What is the difference between your monitor and the test kits at my local hardware store?

Our monitor is an electronic continuous Radon Monitor and will monitor the Radon level in your home continuously. Self test kits purchased at a hardware store provide passive tests…these tests are not as reliable as electronic monitors. Many consumers pay the fee for the test and send the test to the lab with payment only to discover the results are inconclusive. If you are not involved in a real estate transaction… Why would you even consider a test, when you can monitor your Radon level 24 / 7 everyday!

Why should I monitor Radon, when I can simply test it?

A test is a snapshot of the Radon level in the home for a specified period of time. Radon levels change from season to season and year to year…. A test performed today would probably yield different results next week. It is safer and easy to deploy our electronic continuous Radon Monitor and have confidence that if your Radon level exceeds the 4.0 pCi/L action level the Radon Monitor will alarm.

My house was tested years ago, could my Radon levels change?

Most certainly, the EPA recommends testing for Radon every two years. Radon is a natural occurring gas and every home can have a detectable level, find out your Radon Level today!

I tested my home when I purchased it during the real estate transaction and the home passed. Why should I monitor the Radon now?

Whether your home has been tested and passed, or perhaps even has a Radon Mitigation system installed, the best method of checking any mitigation systems performance and to determine that the levels are still below the 4.0 pCi/L action level would be to monitor the home full time 24 / 7.

My home has a Radon Reduction (Mitigation) System, do I still need to monitor?

Radon Mitigation systems are often checked with professional testing equipment before giving the clearance that the system is working properly. The only way to really be sure the Radon levels remain below the 4.0 pCi/L action level would be to monitor on a 24 / 7 basis.

My home was tested a short time ago and it had levels above 4.0 pCi/L, is it too late to do something about it?

Apart from the risk of Lung Cancer, your home's value is at stake... Radon testing is becoming more common during a real estate transaction. Homeowners who do not address the issue of knowing their Radon level may be forced to deal with it when they become home sellers. It is never too late to address mitigating a high level of Radon. A healthy home is a happy home!

What is 4.0 pCi/L?

Picocuries per liter (pCi/l) is used to measure the amount of Radon in the air.

1 pCi/l @ 18000 radon atoms/liter @ 2.2 radon atoms decaying a minute/liter.

How many monitors do I need to test my home?

Most professional testers place a monitor in the lowest habitable portion of the home, and above crawl spaces and in slab on grade additions. However, these guidelines are for testing during a real estate transaction. We recommend testing in your basement usually the basement will result in the highest levels of Radon in the home. If your home is built entirely above a crawl space or a slab on grade, we suggest you place one monitor in the home in a quiet room toward the center of the home. This room would NOT be a laundry, kitchen, bath or closet. Bedrooms are preferred. Keep the monitor placed toward an interior wall.
