WebUranium is a common, naturally occurring element, present in low amounts in rocks, soil, air, surface water and groundwater. Uranium is naturally radioactive, like many other naturally occurring radioactive elements in nature. Natural uranium exists as a mixture of three types, or isotopes, called U-234 ( 234 U), U-235 ( 235 U), and U-238 ( 238 U). WebWhy Some Natural Gas Contains Helium. Most of the helium that is removed from natural gas is thought to form from radioactive decay of uranium and thorium in granitoid rocks of the basement rock below the gas field. As a very light gas, it is buoyant and starts rising upwards as soon as it forms.
