Thorium vs Uranium

Wales [Received 19 September 1963) Abstractarboniferous black shales from the Lower and Middle coal measures of the South Wales Coalfield have been analysed for uranium, thorium, potassium and carbon. In the 32 samples investigated the average values for uranium and thorium are 4-0 and 12-3 ppm respec- tively, and the Th/Y ratio 3-2.
