Abstract
MEASUREMENTS carried out in the Oceanographical Institute, Göteborg, on the radium content in deep-sea cores by H. Pettersson, Traude Bernert, V. Kröll1 et al. showed the vertical distribution of radium to be highly complicated. We were therefore asked to develop a method for direct measurement of the ionium content in samples of sediment from the Swedish Deep-Sea Expedition.
