Variations in uranium and thorium are described for Pennsylvanian high-volatile bituminous coals in Indiana. The average U concentration is 1.77 ppm and it ranges from 0.18 ppm to 17.0 ppm. The average Th concentration is 1.83 ppm, with a range of 0.28 ppm to 18.0 ppm. The coals have lower U and Th contents than associated clastic sediments. The contents of U and Th in fly ash generated from the Springfield and the Danville coals are about 20 ppm and 10 ppm, respectively. U and Th values in Indiana coals and their coal combustion products are low and should not cause concern of radiological risk. However, there is always the possibility of some local enrichment and therefore, their concentrations both in coal and coal combustion products should be monitored.
