Concerns, Control and Remediation. The Complete Thorium Web Site. Information on Thorium and Thorium-related topics. Sponsored by Perma-Fix Environmental Services, Inc., www.perma-fix.com. Thorium is used in a wide array of products and processes, where its special properties make it useful when light or high temperature are involved. Handling and disposing of Thorium is a challenge, as it is radioactive and when it decays, and produces Radon gas (also historically called Thoron).

Thorium isomer lifetime measured! Thorsten schumm on 01.11.12 11:08 • No Comments. Bull; Write Comment. Looks like researchers are closing in on the elusive Thorium transition! A group from Los Alamos reports to have measured the lifetime of the isomer state. The lifetime of the isomer state would be 6(1) hours, the wavelength of the transition above 160 nm. This would indicate essentially no coupling between the nuclear dynamics and the electron shell. From our own experience we know, that it is very ea...

Element Thorium, Th, Actinide or Actinoid
Element Thorium, Th, Actinide or Actinoid. In 1815, Jons Jakob Berzelius, examining samples ores from mines of Fahlun (Falun) mines, Sweden, obtained a material which he hastily called thorium. It was done by Lars Frederik Nilson in 1882. Thorium. Is a member of actinide. Group of chemical elements. Isotope is the most long-lived and is found in nature. Its crustal abundance is 8×10. By mass. Around 120 thorium-containing minerals. Are known, the most important of which are thorite Th. Concentrated Trava...
