We need the isotope uranium-235 in a concentration near to 99 % ! Only this isotope is fissile. Also the uranium will be very pure and in a sufficient quantity to form the critical mass, etc.
Lead is always present in uranium-bearing rocks because lead is a decay product of uranium. As uranium undergoes radioactive decay, it transforms into different elements, including lead. This is a natural process that occurs over time in the rocks containing uranium.
It is a naturally occurring isotope of Uranium making 0.72% of total naturally found Uranium. Since, it is very less in nature, therefore it is sometimes made from Uranium-238 in nuclear reactors.
Radon is a naturally occurring radioactive gas that is produced from the decay of uranium in soil and rocks. It is found in the Earth's crust and can seep into buildings through cracks and openings in the foundation. This is why radon is still present in nature.
URANIUM (:
The nuclear reaction that occurs when a uranium nucleus breaks up into fragments is called nuclear fission. It releases a large amount of energy in the form of heat and radiation.
Polonium is a very rare chemical element accompanying uranium in ores (probably in the form of an oxide).
Lead is always present in uranium-bearing rocks because lead is a decay product of uranium. As uranium undergoes radioactive decay, it transforms into different elements, including lead. This is a natural process that occurs over time in the rocks containing uranium.
It is a naturally occurring isotope of Uranium making 0.72% of total naturally found Uranium. Since, it is very less in nature, therefore it is sometimes made from Uranium-238 in nuclear reactors.
Uranium because uranium has the highest atomic number, 92, of the natural, actinide elements. Elements higher than 92 are man-made elements. Check the periodic tables to see for yourself!~
In such a case nuclear fission occurs.
Radon is a naturally occurring radioactive gas that is produced from the decay of uranium in soil and rocks. It is found in the Earth's crust and can seep into buildings through cracks and openings in the foundation. This is why radon is still present in nature.

corruption occurs because it is human nature to take the easy way out
Uranium is the heaviest naturally occurring actinide.
