Things Every Home Owner Should Know About Testing


Radon testing in Minneapolis is one of the only ways to know whether your home has high levels of radon or not. However, what exactly is radon and why is it dangerous to health?

Radon is a colorless and odorless radioactive gas that is produced by decaying uranium. Radon is found in all soils and is also available in the air that you breathe but in very low proportion.

Radon is such a gas that enters the home and gets trapped inside. As already discussed above that radon is a radioactive gas, this means that long exposure to radon can cause lung cancer. According to a survey, radon exposure kills more than 21,000 people every year.

How Does Radon Traps Into Your House?

The radon gas transfers from the soil into your home directly through the pores in concrete. Although, it can also enter through the gaps in walls and floors. It doesn’t matter how old your house is, radon will be available in your home. However, the level of the radon depends on the way your house interacts with the surrounding soil.

While the only way to find out how much radon is there in your home is through radon testing.

Short Term Test

Short term test is done to check if further testing is warranted. Short term test uses devices that are activated charcoal-based or electret ion bases that measure radon levels for 2-7 days. After that, you need to send the device to the lab for the results. You can buy these radon test devices from the home centers, hardware stores or from home retailers.

Long Term Radon Test

As the name suggests, these tests measure levels of radon for 90 days to 1 year. Tests like the AccuStar test which is based on alpha particle tacking. This test is a more accurate indicator of average annual levels as it varies significantly from day to day and month to month based on factors like a drop in air pressure, gusty winds, and variable soil moisture. You can buy long term radon test from state radon agencies or online retailers.

Continuous Radon Test

There are many devices like Safety Siren Pro Series that continuously test radon levels in your home. All you need to do is to plug that digital meter into your standard outlet. These devices can be used both short-term and long-term testing to give you a running average every day.

What Should be Done In Case of High Levels of Radon?

If the radon test devices register 4 picoCuries per liter (pCi/L) or higher then EPA recommends doing a second radon test. A long-term test will give you the most accurate result but if you want results quickly then you can opt for a short-term test as well.

How Can You Lower the Level of Radon?

You can reduce the levels of radon by trying these easy repairs. With these efforts, you can reduce the levels of radon significantly, but if your level is slightly elevated then these repairs might make a difference.

  • Seal all the foundation cracks, construction joints, and other openings with polyurethane caulk.
  • If you have a sump pump then you can install an airtight cover on it.
  • You can also cover the soil in crawl spaces with polyurethane plastic sheet which has a minimum thickness of 6 mm.
  • You can also try and seal the concrete.

After you have done all these things, you can retest the levels of radon. If the levels of radon are too high then you can consider installing a radon mitigation system or do a home inspection in Minneapolis.
