- Vents must be above the roof surface.
- Vents must be 3 m or greater above the ground.
- If vents are not at least 0.6 m above windows, doors, or other openings that could allow radon to reenter the home, they must be at least 3 m away from such openings.

Will an air purifier remove radon?
Yes, air purifiers help with radon gas reduction to some extent. The air purifiers with activated carbon filter technology are highly effective in trapping radon gas.
Likewise, Can radon pipes run horizontally? If it terminates less than 10 feet horizontal distance below a window it could be a potential safety hazard. If it terminates less than 10 feet horizontal distance below a ventilated soffit or other air vent it could be a potential safety hazard.
Where is radon most prevalent? Radon gas is a ubiquitous element found in rock and soil. The burning of coal and other fossil fuels also releases radon. When radon escapes from soil or is discharged from emission stacks to the outdoor air, it is diluted to levels that are normally, but not always, lower than indoor air.
What season is radon highest?
To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.
What state has lowest radon levels?
Hawaii has the lowest radon levels of all 50 states, with an average level of 0 pCi/L.

What type of soil has the most radon?
Granitic type soils present higher levels of radon gas. Non-granitic soils have traditionally been considered to have very low radon levels.
Does a dehumidifier reduce radon?
No, buying a dehumidifier will not make radon go away. Research conducted by the US Environmental Protection Agency (EPA) has clearly disproved this idea.
How many radon sumps do I need?
1 sump per 250M2 of floor area. Use in conjunction with a radon membrane.
Does running HVAC reduce radon?
Based on the results it was concluded that an active ventilation system successfully reduces radon.
Does opening windows reduce radon?
As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.
Can blood test detect radon?
There are no symptoms, signs, or laboratory tests that are specific to radon poisoning. There are specialized tests that can detect radon in your urine, bones, and blood, but the results of these tests only tell if you were recently exposed to radon.
Are radon sumps noisy?
After a sump system has been installed, a radon measurement should be made to ensure that the radon levels have been reduced sufficiently. In most cases sump systems run relatively quietly, but sometimes noise is a problem. Noise is often due to air movement and not the fan.
Where does radon sump go?
A radon sump is a cavity about the size of a bucket immediately under the floor slab that is linked by pipe work to the outside. The radon rich air coming from the ground is drawn out from under the floor slab by a small electric fan in the pipeline and vented to outside before it is drawn into your home.
Can sump pump produce radon?
Can radon come from the sump pump or pit? Yes. Radon is a gas that enters your building from the soil beneath and around your house. These gases can enter your home through the footing drain tile that is connected to the sump pump in your basement.
Can radon go through concrete?
Radon, soil gasses, and water vapor will easily pass through any openings, cracks, gaps, drains, or thin concrete (rat slabs) in the basement.
Does a sump pump increase radon?
Can radon come from the sump pump or pit? Yes. Radon is a gas that enters your building from the soil beneath and around your house. These gases can enter your home through the footing drain tile that is connected to the sump pump in your basement.
Which states have the most radon?

- Alaska (10.7)
- South Dakota (9.6)
- Pennsylvania (8.6)
- Ohio (7.8)
- Washington (7.5)

- Montana (7.4)
- Idaho (7.3)
Does a dehumidifier get rid of radon?
No, buying a dehumidifier will not make radon go away. Research conducted by the US Environmental Protection Agency (EPA) has clearly disproved this idea.
Does vinyl flooring reduce radon?
As a side benefit, it will also reduce radon levels in your home! DO use moisture-resistant flooring, such as ceramic tile or vinyl composition tile. If you want the look of wood, cover the slab with a vapor-control layer with taped seams and install a glued or dry-fit engineered click-lock floating floor system.
How do you mitigate radon without a sump pump?
Remove soil to create a pit area under the slab opening; the more surface area of soil exposed in the pit, the better. Connect the “pit” to the radon fan with a PVC pipe pathway. This vents the soil gasses and reduces the sub-slab pressure.
Does a sump pump need to be sealed for radon?
If the sump pump cannot be unitized as a suction point, it will need to be sealed so the radon cannot seep into the home through the opening. Even if the sump is used as a suction point, it will still need to be capped.
Which creates the greatest radon threat?
For most people, the greatest exposure to radon occurs in the home where people spend much of their time, though indoor workplaces may also be a source of exposure.
Do air purifiers help with radon?
Do Air Purifiers Help With Radon Gas? Yes, air purifiers help with radon gas reduction to some extent. The air purifiers with activated carbon filter technology are highly effective in trapping radon gas. As mentioned earlier, radon tends to attach itself to numerous airborne and water particles.
What are the first signs of radon poisoning?
A persistent cough could be a sign that you have radon poisoning.
- Persistent cough.
- Hoarseness.
- Wheezing.
- Shortness of breath.
- Coughing up blood.
- Chest pain.
- Frequent infections like bronchitis and pneumonia.
- Loss of appetite.
What time of year are radon levels highest?
Indoor radon levels are normally at the highest in the winter or colder months because of the thermal stack effect, a snowy barrier, and tightly sealed homes. Cold temperatures increase the pressure within the home, meaning more air is being pulled in from the ground, which elevates the risk of radon entering the home.
What types of homes have the most radon?
Exposure to radon can be especially high for people who use their basements as a living space. Like basements, homes with slab-on-grade foundations have many openings that allow radon to enter. Homes with crawl spaces (vented and sealed) can also have elevated radon levels.
