It is legal to have uranium and thorium compounds listed on a permit but they still count towards the 5 kg limit for exemption. Above a total of 5 kg of uranium and thorium, they all need permitting. Some current permits may include uranium and thorium which can be exempt and these continue in

Some secondary uranium deposits are thought to have formed from uranium derived by the weathering of silicic igneous rocks such as granites, rhyolites, and tuffs. A regional geochemical survey was made to determine the distribution of uranium and thorium in granitic rocks of the Basin and Range province in order to evaluate the potential for secondary uranium occurrences in the area

The substitution of thorium for uranium as fuel in nuclear reactors has significant potential for minimizing both problems. ... 232 performs this function by transmuting into uranium-233 permitting reactor energy by fission. As do other fertile materials, thorium-232 requires a source of neutrons for the transmutation

Aug 03, 2020 Ceramic materials such as tiles or pottery often contain elevated levels of naturally occurring uranium, thorium, or potassium. Some pre-1960 tiles, pottery, and ceramics—especially those with an orange-red glaze such as Fiestaware –are radioactive due to the uranium in the glaze

This will permit the average terrestrial concentrations of uranium and thorium to be 2 to 4.7 times higher than that observed in chondrites. The resulting models of the terrestrial heat production will be considerably different from those for chondritic heat production because of the longer half-life of U(238) and Th(238) compared with K(40)
