Thorium resources have not been estimated and assessed with a higher level of confidence, as in the case of uranium. Approximately 6 million tonnes of thorium have been estimated globally based on currently limited exploration and mainly on historical data. [4] [5] Thorium resources are found widely in over 35 countries all over the world.

Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
Monazite powder, a rare earth and thorium phosphate mineral, is the primary source of the world's thorium. India's three-stage nuclear power programme was formulated by Homi Bhabha, the well-known physicist, in the 1950s to secure the country's long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India.
Thorium concentrations on the Moon, as mapped by Lunar Prospector. Thorium is found in small amounts in most rocks and soils. Soil commonly contains an average of around 6 parts per million (ppm) of thorium. [1] Thorium occurs in several minerals including thorite (ThSiO 4), thorianite (ThO 2 + UO 2) and monazite. Thorianite is a rare mineral ...
The 2022 FIFA World Cup final was the final match of the 2022 FIFA World Cup, the 22nd edition of FIFA's competition for men's national football teams. The match was played at Lusail Stadium in Lusail, Qatar, on 18 December 2022, the Qatari National Day, and was contested by Argentina and defending champions France. With a record 1.5 billion ...
[39] [40] Ionium–thorium dating is a related process, which exploits the insolubility of thorium (both 232 Th and 230 Th) and thus its presence in ocean sediments to date these sediments by measuring the ratio of 232 Th to 230 Th. [41] [42] Both of these dating methods assume that the proportion of 230 Th to 232 Th is a constant during the ...
