A test is necessary to know whether your need a radon mitigation system. Considering that radon is invisible and cannot be smelled, you need special equipment to know if it is present.
There are two types of radon tests, depending on the devices employed – passive testing and active testing.
Power is not required to make passive radon testing devices work. Such devices can include alpha track detectors, electret ion chamber detectors, charcoal liquid scintillators and charcoal canisters. Passive radon devices are generally cheap in cost, whether they are meant for short-term or long-term use.
As opposed to passive testing, devices used for active testing testing devices, which provide hourly as as well as full test readings, need power to run. These devices, which include continues radon monitors and continuous working level monitors, tend to make this type of testing more costly.
What Exactly Is Radon Testing?
It’s good to approach a state or local official to gain knowledge of the differences among various radon devices and what’s best for your particular needs and requirements. Make it a point to obtain your radon testing device from a qualified laboratory. Radon exposure can increase a person’s risk of getting lung cancer. Therefore, by hiring a radon-certified contractor to install a radon mitigation system in your home, you are saving your family’s life.
Radon amounts in the air are often measured in picocuries of radon per liter of air (pCi/L). In certain cases, Working Levels (WL) instead of pCi/L is used. In a regular home, 0.016 WL is equivalent to bout 4 pCi/L.
A radon abatement system should be in order at such a level. The U.S. Congress is aiming to keep indoor radon levels less than outdoor. Outside air normally has around 4 pCi/L. EPA recommends mitigation measures if you get a result of 4 pCi/L (0.016 WL) after one long-term test or as an average of two short-term tests.
Present technology allows the reduction of most homes’ radon level to 2 pCi/L or even less. For a 2-4 pCi/L radon level reading, you may consider radon mitigation as well. For a short-term radon test, expect it to remain in your house for a minimum of 2 days and a maximum of 90 days; for a long-term test, you can expect the period to extend beyond three months. Each radon test should be taken for at least 48 hours. Quicker results can be expected from shorter-term tests; longer term tests, on the other hand, give you a better understanding the average radon level of your home throughout an entire year, and tells you whether a radon abatement system is necessary.
Radon testing is recommended by the EPA in two categories. One is for homeowners whose house is not for sale, and the other is for radon testing and reduction in real estate deals. One is for radon testing and reduction in real estate deals, and the other is for homeowners with no intention to sell their houses.
