What causes radon gas exposure?
Radon is a radioactive gas formed when uranium deep underground begins to break down. It makes its way up to the ground level where it usually dissipates into the atmosphere. However, our homes – and particularly our basements – can attract and collect radon gas, where it can then build up into toxic levels.
Where does radon come from naturally?
Radon is a natural radioactive gas which comes from the decay of uranium in rocks and soil. It is colourless, odourless and tasteless. In outside air the levels of radon are low but it collects in enclosed places, such as houses, workplaces and other buildings.
Why does radon gas accumulate in basements?
Radon gas accumulates in basements because of low ventilation. Heating and air-conditioning, natural air movement, the “stack effect,” as well as diffusion of radon gas through the floors and walls distribute radon throughout the house.
Do all houses have radon?
Remember all homes have radon gas in them. Where a high radon level is detected, it can be successfully lowered at a cost which is usually small when compared to the value of the house. When a high radon level is found, fixing the problem can help protect the value of your home.
Where does radon come from in homes?
Radon is a radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up.
How is radon formed in homes?
Radon comes from the breakdown of naturally-occurring radioactive elements (such as uranium and thorium) in soils and rocks. The gas moves up through the soil to the surface, where it can enter homes, schools and the workplace through cracks and other holes in the foundation.
How does radon accumulate?
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 can accumulate in buildings and, over time, can pose a serious health hazard.
Does radon come up from basement?
Radon comes from decaying Uranium that is contained in the rock and soil beneath the basement (under the foundation) of every home. Being in constant contact with the ground, a home’s basement is the main entry point for Radon gas. Conditions inside your basement can contribute to the radon level as well.
