so that means that of 801 TONS of uranium, 795 tons or so will be U238.
in any event your point is exactly valid that buring coal releases orders of magnitude more radioactivity into the environment than commercial nuclear power generation (for example) - check out this article:
http://www.ornl.gov/info/ornlreview/rev26-34/text/colmain.htmlBased on the predicted combustion of 2516 million tons of coal in the United States and 12,580 million tons worldwide during the year 2040, cumulative releases for the 100 years of coal combustion following 1937 are predicted to be:
U.S. release (from combustion of 111,716 million tons):
Uranium: 145,230 tons (containing 1031 tons of uranium-235)
Thorium: 357,491 tons
Worldwide release (from combustion of 637,409 million tons):
Uranium: 828,632 tons (containing 5883 tons of uranium-235)
Thorium: 2,039,709 tons
for comparison purposes, the amount of uranium released in iraq through weapons use that everyone's screaming about is 320 tons - or about 0.04% that's been released through coal burning in the USA - where's the outrage?
