The EPA recommends that the average radon exposure rate not exceed 4.0pCi/L. In New Jersey, 30% of the homes tested are found to in excess of 4.0 pCi/L.

Other environmental exposures are regulated to reduce the lifetime risk of cancer to one in 100,000. The EPA lists Radon risk exposure to 4.0 pCi/L for a lifetime (18 hours per day) to cause 7 additional lung cancers in a thousand non-smokers or 62 additional lung cancers in 1000 smokers. The risk is considered linear which means even 2 pCi/L for a lifetime would cause 3 additional cancers in a 1000 non-smokers. See similar questions...

of our post mitigation test results are less than 2.0 pCi/l. The remaining systems are between 2.0 and 3.9 pCi/l. See similar questions...

There are several proven methods to reduce radon in your home, but the one primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside. This system, known as a soil suction radon reduction system, does not require major changes to your home. Sealing foundation cracks and other openings makes this kind of system more effective and cost-efficient. Similar systems can also be installed in houses with crawl spaces. See similar questions...

Answer this first by asking: Have you retested to confirm that the levels are actually too high? In other words, if a short-term test (2-7 days) was used, did you conduct an additional test and the average of the two tests taken or was the reading from a long term test taken for 90 days or more? Radon levels can vary from day to day so conducting one short-term test may not reflect the true level of your home. See similar questions...

If the test was short-term and below 10 pCi/L, retest in the same location with a long-term test device to determine the long-term concentration. If the initial test exceeds 10 pCi/L, retest in the same location with a short-term device. Radon mitigation should be performed if the average of two short-term tests or one long-term test is at or above 4 pCi/L. See similar questions...

Radon exposure is based on a combination of how long you are exposed and the radon level. In general it is not necessary to ventilate a house unless the mitigation system cannot be installed in the next few weeks and the radon levels are very high (greater than a hundred pCi/l). The best ventilation is leaving a basement window continuously open and/or a bedroom window open at night. See similar questions...

Radon is a naturally occurring gas which results from the decay of radio-active elements in the earth. In some circumstances it can be trapped and concentrated in a building where it can be harmful to health. You can find out if you are in an area of high risk from Radon by looking at the maps on the National Radiological Protection Board (NRPB)web site. You will also find details of how to get your home or workplace tested (free to homes in high risk areas). See similar questions...

Radon is a cancer-causing radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Any home can have a radon problem. In the U.S. it is estimated that nearly 1 out of 15 homes has an elevated radon level. See similar questions...

Yes. Radon gas levels in houses vary from hour to hour, from day to day and from season to season. These variations are mainly due to temperature differences, weather changes and house use throughout the year. Generally speaking, indoor radon levels are higher at night than during the day, and are also higher in wintertime when houses tend to be more airtight. Back to the Top See similar questions...

High Radon levels can be successfully reduced to below the national Reference Level at a cost, which is small compared with the value of a typical house. A potential purchaser of a house may ask for a radon measurement to be carried out, if the house is located in a designated High Radon Area. Back to the Top See similar questions...

The main source of Radon gas in houses with elevated indoor radon levels is generally the ground beneath the house. The radiation emitted from granite walls, fireplaces, or tabletops is insignificant. Back to the Top See similar questions...

Yes. Short-term radon gas measurements ranging from several hours to several days are possible, but are not suitable for determining the long-term average radon gas concentration in a house, which is what is required for comparison with the National Reference Level.
