Questions, answered

Do I need an app or Wi-Fi to use it?
No. The Corentium Home displays radon levels directly on its own screen and runs on AAA batteries. There is no app, Wi-Fi, or subscription.
What radon level should make me act?
The EPA recommends fixing homes at or above 4 pCi/L; the WHO uses a stricter reference of 100 Bq/m³ (about 2.7 pCi/L). Any reduction lowers risk. Source WHO radon fact sheet ↗NCI radon fact sheet ↗
How soon do I get a reading?
A short-term average appears after 24 hours, with 7-day, 1-month, and long-term averages building over time. Long-term readings are most reliable since radon fluctuates.
