Uranium and thorium minerals contain radon.
Radon is a progeny of uranium, as a radioactive decay element, independently of the uranium quantity or concentration.
Radon comes from the soil. It occurs naturally from decaying uranium.
Radon is a radioactive gas in the decay series of uranium and thorium.
Uranium minerals like uraninite and pitchblende are known to contain radon gas. These minerals release radon as they decay and break down. Radon is a radioactive gas that is invisible, odorless, and tasteless, and can be harmful if inhaled in high concentrations.
Risks are evaluated by the strict control of the concentrations of radon in uranium in atmosphere, waters, soils, vegetation.Uranium is toxic and radioactive and radon is radioactive.
It comes from the breakdown of uranium.
This gas is radon (Rn).
Radon gas is produced from the natural decay of uranium in soil, rocks, and water. When uranium breaks down, it forms radium, which then decays to produce radon gas. Radon can seep into buildings through cracks in the foundation or gaps in walls and floors.
For example lung cancers, from uranium (and the daughters radium and radon).
Radon gas comes naturally from soil form decaying uranium deposits.
Radon is a natural chemical element; it can be found in the radioactive decay series of uranium and thorium.
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.
