Does uranium cause lung cancer?
We found strong evidence of an increased risk for lung cancer in white uranium miners. The risk was 6 times greater than normal in white miners (about 64 expected, 371 seen). This was mainly due to exposure to radon gas or its decay product, radon daughters, in the mines.
What happens if you are exposed to uranium?
Due to the fact that uranium is a heavy metal, and is radioactive, exposures can lead to short-term or long-term side effects. If you have had significant exposure to uranium, you may be at risk for kidney disease, and/or bone or lung cancer. Urine and blood tests can help determine if you have been exposed to uranium.
Is it safe to mine uranium?
Although uranium itself is barely radioactive, the ore which is mined must be regarded as potentially hazardous due to uranium’s decay products, especially if it is high-grade ore. The gamma radiation comes principally from isotopes of bismuth and lead in the uranium decay series.
Can uranium cure cancer?
The Actinium-225 present in the Uranium-233 can be extracted and used in therapies to treat certain forms of cancer, like Acute Myeloid Leukemia, with extraordinary results.
What food has uranium in it?
For most people, food and drinking water are the main sources of uranium exposure. Root crops such as potatoes, parsnips, turnips, and sweet potatoes contribute the highest amounts of uranium to the diet.
Can touching uranium harm you?
Because uranium decays by alpha particles, external exposure to uranium is not as dangerous as exposure to other radioactive elements because the skin will block the alpha particles. Ingestion of high concentrations of uranium, however, can cause severe health effects, such as cancer of the bone or liver.
Why is uranium so toxic?
Several possible health effects are associated with human exposure to radiation from uranium. Because all uranium isotopes mainly emit alpha particles that have little penetrating ability, the main radiation hazard from uranium occurs when uranium compounds are ingested or inhaled.
Which country is rich in uranium?

What is uranium made out of?
Uranium occurs naturally in several minerals such as uranite (pitchblende), brannerite and carnotite. It is also found in phosphate rock and monazite sands. World production of uranium is about 41,000 tonnes per year. Extracted uranium is converted to the purified oxide, known as yellow-cake.
