Radon causes Cancer Radon gas is the number two cause of lung cancer in the US after cigarette smoking. It is difficult, in many instances, to pinpoint the blame and yet radon & radon gas are still responsible for over 20,000 deaths per year in the United States. In addition, there are many other complications to our health & respiratory system that can be attributed to the long term exposure of radon gas.

Radon is a part of our natural world and exists worldwide. However, without proper precautions it has the capability to destroy lives. We have an easy and affordable way to test for dangerous levels of radon gas for either air or water. Radon Gas Test Kit Prices

Radon gas is odorless & invisible. We cannot see, smell or taste it, but it exists in the air you breathe and gets into the water you drink. Typically the greatest exposure to radon is in the home, especially in the lowest levels of the home that make contact with the ground where the concentrations of radon gas are usually higher. Don't worry though; it does not mean you have to move out and doze it to the ground! The good news is that radon gas can be eliminated easily once detected. I recommend getting several estimates from EPA approved contractors in your area. Check their references & credentials before the time of your appointment. A qualified contractor will give you proper recommendations & help you to select the mitigation process that suits your home the best. Each circumstance is different.

The Basics on radon gas: Radon is a radioactive gas found in many soils, rock, and water throughout the world. It is naturally occurring in many types of terrain and geography. Radon has a half-life of 3.823 days. Radon has numerous different isotopes, but radon -220, and -222 are the most common. Radon is a very heavy gas and emits alpha particles. Radon causes lung cancer and is a threat to our respiratory health. Radon chemical symbol Rn and Atomic Number 86.

Where does radon come from? Radon is the decaying byproduct of Uranium. Since uranium is essentially ubiquitous in the earth's crust, radium-226 and radon-222 are present in almost all rock, soil, and water.

EPA Recommends:

  • Buying or selling a home; have it tested for radon.
  • Mitigate if the radon level is 4 PicoCuries per liter (pCi/L) or higher.
  • New home? ask if radon-resistant construction features were used.
  • Well or Spring water? Have it tested for radon gas in water.
  • A long term radon gas test will provide the best accuracy.
Radon levels less than 4pCi/L still pose a risk with long term exposure.
