What are acceptable radon levels in Canada?
Although there is currently no regulation that governs an acceptable level of radon in Canadian homes, Health Canada, in partnership with the provinces and territories, has developed a guideline. The current Canadian guideline for radon in indoor air for dwellings is 200 becquerels per cubic metre (200 Bq/m3).
What is a safe level of radon?
EPA recommends homes be fixed if the radon level is 4 pCi/L (picocurries per liter) or more. Because there is no known safe level of exposure to radon, EPA also recommends that Americans consider fixing their home for radon levels between 2 pCi/L and 4 pCi/L.
What areas of Canada have high radon levels?
The data obtained by CBC News shows that the five highest results in the country were found in:
- Armstrong Station, Ont. (5,657 Bq/m3)
- Bas-Paquetville, N.B. (5,590 Bq/m3)
- Sparwood, B.C. (2941 Bq/m3)
- Gaspé, Que. (2,923 Bq/m3)
- Gooderham, Ont. (2,741 Bq/m3).
What province has the highest radon levels?
This survey confirmed that radon levels vary significantly across the country and that there are areas where high levels of indoor radon are more prevalent. Manitoba, New Brunswick, Saskatchewan, and the Yukon had the highest percentages of participant homes which tested above the radon guideline.
How much does radon mitigation cost in Canada?
between $2,500-4,000
The cost for the installation of a radon mitigation system typically ranges between $2,500-4,000.
Is 3.4 radon safe?
FAQs: Acceptable Radon Levels. What constitutes an acceptable or safe radon level? According to the EPA, the maximum “acceptable” level of radon is 4.0 pCi/L, but even that level is not “safe”, per se. The EPA strongly recommends you consider radon mitigation between levels 2.0 and 4.0.
How do you eliminate radon?
An active radon sump, fitted with a fan, is the most effective way to reduce indoor radon levels. Sumps work best under solid floors and under suspended floors if the ground is covered with concrete or a membrane. Occasionally, passive sumps without a fan may reduce radon levels.
Is radon a problem in Ontario?
Radon gas can accumulate to high concentrations in basements and lower floors of homes and buildings. About 25 percent of Ontario homes surveyed from 2009 to 2013 had radon concentrations that require remedial action according to the World Health Organization.
Can air purifiers help with radon?
Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.
Is radon really that bad?
Radon is part of the environment and generally isn’t harmful. But long-term exposure to high levels of radon can put you at risk of developing lung cancer, especially if you smoke.
What states have radon gas?
High radon areas in the U.S. tend to be in the northern section of the country due to the types of soils found there. States with high concentrations of radon include Iowa, North Dakota, South Dakota, Maine, Minnesota, Illinois, Kansas, Montana, Idaho, Wyoming, Colorado, Pennsylvania, and Virginia. Most or all of these states fall in zone one
What factors can change radon test levels up or down?
The level of radon can commonly be elevated in the warmer months. The reason that radon levels can go up and down in the summer is because of a temperature change, though this one is less extreme. During the day, the sun beats down and heats up the house from the outside in, but at night, there is a rapid cooldown.
Are radon measurements accurate and reliable?
While any measurement system has an associated variability in precision and accuracy, we expect that radon test devices that are used properly will provide accurate and reliable results. The study presented here only represents a part of the picture of accuracy and reliability.
