Oklahoma specific radon and radon level information can be found throughout this site. You will be able to find information about certified radon inspectors in Oklahoma, as well as detailed radon level information for every county in Oklahoma.
Radon is constantly being generated by the radium in rocks, soil, water and materials derived from rocks and soils, such as certain building materials. Radium is a decay product of uranium which is naturally occurring in the soils and rocks of the earth's crust. Uranium is present at about 0.5 to 5 parts per million (PPM) in common rocks and soils. The concentration of radon gas in the soil will be related to the amount of uranium present. However, this is not a good indicator of the level of radon in an individual home. The radon concentration in a home is dependant on the type of soil the home is built on. Cracks, openings and various penetrations in the building foundation will provide the pathway for the radon in the soil to enter the home. The ventilation rate and air flow patterns within a house are important factors that will affect how much radon will be pulled into different areas within the house.
Radon can also be dissolved in ground water and can be introduced into the indoor air through the aeration of well water during its use in washing machines, showers, etc. However in New York State, with a few exceptions, this component is usually relatively small compared to the amount of radon entering the home from the soil.
There is no doubt that Radon gas is a known human lung carcinogen. Prolonged exposure to high levels of Radon gas can cause lung cancer. Millions of homes and buildings contain high levels of radon gas. EPA's efforts are directed at locating the homes with high levels and encouraging remediation of them.
As a means of prevention, EPA and the Office of the Surgeon General recommend that all homes below the third floor be tested for Radon. Because Radon is invisible and odorless, a simple test is the only way to determine if a home has high Radon levels. EPA recommends mitigating homes with Radon levels 4.0 picocuries per liter or greater. There are straightforward reduction techniques that will work in virtually any home.
Radon gas in the indoor air of America's homes poses a serious health risk. More than 20,000 Americans die of radon-related lung cancer every year. Millions of homes have an elevated radon level. If you also smoke, your risk of lung cancer is much higher. Test your home for radon every two years, and retest any time you move, make structural changes to your home, or occupy a previously unused level of a house. If you have a radon level of 4 pCi/L or more, take steps to remedy the problem as soon as possible.
"Americans need to know about the risks of indoor radon and have the information and tools they need to take action. That's why EPA is actively promoting the Surgeon General's advice urging all Americans to get their homes tested for radon. If families do find elevated levels in their homes, they can take inexpensive steps that will reduce exposure to this risk," said Jeffrey R. Holmstead, Assistant Administrator, Office of Air and Radiation, U.S. Environmental Protection Agency (EPA).
"Based on national averages, we can expect that many of the homes owned or financed by federal government programs would have potentially elevated radon levels. The federal government has an opportunity to lead by example on this public health risk. We can accomplish this by using the outreach and awareness avenues we have, such as EPA's Web site, to share information and encourage action on radon to reduce risks," said Edwin Piņero, Federal Environmental Executive, Office of the Federal Environmental Executive (OFEE).
