Where Does Radon Come From?

Radon is the gaseous form of the radioactive element radium. Radium itself is the product of uranium decay. Uranium is naturally present in soil, rock, and groundwater. Continually over time, uranium breaks down into radium, which continues to decay until it transforms into radon gas.

In this gaseous form, radon wafts up through the soil and into the air. Ordinarily, radon harmlessly disperses into the atmosphere. Unfortunately, if radon gas is released beneath a building, it often seeps inside the building and becomes trapped. This is why many homes in the Twin Cities have a radon problem.

Within your home, radon may build up to dangerous levels, with harmful consequences for anyone who breathes it in. The most harmful radon levels typically occur at the lowest level of your home, whether that’s the basement, crawl space or first floor.

How is Radon in My Home?

Radon gas commonly infiltrates homes in the Twin Cities through these avenues:

  • Cracks in the floor or walls of your basement.
  • Gaps around pipes and utility lines entering your home.
  • Spaces around floor drains and sump pumps.
  • Construction joints in concrete structures.
  • Crawl spaces that have exposed earth.

All of these openings allow radon to filter into your home, where the gas will have a more difficult time escaping into the open air. As radon accumulates to unsafe levels in basements and lower floors, those living in the home will unknowingly breathe in the gas, damaging their lungs over time.

If you suspect a radon problem in your home, your best option is to confirm the presence of radon and then reach out to a licensed radon mitigation company in the Twin Cities area for help.
