The First Alert RD1 is an EPA-listed charcoal-based radon gas test kit that allows homeowners to check their home, office, or school for dangerous radon levels. Simply place the sampler at the lowest point of the building for two to four days, then mail it to the included lab for analysis. Lab results are available within three to five business days of receipt, and lab fees are included in the kit price (except NJ state fees).
