A Good Radon Mitigation System Can Greatly Reduce or Eliminate the Danger of Radon in a Home.owever, a poor mitigation system that does not lower the radon level sufficiently is almost more dangerous than none at all; because it can give a false sense of safety. Many people wrongly assume since there is a radon mitigation system the radon problem has been eliminated, and far too often it has not.
