Please note:
Radon is everywhere! Every house is different!
The only way to know if the radon level is safe in your home is to have it tested!

Radon Measurement

Radon Mitigation.
Radon becomes destructive when it undergoes radioactive decay. When radon decays, radiation and radon progeny (daughters) are produced.
These radon progeny are composed of heavy metal particles of lead, polonium, and bismuth that are electrically charged. They are so minute that they become airborne, traveling through the air where they are inhaled.
How Radon Enters the Lungs
Other more active radon particles travel deeper into the body's tissues; therefore, they are less concentrated and less harmful. Whilst other radon particles are so energetic that they pass completely through the body. These radon particles are the least damaging since they do not become lodged within the body.
How Radon Damages the Lungs
Large concentrations of radon are not necessary to cause lung cancer. A single radon atom alone can cause lung cancer. Radon particles damage cells by altering their genetic material. The damage typically kills or disables cellular reproduction. However, in some cases, the damaged cell may survive and continue to reproduce in a mutated state, forming cancerous tumors.

ACTION LEVELS: 4.0, 2.7, 2.0 pCi.L
4.0 pCi/L Achieving below the USEPA action level of 4.0 pCi/L can be accomplished for virtually any home. Older homes can present challenges due to construction practices when they were built and in special cases it can become a question of expense versus benefit.
2.7 pCi/L The World Health Organization (WHO) has recently modified their recommended action level from about 5.3 pCi/L to about 2.7 pCi/L. This reflects recommendations regarding life-long, direct exposure. The change reflects recent population studies for statistical evidence of radon induced lung cancer.
2.0 pCi/L The USEPA recommends to consider action between 2 and 4 pCi/L since no exposure is safe. However, around about 2.0 pCi/L and lower, the lower limits of sensitivity for test devices has been reached and errors up to 300% have been seen to occur. Hence, verifying less than 2.0 pCi/L is not truly feasible (though some contractors knowingly or unknowingly make such claims or warranties).
0.7 pCi/L Outside air anywhere on earth. This is so low that even the best equipment scientists use can only estimate between 0.4 to 0.8 pCi/L.
