Radon is a radioactive gas that forms naturally when uranium thorium or radium which are radioactive metals break down in rocks soil and groundwater.
Radon in air. Radon is a naturally occurring radioactive gas that is released from the ground and is present everywhere. Radon is a highly toxic naturally occurring gas. The Environmental Protection Agency EPA recommends buildings be fixed if the radon level is 4 pCiL pico Curies per Liter or greater.
However background levels of radon in outdoor air are generally quite low about 0003 to 26 picocuries of radon per liter of air 2. Above this level a homeowner should take some remedial action to reduce the radon present in the air. The chart below provides more information.
While not a health based standard this level is a guideline for people to use in assessing the seriousness of their exposure. About 22000 deaths a year in the US. To make things worse its tasteless odorless and invisible.
Testing is the only way to know your level of exposure. Since you cant detect it. Radon in indoor air is the second leading cause of lung cancer.
Also your risk of developing radon-related lung cancer increases with higher levels of radon exposure. The lower the average pCiL level in the air you breathe the lower your risk of getting lung cancer. Radon gas is commonly found in the indoor air of homes and buildings.
Radon is measured in units of picocuries per liter pCiL of air. Radon in Air Radon is a radioactive gas which occurs in nature as a result of the radioactive decay of uranium. Zero would be the natural answer except that radon is a naturally occurring radioactive gas that is in the air all around us.
Are caused by breathing radon in indoor air. It is unavoidable hence the need for a radon detector as its colorless odorless and invisible only through monitoring will you be aware of the levels in the air. This gas is radioactive in nature and is one of the major causes of lung cancer in the USA.
Its mainly found in rocks and soil but can escape into water and air. Radon gas is one of the indoor pollutants that may be presence in your house. When radon gas decays it emits radioactive radiation in the form of an alpha particle.
Depending on your geographic location the radon levels of the air you breathe outside of your home may be as high as 075 pCiL. Radon levels in the outside air are also very low as radon leaving the soil quickly mixes with the general atmosphere. Radon is one link in the decay chain of uranium.
The WHO guidelines for drinking water quality 2011 recommend that screening levels for radon in drinking-water be set based on the national reference level for radon in air. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes. Protection Agency USEPA has set a radon in air Action Level of 40 pCiL for radon gas in indoor air.
Radon dissolved in drinking-water is released into indoor air. The national average of outside radon levels is 04 pCiL and it is estimated by the National Academy of Sciences that outdoor radon levels cause approximately 800 of the 21000 radon. The USEPA also states that with a radon in air level between 20 pCiL and 39 pCiL mitigation should be considered.
You cant see or smell radon. This is why radon levels in lakes and rivers are low. It comes from the natural breakdown of uranium in soil rock and water and gets into the air you breathe.
Radon typically moves up through the ground to the air above and into your home through cracks and other holes in. Radon daughters are often attached to dust and you are exposed to them primarily through breathing 2. This radioactive particle is made up of two protons and two neutrons.
Normally a higher radon dose is received from inhaling radon compared with ingestion. Outdoor radon levels in the UK are low typically a few Becquerels per cubic metre of air. This is how radon becomes extremely dangerous.
You cannot see it smell it or taste it. Radon is a radioactive gas that has been found in homes all over the United States. Radon is a naturally occurring radioactive gas that can cause lung cancer.
Radon is a form of ionizing radiation and a proven carcinogen. Where ground water comes to the surface it begins to lose radon to the air. Radon can be found in high concentrations in soils and rocks containing uranium and in water from residential wells.
EPA recommends taking action to reduce radon in homes that have a radon level at or above 4 pCiL of air. Breathing radon in the indoor air of homes contributes to about 15000 lung cancer deaths each year in the United States and 1100 in the UK HPA. They are present in nearly all air.
Radon gas is a naturally-occurring byproduct of the radioactive decay of Uranium in the soil. In circumstances where high radon concentrations might be expected. The Environmental Protection Agency of the United States estimates that there are 21000 deaths each year due to lung cancer caused by this gas.
Indoor radon levels vary across the UK from less than ten to thousands of Becquerels per cubic metre of air. Depending on the country acceptable radon levels vary.
