What is radon?

  • Radon is a colorless, odorless radioactive gas that seeps up from the earth. When inhaled, it gives off radioactive particles that can damage the cells that line the lungs.

  • Long term exposure to radon can lead to lung cancer. In fact, over 21,000 lung cancer deaths in the U.S. each year are from radon, making it a serious health concern for all Minnesotans.

Where is your greatest exposure to radon?

  • While radon is present everywhere, and there is no known, safe level, your greatest exposure is where it can concentrate-indoors. And where you spend most time-at home. Your home can have radon whether it be old or new, well-sealed or drafty, and with or without a basement.

How does radon enter a home?

  • Since radon is produced from soil, it is present nearly everywhere. Because soil is porous radon gas is able to move up through the dirt and rocks and into the air we breathe. If allowed to accumulate, radon becomes a health concern.

  • Two components that affect how much radon will accumulate in a home are pathways and air pressure. These components will differ from home to home.

  • Pathways are routes the gas uses to enter your home and found anywhere there is an opening between the home and soil.

  • Air pressure between your home’s interior and the exterior soil is what helps to draw a radon gas into the home via pathways.

Where does radon come from?

  • The soil. Radon is produced from the natural decay of uranium that is found in nearly all soils. Uranium breaks down to radium. As radium disintegrates it turns into radioactive gas…radon. As a gas, radon moves up through the soil and into the air you breathe.

How serious is radon a problem in Minnesota?

  • High radon exist in every state in the US. In Minnesota, one in three homes has radon levels that pose a significant health risk, and nearly 80% of counties are rated high radon zones. Some factors that further contribute to Minnesota’s high radon levels include:

  • Minnesota’s geology produces an ongoing supply of radon.

  • Minnesota’s climate affects how our homes are built and operate.
