Plus: what do my measurements mean?

Measurement units, short and long term averages

Updated over a week ago

How are the measurements taken?

Before we launch into how your Corentium Home's measures radon, please note there are 2 ways that radon is measured, and it basically depends where you come from :)

  • PCI/L is the imperial system (US) for measuring radon and stands for picocurie per liter of air

  • BQ/M3 is the metric system (EU/CA) for measuring radon and stands for bequerel per cubic meter

In this article, the examples we use are in PCI/L.

From the moment you calibrate your Corentium Home, the radon sensor will begin to take measurements once every hour. Each hourly measurement taken by the device is compiled on a rolling 24hr basis to give you the following readings:

1. Short term average - 1 DAY (last 24 hours) - updated hourly

The 1-DAY average only provides a rough estimate of the radon concentration in the last 24 hours. It has limited accuracy and should not be used as a basis for taking remediation action. The 7-DAY average has better accuracy and is the shortest period of time that gives a reliable indication of your radon exposure.

2. Short term average - last 7 DAYS

Please note: the 7-DAY average will only appear after the device has collected 7 days worth of data.

3. Long term average - since the device has started measuring this current period

To check how many days you have been measuring for in total this period, press the MODE button at the back of the device and it will show total amount of days on the display.
