What is Radon gas?
Radon is a radioactive gas. It is the result of a natural breakdown of uranium in the ground, including soil, rock and even water. This gas seeps into a house because most homes periodically have negative air pressure. In other words, they are sucking in air.
Testing for radon is not a test to determine whether there is or is not radon in the house, but instead it is a test to determine how much radon exists. It is also important to understand that any home is susceptible to a radon problem. This includes homes with or without basements, old homes, new homes, etc. The EPA (Environmental Protection Agency) has indicated that when a person breathes air containing higher concentrations of radon, they have an increased risk of acquiring lung cancer.
At the present time the EPA has recommended efforts to reduce radon levels in a home if testing indicates that the levels are currently at or above 4.0 pico Curies per liter. Some questions have been raised recently about whether the EPA intends to lower the "accepted level", but at the present time 4.0 pico Curies per liter remains the threshold level.
The EPA has also indicated that radon testing should be performed under "closed house" conditions. Specifically, all windows and exterior doors must be closed at least twelve hours prior to the start of the test, and also for the duration of the test. Testing lasts a minimum of forty-eight hours. Normal "in and out" traffic is allowed during that time, but the doors and windows must not be left open. Once again, it is important to understand that EPA establishes these rules in order to ensure accurate testing. All windows must be kept closed during the test, not just those windows in the immediate vicinity of the testing device. This is basically done to simulate how the house normally is (on average) throughout the year.
In regards to the use of air conditioners we would offer that central air conditioning systems can be used during radon testing since they do not allow for the free exchange of air between the exterior and the interior. Some window and wall mounted air conditioning units do not assure conformance with closed house conditions and, as a result, in many cases window-mounted air conditioners should not be used during radon testing.
Where is the test done?
According to the EPA, radon testing should be performed in the lowest livable level of the home. In most cases this means that the basement becomes the test site, assuming that it is a full depth basement. Whether the basement is currently finished living space or not, it is considered a livable level even if the basement does not have an abundance of headroom. Crawl spaces would not meet these criteria. In many old farm houses basements are of minimal depth and, as a result, could not be used as workshop space or "livable space". In these instances the first floor would then be tested.
The radon testing device should be placed in a somewhat central location of the lowest livable level. It should be placed an appreciable distance above the floor (typically at least 20 inches). It should not be placed directly adjacent to an exterior wall, near windows, near venting appliances (furnaces, water heaters, clothes dryers, etc.), in a closet, or next to a drainage crock or sump.
There are various testing devices that can be utilized for radon screening. Charcoal canisters are the simplest type of testing device. They are accurate, but they have their limitations and can be prone to false-positive readings in some situations. They are clearly not tamper-resistant. Most reputable radon testing firms utilize electronic monitors. These monitors take air samples continuously throughout the duration of the test period, measuring the levels of radon in the air during the test. The levels of radon will vary throughout the test, and the final result is the average level during the test. The highly accurate monitors that are utilized by our office also monitor temperature, relative humidity and barometric pressure. In addition, the monitors have a tilt-detecting mechanism. This provides some tamper-resistance.
It is important to understand that the radon levels in a home vary over time. In fact, the levels vary from hour to hour, let alone day to day, week to week or month to month. As a result, the screening tests that are performed are essentially a forty-eight hour "snapshot". A similar test performed at a different time in the same house will usually render a slightly different result, although it would probably be a result in the same range as the first result. There have been times when we have performed tests that have resulted in radon levels just above the 4.0 piCu/l threshold. Sometimes, buyers or sellers will opt for a second test. The second test result might be higher or lower than the first result. This is not because one test is more accurate than the other, but instead because the tests were performed at a different time. One logical approach would be to average the two test results to determine the average level of exposure in the house over the two 48 hour snapshots.
What do you do if your radon level is over 4.0-
Active radon mitigation systems are routinely installed when testing shows radon levels above 4.0 pico Curies per liter. These systems are relatively easy to install, and the cost of operation is minimal. Essentially, most radon mitigation systems provide a means to suck air from beneath the basement or slab floor and exhaust it to the exterior through the use of a simple PVC pipe and an in-line fan.
Radon levels are quite unpredictable, and it is not possible to predict with any appreciable accuracy what the levels of radon might be in one home versus another. One house on a street may have a level of radon higher than 4.0 and the house across the street or next door may have a reading below 4.0.
For more information visit this website:
Any individual or firm performing radon tests must do so in concert with an approved and licensed laboratory and all testing devices must be calibrated and approved for use. You should specifically ask anyone under consideration for radon testing whether their testing equipment and protocol meets these criteria.
This is an example of what a testing device looks like. You can also buy home kits.

*There must be a written, binding contract to purchase a property in effect on April 30, 2010. The purchaser will have until July 1, 2010 to close.
Frequently Asked Questions:
Q: I am an existing homeowner. On October 25, 2009 I signed a contract to purchase a property. I have lived in my current home for more than five consecutive years and am within the new income limits. I will close on November 25. Will I qualify for the new credit?
A: YES. The existing homeowner credit goes into effect for purchases after the date of enactment (when the bill is signed). There is no reference to the date of the contract for the new credit. The provision looks solely to the date of purchase, which is generally the date of settlement.
Q: I am an eligible first time buyer. I entered into a contract to purchase on November 1, 2009. Do I have to close before December 1? How does the extension affect me?
A: You do not have to close before December 1. Due to the extension it is as if the November 30 deadline never existed.

In a normal market a bank will repossess a property a usually process it through a listing agent within 30 days. Today with roughly 400-500,000 properties repossessed over the past year, they are not yet on the market.
Lenders and servicers office explanations as to why it is taking longer to process foreclosed properties that it has in the past:
- Many of the properties have title issues that need to be resolved
- Many of the properties are in states of extreme disrepair
- A number of states have strict redemption-rights periods which prevent the lender from reselling the property.
- A few states have extended the length of eviction proceedings
- The volume of REO's (foreclosed properties going into the MLS) has slowed down the process; there will be roughly 10 times the number of REO's this year as in the last "normal" year, 2005
There are many agents and buyers waiting for these potential "bargain" properties to come on the market. The banks often price them according to market condition but are also willing to take less than a homeowner to increase their chance of unloading the property and saving as much money as possible.
