One More Radon Monitor Question

This page contains one additional monitor question from the public knowledge files. Even a small topic can be useful when the question points to a common homeowner concern: how to understand a monitor reading without treating one device, one short window, or one room as the whole story. American Radon Systems does not sell monitors or testing, so the guidance is educational. The mitigation side is the service path. If a monitor pattern remains elevated, changes after a system is installed, or makes an existing system look questionable, Bill can review the home, the fan, the suction path, and the foundation details that affect mitigation.

Is it better to get two cheap monitors or one expensive one?

For the radon side, focus on a reliable current reading and a clear mitigation path if the level is elevated. Real-estate paperwork, repair allowances, rental responsibilities, and closing decisions should be handled by the people managing the transaction. Bill can help with the practical radon part: what the number means, whether mitigation makes sense, and what a proper system would involve. If the reading is 4.0 pCi/L or higher, EPA recommends fixing the home. Between 2.0 and 4.0 pCi/L, EPA says to consider mitigation, especially if the space is used often.
