⁴Th, ²²⁸Th, ²³⁰Th and ²³²Th in seawater. Large volume samples (>1000 1) are collected using in situ pumps. Seawater is pumped sequentially through a filter cartridge and two MnO₂ adsorbers for the collection of particulate and dissolved Th, respectively. Both filters adsorbers are analysed for ²³⁴Th using a simple gamma counting technique. This newly developed ²³⁴Th procedure can be conducted at sea, and thus provides an easy and efficient method for ²³⁴Th analyses on large volume samples. Subsequent radiochemical purification procedures and low-level alpha counting techniques are used in the laboratory for the analyses of ²²⁸Th, ²³⁰Th and ²³²Th on these same samples.
