Household Environmental is ready to help you test your property for radon. We are ready when you are! Our company provides the fastest and most accurate testing services available. Our various testing equipment allows us to provide every type of radon test available.
There are several types of short-term devices that are used for testing the level of radon in the air. A short-term test is typically performed over a two-to-seven-day period. This test gives an indication of levels that can be expected over the long term. We typically perform long-term tests (90+ days) immediately following the installation of a mitigation system. The most popular short-term devices in the New England area are:
A charcoal canister is a small, metal, disc-shaped device. When the test starts, the canister is opened and placed:
- in an interior area closest to the soil, typically the basement here in the Northeast
- about 2 feet off the floor
- in an undisturbed area
- under closed-house conditions
The canister is left in the basement for two to seven days. At the completion of the test, the charcoal canister is sealed up and mailed off to a laboratory for evaluation. The results are available a few days after receipt by the lab. It is important that once the test begins that the protocol be strictly followed to obtain the most accurate information. For example, a test kit evaluated 30 days after the specified exposure time will have a much lower radon reading than one that was evaluated immediately following the two-to-seven-day test period. This is because the test is evaluating radon, which has a half-life (when its radiation is strongest) of 3.8 days. The longer the test evaluation is delayed, the lower the level that will be detected. The main advantage of this screening test is its low price. Several disadvantages are that:
- it is easily tampered with
- only offers an average radon level reading
- may not be accurate
- takes a long time to receive results as compared to other methods.
Liquid Scintillation Vials
Liquid Scintillation A vial with a small amount of activated charcoal is placed in the lowest livable area of the home. Radon becomes trapped in the charcoal. Upon completion of the test, a lab places the charcoal into a second vial full of liquid scintillant. After approximately 4 hours in the liquid, the radioactive decay of radon is visible through light flashes. The light flashes are counted with a device, rendering the actual radon level in your home.
Continuous Radon Monitor
A CRM is a computerized device that takes a radon level reading once per hour. The CRM has a similar testing protocol as the charcoal canister. There are several major advantages to this method:
- results are obtained immediately after the completion of the test. A hard-copy printout of hour-by-hour readings, as well as an average, is immediately available to you
- the CRM has a tamper-detection mechanism. If the device is disturbed at all, we are notified through the printout
- Results are much more accurate than charcoal canisters
CRM testing is more expensive than charcoal canister testing, yet the improved accuracy as well as peace of mind typically make the cost worthwhile.
Household Environmental highly endorses the use of the CRM method of testing during real estate transactions. CRMs give you instant results. CRMs are also more resistant to tampering and are more accurate than charcoal canisters.
E-PERM® E-PERMs are the most popular of all the radon detectors submitted to the U.S. EPA for its Radon proficiency Program. They're also the most accurate. Since 1991, more than 90% of the E-PERMs submitted have "passed" the EPA's performance tests...even more than the electronic Continuous Radon Monitors. A true integrating detector, the device can measure fluctuating radon concentrations regardless of extreme temperatures or humidity. The U.S. Postal Service and several branches of the U.S. Armed Forces have chosen E-PERMs for surveys of public properties in the U.S. and overseas
Household Environmental uses the E-PERM System as our preferred method for radon measurement, offering our clients instantaneous results upon completion of testing.
To schedule a test, simply contact us at (866) 86-RADON
. When calling, please have the following information available:
- Property location
- Type of property (single family, etc.)
- Basement, slab-on-grade, crawl space?
We maintain a large number of testing devices and are typically available to begin testing the day after you contact us. Sometimes we are available the same day. We will do everything we can to accommodate you. We maintain early morning, afternoon and evening appointments as well as weekends. Your satisfaction and your peace of mind are important to us.
What It Costs
We do our best to keep your cost for testing among the lowest in the region. Charges in the Northeast typically range from $150 up to $225 for testing with a Continuous Radon Monitor. We keep our prices low as it:
- Saves you money
- Promotes a clean and healthy living environment.
Our charge for a 48-hour test is $110. Additional days, though not normally required, are $50 per day. Our testing includes two trips to your property (setup and pickup) and a hard-copy printout of the result and what it means.
