You've been monitoring your radon levels for a while, but what do these numbers mean?

Should you be worried?
Is it necessary to install a radon pump?
Should you just open the window more often?

We recommend you measure in one location for at least 30 days, to understand the behavior of radon in your environment and to obtain enough data. 

The longer you measure for in one location, the more accurate your readings will be. You should always consider your long term average when deciding to pursue radon mitigation action.

Radon levels fluctuate naturally. If you see an irregularly high reading of radon one day, it is generally nothing to be alarmed by. However, if after some weeks of monitoring you see consistently elevated radon levels, you'll want to keep a close eye on how they continue to evolve.

The chart below offers guidelines on radon levels (in both picocuries and becquerels for imperial/metric measurement system) and what action to take in response:

Radon monitors can also be used to evaluate the effectiveness of mitigation systems, ensuring that radon levels are reduced to safe limits.
