Water might occur to you, and food, but since most of us carry enough fat around the waist line to last a few days, nutrition usually comes last. The health risks of polluted air inside our houses — a year-round concern — can be greater in the winter, health and environmental officials say. Tobacco is the main cause of lung cancer and 90 percent of lung cancer cases are caused by smoking. I am selling my house and in this process, my house was tested for radon using a mail-in kit.Taking the necessary actions against the radioactive gas that cannot be seen, smelled, or tasted requires getting homes tested for elevated levels.

Smoke in the kitchen, mold in the bathroom, dust in the living room. A common source of exposure to radon that can be avoided is exposure in the home, yet only one in five homeowners has actually tested for radon. It is produced when uranium decays and works its way up through the soil into the atmosphere. It is the second leading cause of lung cancer and the leading cause of lung cancer in non­smokers.

There is no acceptable, safe level of radon.


The Truth About Granite, Radon, And Radiation

As you breathe, radon and radon decay products enter your lungs.

Outdoors, radon is quickly diluted by the atmosphere and poses no problem. You won’t have to tear down your home or move out if there is a radon problem. If you are planning to build a new home, ask your contractor to install a radon mitigation system during construction. Building the system in up front costs much less than adding it after the home is built. If the second test has similar results, it is best to contact a trained, certified radon mitigation contractor for help. The contractor will probably use a combination of sealing techniques and a system that pulls air from beneath your home by using a vent stack and exhaust fan and vents it above the eave line. It is responsible for a reported 21, 000 deaths per year. Radon is a radioactive gas that forms when naturally occurring uranium in granite bedrock decays into radium. This radium then decays to radon, a colorless, odorless gas.

Radon is not harmful outside, but it can build up to damaging levels inside. The air pressure inside your home acts as a vacuum, helping to pull radon up from the soil beneath. How do you know if you have high radon levels in your house? Radon levels can vary from house to house. The only way to know whether or not you are being exposed to high radon levels is to get a test kit. They contain a charcoal sponge that will soak up any radon in your home. Your results will be mailed back to you a short time later. The website also has an instructional video on how to properly use the radon test kit. Just as with tobacco smoke, not everyone exposed to radon will develop lung cancer. However, if you are concerned or would just like some peace of mind, radon test kits are an easy solution. She didn’t smoke, and she didn’t have a family history of lung cancer. What she had was prolonged exposure to high levels of the radioactive gas radon. Radon is an invisible and odorless gas that breaks down from uranium, granite, shale and phosphate and seeps into soil and water. A simple test can detect radon and fairly inexpensive fixes can ease the problem.

I didn’t want to continue to live in the house until it was mitigated,” the 75-year-old retired history teacher said. The amount of radon seeping up from the earth and settling in houses varies by region. Last year, three out of about a dozen houses she sold had elevated radon levels.

Her doctor noticed a lung spot and sent her for more tests.

Additional tests in her basement and upstairs bedroom showed higher levels.

Today, she is short of breath but her prognosis is good. They plan to do more tests and determine if anything else is needed to lower the gas levels.

Radon occurs naturally in mines, caves and water treatment plants.

Radon that creeps out of the ground can enter houses and other buildings through cracks in concrete, floor gaps, small holes in walls and drains.

Because radon is a natural part of the environment, there’s no such thing as a “0” level. The program educates the public regarding radon health risks, testing, and mitigation, and distributes complimentary radon test kits.

Radon results from surrounding areas (n 2600) were also tabulated. Elberton granite fit the model of higher radon (and uranium) in the granite relative to the host rocks.

But he stopped in his tracks in the kitchen, which had richly grained cream, brown and burgundy granite countertops.

The granite, it turned out, contained high levels of uranium, which is not only radioactive but releases radon gas as it decays.

A geology instructor at a community college, she realized belatedly that it could contain radioactive material and had it tested. The technician sent her a report indicating that the granite was emitting low to moderately high levels of both radon and radiation, depending on where along the stone the measurement was taken. Sugarman’s kitchen, the readings were 100 picocuries per liter. In her basement, where radon readings are expected to be higher because the gas usually seeps into homes from decaying uranium underground, the readings were 6 picocuries per liter.

