Radon is a colorless, odorless, tasteless and invisible gas produced by the decay of naturally occurring uranium in soil and water. Radon Gas Is All Around Us. For more information about radon in drinking water please call the state radon office or the Safe Drinking Water Hotline at (800) 426-4791. Remove radon from the water using granular activated carbon. Unfortunately, that's not possible. Radon can also enter the home through well water but usually carries little risk in Kentucky. High levels of radon can cause lung cancer, particularly for smokers and ex-smokers. The long-wave radiation is infrared and it warms the skin. 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. Cosmic radiation consists of a variety of very energetic particles, including protons, muons, and neutrinos, which bombard the earth from outer space. It encourages the EPA to consider lowering its current "action level" (the level at which remedial action is recommended) of 4 pCi/L for radon exposure, given that new radon risk data have emerged since the existing action level was set. Considering the high cost of mitigation methods available to homeowners in 1980s (averaging $1,200 but up to $2,500), EPA issued its recommendations: EPA did not want to force homeowners to install costly radon mitigation systems, leaving the decision up to each homeowner. Read More Sunshine is a radiation. Copyright © 1998-2021 Novion Radon Mitigation & Concrete Waterproofing, a higher radiation dose from radon at home than from all other natural or man-made sources combined, 0.4 pCi/L as the target radon level for homes, the 4 pCi/L action limit is not a "safe" level, cancer risk from radon at the "action" limit is about 1,000-times higher, Most radon-attributed deaths (70%) are caused by radon levels lower than 4 pCi/L, the EPA "action" level of 4 pCi/L increases the lung cancer risk by 50 percent, Lung Cancer Prevention Starts with Radon Mitigation. 1 cancer killer. The societal cost of mitigating all homes to a 4 pCi/L level was estimated at $44 billion but that would rise to $101 billion if the action level was set at 2 pCi/L. Ionizing radiation damages DNA and just one mutant cell can cause cancer. Beyond the ultraviolet radiation is a higher-frequency radiation emitted from nuclei of unstable radioactive atoms - ionizing radiation. An official website of the United States government. Radon is a naturally occurring radioactive gas that can cause lung cancer.You can’t see or smell radon. Radon is the "silent killer." And, the societal cost of lung cancer deaths caused by radon is relatively low because it kills so quickly, often within months. Assuming the highest radon level in modern mines, the average person receives in his home at 4 pCi/L over 12 years the same radiation dose as if he/she worked for 5 years in a uranium mine. People spend most of their time at home - on average 70%, but more in case of women and particularly, children. Natural radioactivity is common in the rocks and soil that make up our planet – over 60 radionuclides (radioactive elements) can be found in nature. The average (mean) radon level in US homes is 1.25 pCi/L, or three times higher than the average level outdoors. The preferred radon level measurement unit is Becquerels per cubic meter, Bq/m3. Most radon-attributed deaths (70%) are caused by radon levels lower than 4 pCi/L (BEIR VI, 1998). 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. The President's Cancer Panel issued its "Reducing Environmental Cancer Risk: What We Can Do Now" in 2010. Save a life. 489 Bridgeport Ave Suite 101336 Shelton,CT 06484 1-800-472-0603, RadonSeal®, LastiSeal®, and CrackWeld® are registered trademarks. Operated under a … Here are a few pages to read that may help – How to remove radon gas from basements and crawl spaces. Radiation from these particles damages our lung tissue, and over a long period may cause lung cancer. United States Environmental Protection Agency, Radon Zone and Radon Information Near You, National Radon Action Plan: A Strategy for Saving Lives, Find Local Radon Zones and State Contact Information, Find a Radon Test Kit or Measurement and Mitigation Professional, Radon Media Resources for Partners and Stakeholders, Consumer's Guide to Radon Reduction: How to Fix your Home, Radon-Resistant Construction Basics and Techniques, Proposed Criteria for Radon Credentialing Organizations. (Radon causes 26% of lung cancer deaths among non-smokers.). A Curie is a unit of radioactivity equivalent to 1 gram of radium and the prefix "pico" means a trillionth. It is merely the result of a macroeconomic cost/benefit analysis for the US population at large. 1-800-644-6999*– Radon Fix-It Hotline for general information on fixing or reducing the radon level in your home. But radon decay products, radioactive solid particles, much smaller than household dust, float in the air and get trapped in our lungs, trachea, and bronchi. But homes draw concentrated radon gas from the ground. However, two thirds of the total effective radiation dose to the average American from all natural sources comes from radon and its progeny. Test your home today. This process may lead to development of a national primary drinking water regulation (NPDWR) in the future. Yet, the average person receives a higher radiation dose from radon at home than from all other natural or man-made sources combined. 