Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold.[1] It can be found almost everywhere in rock, soil, rivers, and oceans.[2] The challenge for ...

Decay rate of uranium-235 alone. The 1.000 gram of uranium contains 0.0072 gram of uranium-235. Uranium-235 has a half-life of 704 million years. Let's convert that to seconds: (704 x 10 6 years) x (365.25 days/year) x (24 hours/day) x (60 minutes/hour) x (60 seconds/minute) = 2.22 x 10 16 seconds.
