what is a safe level of radon in water

Operated under a … Radon produces tiny radioactive particles in the air we breathe. Radon is a naturally occurring radioactive gas that can cause lung cancer.You can’t see or smell radon. A Curie is a unit of radioactivity equivalent to 1 gram of radium and the prefix "pico" means a trillionth. 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. The President's Cancer Panel issued its "Reducing Environmental Cancer Risk: What We Can Do Now" in 2010. 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. deaths caused radon in the US each year. At 4 pCi/L each liter of air contains 70,000 radon atoms. As the US EPA explains, there is no safe level of radon, a radioactive gas which causes lung cancer, the No. High levels of radon can cause lung cancer, particularly for smokers and ex-smokers. Find Radon Zone and Radon Information Near You. Setting the limit at 4 pCi/L benefits (but does not necessarily save) only 30% of the 21,000 people that die each year of radon-attributed lung cancer, while a lower limit of 2 pCi/L would benefit 50%. Radon is the "silent killer." Sunshine is a radiation. 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. Read More (Radon causes 26% of lung cancer deaths among non-smokers.). The lower the radon level in your home, the lower your family's risk of lung cancer. The average (mean) radon level in US homes is 1.25 pCi/L, or three times higher than the average level outdoors. 1-800-644-6999*– Radon Fix-It Hotline for general information on fixing or reducing the radon level in your home. There are several types of ionizing radiation: Radon decay chain offers a full menu of ionizing radiation: alpha and beta particles, and gamma rays. The shortest wavelength is ultraviolet radiation which causes skin cancer. 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. The long-wave radiation is infrared and it warms the skin. and cosmic radiation (photons, muons, etc.) Radon Gas Is All Around Us. Save a life. 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. Cosmic radiation consists of a variety of very energetic particles, including protons, muons, and neutrinos, which bombard the earth from outer space. In the metric system, radon concentration is expressed in Becquerels per cubic meter (Bq/m3). There is No Safe Radon Level. Radon causes more deaths than fires, drownings, and airplane crashes combined. The high "action limit" reduces the number of lives saved. Learn more about the results of the Federal Radon Action Plan and launching the expanded National Radon Action Plan. (EPA). 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. 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. Remove radon from the water using granular activated carbon. The Environment Protection Agency was given the task of developing practical guidelines. An official website of the United States government. Unfortunately, that's not possible. The Miners Safety and Health Act (MSHA) covers underground miners. For more info visit short-term vs. long-term radon test kits. EPA Action Level Buying or Selling YOUR HOME? Short-term radon measurements are often more than a factor of 2 different from the real long-term average, and sometimes more than a factor of 4 different. One Becquerel equals one radioactive disintegration per second. 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. But less than 1% of the inhaled atoms get trapped and we thus accumulate in our airways about 600,000 radioactive particles every hour. 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. It has enough power to knock out electrons from atoms and convert them to electrically charged ions, which can damage the large molecules of living cells. The Kentucky Radon Program encourages continuous education on radon gas. The best radon level measurement would be zero. When relaxing at home, we breathe in radon. People spend most of their time at home - on average 70%, but more in case of women and particularly, children. Radon can also enter the home through well water but usually carries little risk in Kentucky. Be informed of the dangers of radon & rely on a radon professional.
