How do you read a radon inspection report?
Interpreting Your Radon Test Results
- Greater than or Equal to 4.0 pCi/L. Above 4.0 pCi/L, you are putting yourself at unusually high risk for lung damage and cancer.
- Between 2.7 and 4.0 pCi/L.
- Less than 2.7 pCi/L.
What do my radon test results mean?
What do my test results mean? Below 2 pCi/L (74 Bq/m3) is considered a low level of radon and a good test result. Above 4 pCi/L (148 Bq/m3) is considered a dangerous level of radon and the EPA recommends taking action to reduce radon levels.
What should a radon reduction system read?
The readout on the manometer should be between 0.5in – 1.75in. In most cases these are acceptable levels indicating, your system is operating correct. When your Radon system is shut off the fluid should rest at zero if it does not then your manometer is low on fluid.
How bad is a radon level of 8?
Radon Risk If You Smoke
| Radon Level | If 1,000 people who smoked were exposed to this level over a lifetime*… |
|---|---|
| 10 pCi/L | About 150 people could get lung cancer |
| 8 pCi/L | About 120 people could get lung cancer |
| 4 pCi/L | About 62 people could get lung cancer |
| 2 pCi/L | About 32 people could get lung cancer |
What are acceptable radon test levels?
According to Health Canada, the acceptable level of radon in the average home is 200 becquerels per cubic metre (200 Bq/m³), while the World Health Organization sets the acceptable level at 100 becquerels per cubic metre (100 Bq/m³).
What are acceptable radon levels?
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 are acceptable levels of radon?
What number should radon read?
Your radon mitigation’s manometer readout should be between 0.5in-1.75in on the Manometer (U shaped- looks like a thermometer). This is NOT the level of Radon in your home. It is simply the amount of vacuum your mitigation system is generating.
What time of year is radon highest?
winter
The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.
What is a high radon reading?
Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L.
How do you measure radon levels?
You can hire a professional tester or do it yourself with a kit you buy at a hardware store or online. Follow the instructions for leaving the kit in your house for the required number of days. Then mail it to a lab and wait for the results. If radon levels in your home are high, you can take steps to lower them.
What is a high reading for radon?
4 pCi/L
Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L.
What should I do during radon testing?
This test can be used during any season as long as closed building conditions can be maintained.
How often should your home be tested for radon?
Another common question is how often a home should be tested for radon. The EPA recommends testing for radon every 2 to 3 years and says to keep all of the test results. It is also a good idea to test for radon before and after any major renovations to a home.
What is radon and why do we test for it?
A professional radon testing can tell you if the radon levels in your home are dangerous. Radon gas forms as the result of uranium decaying in soil. The radioactive gas is released from the soil and travels upward into the air.
How accurate are radon tests?
Here are three simple rules for getting an accurate radon reading in your home. Test Regularly – The EPA recommends that you test for radon in your home every two years. Test Long-Term – Every time you test for radon, opt to use a long-term test rather than a short-term one.
