Are digital radon detectors better than charcoal test kits?
They solve different jobs. Kits are low-cost screening tools, while digital monitors track trends continuously and are better for long-term monitoring.
How long should I run a digital detector before trusting the reading?
Initial numbers appear quickly, but stable decisions should rely on multi-day trends and ideally a longer baseline in normal lived-in conditions.
Do I still need a lab test if I own a detector?
For many homeowners, a quality detector is enough for ongoing monitoring. A lab kit can still be useful as a secondary validation point.
Which detector is best for post-mitigation verification?
Users often prefer models with faster updates and easy trend visibility, such as the RD200, to check system behavior over the first days and weeks.
Can I use these monitors upstairs and in the basement?
Yes. Radon is often highest in lower levels, so start there, then rotate placement if you want a full-home profile.
