Where can radon-222 be found?
Radon can enter a home any place it finds an opening where the house is in contact with the ground: cracks in foundation walls and in floor slabs, construction joints, gaps around service pipes, support posts, window casements, floor drains, sumps or cavities inside walls.
Is radon-222 odorless?
Radon (Rn-222) is an odorless and colorless natural radioactive gas. It is produced during the radioactive decay of radium-226, itself a decay product of uranium-238 found in many types of crustal materials, that is, rocks and soils.
Is radon colorless and odorless gas?
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.
What causes radon-222?
Thus, 222Rn is a carcinogen; in fact, it is the second leading cause of lung cancer in the United States after cigarette smoking, with over 20,000 deaths per year attributed to radon-induced lung cancer.
What does the 222 in radon-222 represent?
Radon-222 atom is a radon atom. Radon is a naturally occurring radioactive gas that is odorless and tasteless. It is formed from the radioactive decay of uranium. Uranium is found in small amounts in most rocks and soil….4.3Related Element.

What is radon-222 used for?
It is chemically inert, but radioactive. Radon decays into radioactive polonium and alpha particles. This emitted radiation made radon useful in cancer therapy. Radon was used in some hospitals to treat tumours by sealing the gas in minute tubes, and implanting these into the tumour, treating the disease in situ.
What is a colorless odorless poisonous gas?
Carbon Monoxide is a colorless, odorless, tasteless, highly toxic gas that is undetectable to the human senses.
What type of gas is radon?
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.
What type of radiation is radon-222?
radon-222, with a half-life of 3.825 days, emits an alpha particle to become polonium-218. polonium-218, with a half-life of 3.05 minutes, emits an alpha particle to become lead-214.
What does radon-222 look like?
How did radon 222 become a respiratory carcinogen?
Radon-222, a noble gas resulting from the decay of naturally occurring uranium-238, is the first occupational respiratory carcinogen to have been identified. As early as the 1500s, Agricola chronicled unusually high mortality from respiratory disease among underground metal miners in the Erz Mountains of eastern Europe ( Hoover and Hoover 1950 ).
Where can radon gas be found in the atmosphere?
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.
What kind of cancer can radon gas cause?
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.
How is radon gas fixed in a building?
Usually, radon problems are fixed using an underground ventilation system or by increasing the rate of air changes in the building. For more information about indoor air quality and the health risk of radon, visit Health Risk of Radon.
