Long Term Radon Test Kit

Buy one of our long term DIY radon test kits and know your home's radon levels all throughout the year. This test will remain in your home for more than 90 days, in contrast to the short term radon test kits that take only a few days. This extensive amount of time enables for a detailed and precise analysis of your home's everchanging radon accumulations.

A long term radon test kit is typically purchased after acquiring some history of the building's radon levels. This means there isn't an immediacy to the results, but moreso a desire for thorough testing. A long term test is a great way to verify to what extent a radon mitigation system is working.
