URANIUM

Natural uranium occuring isotopes:Uranium 238Uranium 234Uranium 235

Uranium was discovered by Martin Heinrich, a German scientist n the mineral pitchblende (primarily mix of uranium oxides) in 1784Uranium isotpes were discovered by Arthur Jefferey in 1935

The half of Uranium 235 is 703.8 million years

Uranium isotopes are radioactive. The nuclei of radioactive elements are unstable, meaning they are transformed into other elements, typically by emitting particles (and sometimes by absorbing particles). This process, known as radioactive decay, generally results in the emission of alpha or beta particles from the nucleus.

-Scientists have detected no harmful radiation effects of natural levels of uranium.

Uranium 235 is the principal fuel contained in nuclear reactors and the main raw material used in nulcear weapons

Uranium 235

Nuclear Reactor

-chemical effects may occur after the uptake of large amounts of uranium and these can cause health effects such as kidney disease.-When people are exposed to uranium radionuclides that are formed during radioactive decay for a long period of time, they may develop cancer

-The first atomic bomb used in warfare was an uranium bomb.-Uranium can be found naturally in the environment in very small amounts in rocks, soil, air and water.
