Web2 days ago · When Disneyland opened in Anaheim in 1955, the food offerings weren’t so different from what you’d find at a local county fair — hot dogs, fried chicken, barbecue and pancakes. That genre of food hasn’t disappeared — there’s always a wait for the incomprehensibly large and glistening turkey legs — but as Disney parks expanded across … Thorium-232 ( Th ) is the main naturally occurring isotope of thorium, with a relative abundance of 99.98%. It has a half life of 14 billion years, which makes it the longest-lived isotope of thorium. It decays by alpha decay to radium-228; its decay chain terminates at stable lead-208. Thorium-232 is a fertile material; it … See more The half-life of thorium-232 (14 billion years) is more than three times the age of the Earth; thorium-232 therefore occurs in nature as a primordial nuclide. Other thorium isotopes occur in nature in much smaller quantities … See more Thorium-232 has a half-life of 14 billion years and mainly decays by alpha decay to radium-228 with a decay energy of 4.0816 MeV. The decay chain follows the thorium series, … See more Thorium-232 is not fissile; it therefore cannot be used directly as fuel in nuclear reactors. However, Th is fertile; it can capture a neutron to form unstable Th . Th undergoes beta decay with a half-life of 21.8 minutes to Pa , which subsequently undergoes beta … See more
