DH-la : a certified uranium-thorium reference ore / by H. F. Steger, W. S. Bowman and G. Zechanowitsch.: M38-13/81-11E-PDF

"A 122-kg sample of a uranium-thorium ore, DH-la, from Elliot Lake, Ontario, was prepared as a compositional reference material to replace the similar certified ore, DH-1, of which the stock had been exhausted. DR-la was ground to minus 74 11M, blended in one lot and bottled in 200-g units. The homogeneity of DH-la with respect to uran-ium was confirmed in CANMET using the volumetric-umpire method. The recommended value for uranium is based on the data from the confirmation of homogeneity. For thorium, twelve laboratories provided results in a "free-choice" analytical program. A statistical analysis of the data gave a recommended value of 0.263% for uranium and 0.091% for thorium"--Synopsis, p. i.
