Radon may be a present radioactive gas that’s released through the decay of elements like uranium, thorium, and radium found in soil and rocks. there’s no escaping radon gas entirely, and no radon gas level is deemed safe. Fortunately, the gas disperses within the air in order that most outdoors levels are low. The matter occurs when there’s a build from radon gas within the home that can’t readily escape. Remedial actions should be initiated where airborne radon levels exceed 4 pCi/L and water radon levels are above the 20,000 to 25,000 pCi/L range.
Radon gas can’t be detected through the senses. it’s tasteless, colorless, and odorless. People that inhale substantial amounts of radon gas are at an increased risk of developing carcinoma. Radon gas can enter homes through any cracks in foundation walls, unfinished crawl spaces, gaps around pipes that enter the house, sump pumps, and floor drains. Even new construction isn’t always without gaps, cracks, crevasses, and crawl spaces. Radon gas permeates upwards from the bottom much the way moisture or water vapour moves and may seep through any openings.
Radon may be a radioactive gas produced naturally when uranium breaks down within the bedrock, soil, and groundwater. Although it’s not lethal because it permeates the air, prolonged exposure to radon gas is often harmful. those that are exposed for a lengthy period of your time have a 2%-5% lifetime risk of getting carcinoma. For those that smoke regularly, this risk increases to almost 20%.

Radon gas protection system Key Facts:
- Radon may be a radioactive gas that you simply cannot see, smell, or taste
- Radon is the second leading explanation for carcinoma
- 7% of homes in Canada have high levels of radon
What are the dangers of high indoor radon levels?
Left unmitigated, high levels of radon during home can create a long-term health risk for residents.
When inhaled, radon gas particles remain in lung tissue and start to decay. As the radon particles decay, they release bursts of radiation which will damage the lung tissue cells. Over time, cell damage can cause the event of lung cancer. Radon is that the second leading explanation for carcinoma and it’s estimated that 16 percent of carcinoma deaths among Canadians are due to indoor radon exposure.
The risk of developing carcinoma from radon depends on:
- the concentration of radon within the air that’s breathed
- the duration of exposure to radon
- whether the person may be a smoker
How Does Radon Get into a Home or Building?
The atmospheric pressure inside a basement is usually above pressure within the soil surrounding the inspiration of a home. The difference in pressure acts sort of a vacuum which pulls air into the house through cracks, holes, or openings in slabs and foundation walls, crawl spaces, floor joists, rim joists, pipes, and electrical conduits, floor drains, and sump pumps. Floor drains and suction pump openings are often a serious source of radon infiltration into the house. Radon mitigation utilizes a vent pipe and fan systems to vent harmful radon gas out of the house. Spray foam, also as polyurea, works to seal even the littlest cracks and crevasses to make sure that radon gas cannot seep into the house.
Testing is that the only means of discovering whether or not radon gas may be a problem within the home. Radon gas can accumulate when homes aren’t properly ventilated. Atmospheric conditions can affect what proportion of radon gas is released into the air from day to day or month to month. Therefore, it’s best to check for radon gas over a period of your time to get an accurate reading. make certain to rent knowledge for any testing.
Radon Gas Mitigation Factors
It is advised to rent a licensed professional to properly test for radon gas levels. Radon gas data on maps should be viewed as a generalization over an outsized area. Radon levels can vary within the areas shown. The subsequent are considerations for deciding if radon gas mitigation is required and therefore the sort of mitigation which will be best.
- The level of radon gas from testing
- The source(s) of the radon gas
- The structural integrity of the house or building
- Unfinished crawl spaces
- Ventilation routes
Spray Foam or Polyurea, First Line of Defense Against Radon Gas
Spray foam is an insulation and a coating while polyurea is one among the foremost highly durable coatings available. Both sorts of applications work because they will seal large and little cracks, gaps, and holes, providing an endless, monolithic barrier that seals and protects as a primary line of defense against radon gas. Both SPF and polyuria are excellent materials that also serve to enhance the structural integrity of the surfaces during which they’re applied.
Where to use it and how?
For basements, use spray foam beneath the slab to keep the floor from cooling and to keep warm air inside and radon outside.
For crawl spaces use spray foam to exposed soil and rocks in crawl spaces adding warmth protection against radon
Seal the foundation wall and floor joints to create a continuous airtight seal that will low hating bills and keep the radon outside.
Seal the space around pipes and electrical wires that enter the building for continuous protection and complete the barrier.
Questions & Answers
Q: Can radon problems always be fixed?
A: Excessive radon levels are often successfully mitigated in every sort of home. it’s best to consult a radon professional trained to know how radon enters buildings and the way resulting radiation levels are often effectively managed to make sure the security of all occupants. the kinds of mitigation systems vary counting on the radon source and sort of home.
Q: Is extensive mitigation required?
A: It is vital to notice that a lot of people feel that elevated radon concentrations within a home can simply be fixed by sealing cracks and openings within the lowest level of the house. Using this approach as a stand-alone method to lower radon concentrations isn’t recommended and infrequently effective. To make sure high radon levels are successfully addressed, homeowners should test, or have a contractor test the house after any radon mitigation system is first activated to form sure it’s working effectively.
Spray Foam Insulation – Radon Remediation And Prevention
When applying spray foam, you’re adding quite just insulation.
Spray Foam Insulation is the most effective manner employed by experts for shielding the building from radon harmful effects. It’s already standard knowledge that the spray foam is the superior choice for insulation providing high radon-protection to the building where applied.
Spray foam creates an endless air barrier that acts because of the first line of defense against not only radon but also other malignant gases. Besides this, spray foam may be a vapour barrier that protects the inspiration. It protects a building from major damages that will occur with time.
