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.

Buying a home is arguably the most important, exciting and nerve-wracking purchase a person will ever make. This is the reason you need a great home inspector, and Dave Valley is just that. He is empathetic – he understands and appreciates the various emotions a potential home-buyer goes through. Most importantly, Dave provides you with objective information so you can make the most informed decision possible.
It was a pleasure working with Dave – he contains all the qualities that make a great home inspector – he is the consummate professional, prompt, courteous, meticulous in his detail and honest. Dave was reasonably priced – in fact Dave charged me the same amount I spent 10 years earlier on a smaller house and provided a far better work product.
Prompt
I arrived at the house at the agreed upon time on a cold and nasty day, and found Dave outside inspecting the exterior of the home. He was already a half hour into his inspection – I think this exemplifies and is symbolic of the fact that Dave is respectful of his client’s time.
Courteous
Dave was pleasant to deal with, personable and thoughtful not only to his client but also to the buyer’s real estate agent.
Detail-oriented
Dave spent almost four hours in his investigation of a 2,000 square foot house. He answered all my questions and reviewed every observation he had with me. David provided a detailed report, and encouraged me to call and email him to discuss the report and to ask questions.
Conclusion
The highest compliment I can give Dave is to say that I would use him again and will encourage and recommend him to others.
