Do You Know Your Number?

  • Radon is measured in picocuries per liter (pCi/L). The action level recommended is 4pCi/L.
  • Radon is the second leading cause of lung cancer in the U.S. (The leading cause is smoking.)
  • It is naturally occurring and is found in almost any kind of soil or rock in at least trace amounts.
  • It is tasteless, odorless, colorless, and radioactive.
  • It enters buildings through openings in the foundation floor or walls (sump openings, crawlspace, floor/wall joints, cracks, etc.)
  • It has no warning symptoms. (It does not cause headaches, nausea, fatigue, etc.; the only known health effect is an increased risk of lung cancer.)
  • Nearly one in eight Michigan homes would be expected to have elevated radon levels. In Jackson County, one in six could have an elevated level.
  • In some counties, as many as 45% of the homes could have a problem!
  • Testing is easy and inexpensive.
