TER™ Technology: The Most Advanced Radon Test Available
Open windows, inclement weather and high humidity can significantly reduce radon levels during testing leading you to believe your radon levels are safe when they may not be. TER™ testing uses five scientific sensors, real-time weather and machine learning to detect conditions that lead to inaccurate radon results. We include free TER™ testing with every radon test we do. But, it doesn't stop there. We only use Radstar radon monitors because they make the most accurate radon machine on the market (see below).
The EPA published a study in 2014 on the effectiveness and accuracy of disposable radon test kits in a controlled radon environment. See full report. They found only 40% of alpha track devices, 64% of activated charcoal, 61% of liquid scintillation and 75% of electret ion tests passed. Passing means the results were within +-25% of the real value.
Sun Nuclear Radon Monitors
Sun Nuclear is the leading radon machine used for radon testing. As reported by the company, the accuracy is only +-25% of the actual radon levels.
RadStar Radon Monitors
RadStar radon machines (as reported by manufacturer) have an accuracy of +-10%. Thats over twice the accuracy of the leading radon machine and all radon vial testing methods.
