Radon - What Is It?

what is radon

Radon is a radioactive gas. It's completely colorless, odorless, tasteless, and chemically inert. Unless you literally test for it, there is no way of actually telling how much Radon gas is presently in your home.

Radon gas is formed by the natural radioactive decay of radium and uranium in rock, soil, and water. Naturally existing, low levels of uranium occur widely in the Earth's crust. It can be found in all 50 states, with radon levels fluctuating throughout the U.S. Once produced, radon moves through the ground to the air above. Some radon gas remains below the surface and dissolves in water that collects and flows under the ground's surface.

Radon has a half-life of about four days - half of a given quantity of it breaks down every four days. When radon undergoes radioactive decay, it emits ionizing radiation in the form of alpha particles. It also produces short-lived decay products, often called progeny or daughters, some of which are also radioactive. Unlike radon, the progeny are not gases and can easily attach to dust and other particles. Those particles can be transported by air and can also be breathed. The decay of progeny continues until stable, non-radioactive progeny are formed. At each step in the decay process, radiation is released.

Here is what my clients have to say about my home inspection services:

Hi Dave,

I wanted to thank you for spending the time with us today. I couldn't have been more pleased with your inspection. I was a bit nervous picking someone to inspect the house as it almost seemed like drawing straws (since I had no references to go on), with the possibility that I could draw the short straw, however, I can honestly say that I definitely didn't draw the short straw this round. The level of detail that you put into the inspection really helped lift a huge weight off my shoulders and I am more than confident in your assessment of the house. I also appreciate all the advise and tips you shared with us during the walk though.

Thanks again for all your help!

Cheers,

Ryan
