A continuous radon monitor sits quietly in a basement or crawlspace, sampling the air every hour to track this odorless radioactive gas. It displays real-time readings and logs data over days, helping you see if levels spike after rain or during winter when windows stay shut. Some models sound a warning when radon exceeds safe thresholds, giving you actionable info before it becomes a health concern.