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. Test. The Safe Drinking Water Act (SDWA) includes a process that EPA must follow to identify and list unregulated contaminants. If the cost of radon mitigation was only $600, the action limit recommended to homeowners would have been set at 2 pCi/L. As the US EPA explains, there is no safe level of radon, a radioactive gas which causes lung cancer, the No. Background radiation levels are a combination of terrestrial (radium, thorium, radon, etc.) The visible light is in the middle of its range of wavelengths. Nearly 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. deaths caused radon in the US each year. Promoting Radon Awareness. Exposure to radon is the second leading cause of lung cancer after smoking. Radon in homes is more concentrated and far more dangerous than outdoors - the National Academy of Sciences estimates that the outdoor radon causes only 800 out of the total of 21,000 lung cancer Be informed of the dangers of radon & rely on a radon professional. The best thing to do is run your water through a granular activated carbon unit to remove the radon. The Environment Protection Agency was given the task of developing practical guidelines. For more info visit short-term vs. long-term radon test kits. How radon sneaks into homes Nearly 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 … "Action limit" does not imply safety. Because radon is nine times heavier than air, elevated radon levels build up in basements and on lower floors. They are not a sound basis for radon mitigation decision. Radon can have a big impact on indoor air quality. The average (mean) radon level in US homes is 1.25 pCi/L, or three times higher than the average level outdoors. Fix. EPA Action Level Buying or Selling YOUR HOME? Outdoor radon levels in the U.S. range from 0.02 to 0.75 pCi/L (picoCuries per liter), averaging 0.4 pCi/L. Then, almost all is harmlessly exhaled by our lungs or skin until equilibrium is established between the ambient and internal radon concentrations. Purchase a Radon Test Kit Find a Radon Professional Nearby Find a RadonAway Authorized Radon Pro Now! Radon mitigation equipment such as passive radon stacks are becoming mandatory in many regional building codes, and the can be installed afterwards in some situations, but it really depends on your specific level of finishing. The Kentucky Radon Program encourages continuous education on radon gas. Unlike radon levels in homes, occupational radon limits are governed by law and regulations. Contact Us to ask a question, provide feedback, or report a problem. One Becquerel means one radioactive disintegration per second, and 4 pCi/L equals to 148 Bq/m3. There are several types of ionizing radiation: Radon decay chain offers a full menu of ionizing radiation: alpha and beta particles, and gamma rays. Its 5-year survival rate is only 10–14 percent and thus, it costs only several billion dollars per year. Safe radon levels. Find Radon Zone and Radon Information Near You. The Occupational Safety and Health Act (OSHA) limits cumulative radon exposure in the workplace to 30 pCi/L based on 40 working hours per week. You should always try to reduce radon to a practical minimum - if you just settle for 4 pCi/L, your home will be more radioactive than 94% of US homes: The concentration of radon gas is not measured directly but rather by the radioactivity it produces. Testing is the only way to know your level of exposure. The shortest wavelength is ultraviolet radiation which causes skin cancer. EPA has drinking water regulations for more than 90 contaminants. The most substantial epidemiological study ever on the link between residential radon and lung cancer was published the University of Iowa in 2000. Their annual exposure is limited to less than 4 WLM (Working Level Months), equivalent to 33 pCi/L during their working hours. But at the same time, EPA has made it clear that the 4 pCi/L action limit is not a "safe" level and warned the public: Any radon exposure has some risk of causing lung cancer. Though radon levels in water aren’t usually high enough to significantly impact the levels of radon in the air, you can take steps to reduce the radon in your water, if necessary. When relaxing at home, we breathe in radon. At 4 pCi/L each liter of air contains 70,000 radon atoms. Although the 4 pCi/L level has become a benchmark for real estate transactions, it still carries considerable risks - equivalent to getting a chest x-ray or smoking 10 cigarettes each day. But less than 1% of the inhaled atoms get trapped and we thus accumulate in our airways about 600,000 radioactive particles every hour. It is difficult for people to accept that their home, a place that one looks to for security, is hiding invisible danger. Although the U.S. Congress has set the natural radon concentration outdoors as the target level for homes, approximately two thirds of homes exceed it.
