Measurement units, short and long term averages

Updated over a week ago

The Corentium Home is designed for LONG-TERM measuring of radon. 

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 monitor 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.

In the example below, the 1-DAY average is 0.51 PCI/L:

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 and this average updates once a day.

In the example below, the 7-DAY average is 0.37 PCI/L:

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. The long term average is updated once a day.

In the example below, the long term average is 0.35 PCI/L, which is the average over a total of 9 days:

The Long term average is the most important and accurate depiction of your radon levels, and that's why we recommend it's important to measure in one place for at least 30 days before moving the device if you want to monitor several rooms or locations.

But how do I know if my radon levels are good or bad?

We have outlined what the levels mean in the article:
