Safe Radon Levels Radon gas is a naturally-occurring byproduct of the radioactive decay of Uranium in the soil. Depending on your geographic location, the radon levels of the air you breathe outside of your home may be as high as 0.75 pCi/L.hile no level of radon gas is completely safe, as with most things in life we must balance the benefits and costs to find our own acceptable levels. We walk outside and work in the sun, exposing ourselves to ultraviolet radiation and increasing our risk of developing skin cancer.

Radon in Real Estate Transactions The only way to tell if a home has elevated levels of radon is to have the home tested. This is easy to do and there are many testing companies and home inspectors who offer radon measurement services.adon is an invisible, radioactive gas created from natural deposits of uranium in the soil. Radon gas can be drawn into a building and accumulate to concentrations that can cause a health concern.

Health effects of radon Health effects of radon. Radon (/ˈreɪdɒn/) is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as the decay product of radium. It is one of the densest substances that remains a gas under normal conditions, and is considered to be a health hazard due to its radioactivity.

Radon and Cancer The results of this analysis demonstrated a slightly increased risk of lung cancer for individuals with elevated exposure to household radon. This increased risk was consistent with the estimated level of risk based on studies of underground miners.owever, people who inhale high levels of radon are at an increased risk of developing lung cancer. Radon can enter homes through cracks in floors, walls, or foundations, and collect indoors. It can also be released from building materials, or from water obtained from wells that contain radon.

- Radon levels in a home, under typical operating conditions, will commonly reach a steady state with mild fluctuations about 12 hours after the house is closed up. Vacant houses will experience factors that may drive radon levels to lower or higher than normal averages, but the effect cannot be predicted.

Colorado Radon Information According to a national residential radon survey completed in 1991, the average indoor radon level in the United States is 1.3 picocuries per liter (pCi/L). The average outdoor level is about 0.4 pCi/L. Excessive radon levels have been found in all of the 50 states.

Radon and Cancer According to the EPA, the average indoor radon level is about 1.3 picocuries per liter (pCi/L). People should take action to lower radon levels in the home if the level is 4.0 pCi/L or higher. The EPA estimates that nearly 1 out of every 15 homes in the United States has elevated radon levels.Outdoors, radon generally disperses and does not reach high levels.adon levels are usually highest in the basement or crawl space. This level is closest to the soil or rock that is the source of the radon. Therefore, people who spend much of their time in basement rooms at home or at work have a greater risk for being exposed.

Radon Mitigation If the results of your first test are higher than 8 pCi/L, then it is recommended that you test again using another short-term test device. The higher the radon concentration above 8 pCi/L, the sooner you should conduct a retest.

How Radon Gas Sneaks into Homes In the U.S., the average radon concentration in surface water is 10 pCi/L but 750 pC/L in well water. However, levels exceeding 20,000 pCi/L are not uncommon. Even some public water supplies have been found to have radon concentrations up to 270,000 pCi/L (NAS 1999b).

Frequently Asked Questions about Radon Though Pennsylvania is an area with a high potential for radon problems, elevated radon levels have been found in every state. In Michigan, nearly one in eight homes would be expected to have a radon problem, and in some counties as many as 40-45% of the homes could have problems.

Radon - Rn Exposure to high levels of radon through breathing air is known to cause lung diseases. When long-term exposure occurs radon increases the chances of developing lung cancer. Radon can only cause cancer after several years of exposure. Radon may be radioactive, but it gives of little actual gamma radiation. As a result, harmful effects from exposure to radon radiation without actual contact with radon compounds are not likely to occur. It is not known whether radon can cause health effects in other organs besides the lungs. The effects of radon, which is found in food or drinking water, are unknown.

There is no Safe Radon Level! This 5-year study proves that radon even at the low levels found in homes causes lung cancer and that the risk is proportional to the radon level. The study shows that the exposure of adult women to radon over 15 years at the EPA action level of 4 pCi/L increases the lung cancer risk by 50 percent.

There is no Safe Radon Level! The risk to the average person of dying of radon-caused lung cancer due to a lifetime exposure to 4 pCi/L radon level at home is 2.3 percent. If there are five people in your family, the chances that someone becomes a victim of radon over 10 percent.early 8 million US homes, or 1 out of every 15, have radon levels above the EPA's 4 pCi/L action limit and nearly 1 out of 6 exceed the EPA's 2 pCi/L consider action limit.

- Radon is a naturally occurring radioactive gas that is produced by the radioactive decay of radium. Breathing high concentrations of radon can cause lung cancer.ery high levels of radon (above 10 or 15 pCi/L) are definitely dangerous. There are homes with these concentrations! Lower levels (2 to 10 pCi/L) are probably somewhat dangerous, with higher levels leading to higher risks.

HUD Regulation for Radon Testing and Mitigation Mitigation Requirements. If testing shows radon levels above the 4.0 picocuries per liter (4.0 pCi/L), then the applicant must either mitigate in 100% of ground level units/rooms or test 100% ground level units/rooms. RDS Environmental understands all of the intricacies of these new requirements.

The Radon Fraud Radon is a naturally occurring radioactive gas that is emitted from soils and rocks and is in some water sources. The EPA promotes radon monitoring and sealing of homes to prevent an indoor radon gas hazard. The range of radon gas in US homes varies by a factor of over 1000.ddly, while some studies report a link between radon and lung cancer, there was no association for lung cancer among houses located near uranium or radium processing waste sites. At best, the association between radon gas and lung cancer is considered weak. [13]. How radon gas gets in your home.

Radon and Cancer Radon is a radioactive gas released from the normal decay of the elements uranium, thorium, and radium in rocks and soil. It is an invisible, odorless, tasteless gas that seeps up through the ground and diffuses into the air.he U.S. Environmental Protection Agency (EPA) recommends taking action to reduce radon in homes that have a radon level at or above 4 picocuries per liter (pCi/L) of air. About 1 in 15 U.S. homes is estimated to have radon levels at or above this EPA action level.