The limit of additional exposure set by the commission for people living near nuclear reactors is 100 millirem per year. Sugarman’s might add a fraction of a millirem per hour and that is if you were a few inches from it or touching it the entire time. Children and developing fetuses are vulnerable to radiation, which can cause other forms of cancer. She replaced them with another type of granite. They are sold at hardware stores and online. The middle spectrum is of radon, while the outer two are of helium (added to calibrate the wavelengths). Radon is appreciably more soluble in organic liquids than in water. Radon is a member of the zero-valence elements that are called noble gases.

It is inert to most common chemical reactions, such as combustion, because the outer valence shell contains eight electrons.

Its four first products (excluding marginal decay schemes) are very short-lived, meaning that the corresponding disintegrations are indicative of the initial radon distribution. If a closed volume is constantly supplied with radon, the concentration of short-lived isotopes will increase until an equilibrium is reached where the rate of decay of each decay product will equal that of the radon itself.The equilibrium factor is 1 when both activities are equal, meaning that the decay products have stayed close to the radon parent long enough for the equilibrium to be reached, within a couple of hours.

Because of their electrostatic charge, radon progenies adhere to surfaces or dust particles, whereas gaseous radon does not. The equilibrium factor is also lowered by air circulation or air filtration devices, and is increased by airborne dust particles, including cigarette smoke. The rate of deposition of this radioisotope is weather-dependent. Not all granitic regions are prone to high emissions of radon. Being a rare gas, it usually migrates freely through faults and fragmented soils, and may accumulate in caves or water.

Radon concentration varies greatly with season and atmospheric conditions.

Residues from the petroleum and natural gas industry often contain radium and its daughters.

The sulfate scale from an oil well can be radium rich, while the water, oil, and gas from a well often contains radon. Radon mostly enters a building directly from the soil through the lowest level in the building that is in contact with the ground. High levels of radon in the water supply can also increase indoor radon air levels.

The ionizing radiation causes the formation of free radicals , which results in genetic and other cell damage, resulting in increased rates of illness, including cancer . The gold seeds were produced by filling a long tube with radon pumped from a radium source, the tube being then divided into short sections by crimping and cutting. The gold layer keeps the radon within, and filters out the alpha and beta radiations, while allowing the gamma rays to escape (which kill the diseased tissue). Radon and its first decay products being very short-lived, the seed is left in place. After 12 half-lives (43 days), radon radioactivity is at 1/2000 of its original level. For this reason, it has been hypothesized that increases in radon concentration is due to the generation of new cracks underground, which would allow increased ground water circulation, flushing out radon. The generation of new cracks might not unreasonably be assumed to precede major earthquakes.

It disperses rapidly, and no radiological hazard has been demonstrated in various investigations.In recent years, the average annual exposure of uranium miners has fallen to levels similar to the concentrations inhaled in some homes.

Radon, like other known or suspected external risk factors for lung cancer, is a threat for smokers and former smokers.

The risk is from smoking, compounded by a synergistic effect of radon for smokers.

Small cell lung carcinoma, which practically only affects smokers have high risk from radon. But the group that had been exposed to passive smoking at home appeared to bear the entire risk increase, while those who were not exposed to passive smoking did not show any increased risk with increasing radon level. Optimum conditions for radon release and exposure occur during showering. In some countries these tests are methodically done in areas of known systematic hazards.

Radon detection devices are commercially available. Digital radon detectors provide ongoing measurements giving both daily, weekly, short-term and long-term average readouts via a digital display. Short-term radon test devices used for initial screening purposes are inexpensive, in some cases free. The kit includes a collector that the user hangs in the lowest habitable floor of the house for 2 to 7 days.

Long term kits, taking collections for up to one year or more, are also available. Another method of reducing radon levels is to modify the building’s ventilation. Generally indoor radon can be mitigated by sub-slab depressurization and exhausting such radon-laden air to the outdoors, away from windows and other building openings.

A vent pipe and fan are used to draw the radon from under the sheet and vent it to the outdoors.
