Radon - Wikipedia
WEBRadon is produced by the radioactive decay of radium-226, which is found in uranium ores, phosphate rock, shales, igneous and metamorphic rocks such as granite, gneiss, and schist, and to a lesser degree, in common rocks such as limestone.
Radon - World Health Organization (WHO)
WEBJan 25, 2023 — Radon is a radioactive gas that has no smell, colour or taste. Radon is produced from the natural radioactive decay of uranium, which is found in all rocks and soils. Radon can also be found in water.
What is Radon? | US EPA - U.S. Environmental Protection Agency
WEBDec 20, 2023 — Radon is a radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes.
Radon and Your Health | Radon | CDC - Centers for Disease …
WEBFeb 16, 2024 — Radon is an odorless and invisible radioactive gas naturally released from rocks, soil, and water. Radon can get trapped inside homes and buildings, and build up in the air. Over time, breathing in high levels of radon can cause lung cancer.
Radon Gas: What Is It, Detection & Complications - Cleveland Clinic
WEBApr 30, 2021 — Radon gas forms naturally when radioactive metal (radium, thorium or uranium) breaks down in rocks, soil or groundwater. It evaporates and disappears outdoors, so levels outside are low. Indoors, however, radon gas can enter buildings through their foundations and become trapped.
Radionuclide Basics: Radon | US EPA
WEBMay 6, 2024 — Radon (chemical symbol Rn) is an odorless, colorless, radioactive gas. It comes from the natural decay of uranium and radium found in nearly all rocks and soils. Radon can move up from the ground into buildings through openings in floors or walls that are in contact with the ground.

Radon and Cancer - NCI - National Cancer Institute
WEBDec 6, 2011 — Radon decays quickly, giving off tiny radioactive particles. When inhaled, these radioactive particles can damage the cells that line the lung. Long-term exposure to radon can lead to lung cancer, the only cancer proven to be associated with inhaling radon.
What is radon gas? Is it dangerous? | Radiation Protection - US EPA
WEBAug 21, 2019 — Radon is a naturally-occurring radioactive gas that can cause lung cancer. Radon gas is inert, colorless and odorless. Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces.
