Radon Gas Risk Factor Safety Levels Comparison

How do you put the risk from radon into perspective, especially since all homes contain some level of radon gas in them and there is no “safe level” except zero?

I have found the following charts to be helpful in evaluating risk: (please click on the pictures for a full sized detailed view)

Notice that the risk for a radon level at the EPA action limit of 4 picoCuries/liter is similar to the same risk of dying in a car wreck. I have personally observed several residences that I have tested in Dallas county to EXCEED this limit including my own home.

Radon is linked to not just lung cancer, but recent epidemiological evidence also suggests that radon gas may also be a risk factor and contributor to

  1. Acute Myeloid Leukemia (AML)   13 % – 25 % of all cases worldwide.
  2. Kidney cancer
  3. Certain childhood cancers
  4. Melanoma

I have personally verified a number of homes that exceeded the EPA action limit including one that had radon levels even higher than mentioned in the article.
