Aranet Radon One – Continuous radon detector

A detector that stays in your home and shows the radon level at all times. No return to the laboratory.

Aranet Radon One — continuous radon detector

Radon changes with weather, heating and the seasons. A 4-day or 91-day kit is a lab snapshot. This unit stays with you and tracks the concentration over weeks and months. It also helps confirm that a mitigation system is holding the level down.

Where to place it

In the lowest lived-in room, often the basement, then in a bedroom or living room. Set it at breathing height, away from doors, windows and vents.

Health Canada guideline: 200 Bq/m³. WHO reference: 100 Bq/m³. If the average stays above these levels, mitigation is recommended. Need a certified lab report instead? Use the 4-day or 91-day detector.
