Abstract
Six representative deep sea cores have been analyzed for their thick source alpha emission at about every 20 cm. Some correlation can be made with a calcium carbonate content but not with absolute surface area. The range of relative alpha activity is 2-3 counts/cm2/hr for sand, 2--4 for globigerina ooze, 4-6 for foraminiferal green clay, and 5-10 for fine white to red clay with low foram content. It appears that total alpha activity cannot be correlated simply with age as might be suggested from the Urry ionium vs. depth curves.
