When you first start your Corentium Home 2, a message on the device display reads “First radon values in 24H”. Here’s why.
Why don’t I get radon level for the first 24 hours?
Your 24-hour radon average is calculated from the first 24 hourly radon samples taken by the detector. Once it has collected 24 hourly samples, it reports a first 24-hour radon average.
You might wonder, why don't we just look at the hourly measurements? Why use an average? Essentially this is because, unlike temperature, individual measurements can vary quite a lot from one hour to the next. This makes them misleading, or confusing if we look at them on their own. By calculating averages for every 24-hour period, we get a more consistent and representative indication of our exposure to radon.
What if my first average is in the POOR range?
Don’t panic. The health threat that radon poses is from exposure to elevated levels over a long time period of many years. High levels of radon do not pose an immediate health threat.
Consider that a short-term average, like the 24-hour average, is often NOT indicative of the risk radon poses in the room you are monitoring. Radon levels rise and fall, often in short cycles, so your true exposure is best represented by a longer-term average of several weeks or months.
Just keep monitoring and pay attention to the cumulative or long-term average your monitor is reporting. The additional weeks you take to build a more accurate picture of the radon threat are worth it to make a more informed decision about mitigation.
