Understanding Radon Testing and Expert Recommendations
A test must be conducted to determine if you need a radon mitigating 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.
To make passive radon testing devices function, you don’t need power. 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 include continuous radon monitors and continuous working level monitors, both of which make active testing more expensive.
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. The radon testing device you use must be obtained from a qualified laboratory. The greater your radon exposure, the higher your risk of getting lung cancer. Hence, a radon-certified contractor installing a radon mitigation system in your home can practically save your family’s life.
Radon amounts in the air are often measured in picocuries of radon per liter of air (pCi/L). Sometimes, the results of a radon test can be expressed in Working Levels (WL) rather than pCi/L. In a typical house, 0.016 WL is equal to around 4 pCi/L.
A radon abatement system should be in order at such a level. The U.S. Congress has set a long-term goal of keeping indoor radon levels lower than outdoor levels. Around pCi/L is generally found in outdoor air. If one long-term test of your home or the average of two short-term tests reveal radon levels at 4 pCi/L (0.016 WL) or higher, EPA recommends mitigating measures.
With current technology, most homes’ radon level can be lowered to 2 pCi/L or less. Radon mitigation can also be considered for a radon level reading of 2 pCi/L to 4 pCi/L. A short-term radon test stays in your home for 2-90 days, while a long-term test can be in your home beyond three months. Each radon test should be taken for at least 48 hours. With a short-term test, you can expect faster results; with a long-term test, you will get a clearer idea of your home’s year-round radon level, and whether radon mitigation is a must in your case .
EPA Radon Testing Recommendations
Two radon testing categories are recommended by the EPA. 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.
