Uranium isotopes are radioactive.
This process, known as radioactive decay, generally results in the emission of alpha or beta particles from the nucleus. It is also often accompanied by emission of gamma radiation, which is electromagnetic radiation like X-rays. The major health effect of exposure to uranium is cancer. It is suspected of causing lung cancer and tumors in the lymphatic and bone tissues.
