You should be able to buy an absorption test kit. For instance in the UK, you can pay £50, you get a couple of detectors to sit in your house for a few months and then you send them to a certified lab.
These kits are fine if you want to check or sell your house - in most cases the amount of radon in your house is determined by your local geology. If you pass an absorption test, it's unlikely you'll suddenly find dangerous levels of radon in the future.
The advantage of the real-time detectors is that they're real-time, but it's hard to prove that they're calibrated.

- verelo 9y agoRealtime sensor calibration is hard to prove, but proving that an absorption kit is a reliable reading also has it's challenges: In practice radon emissions vary dramatically throughout the seasons and based on rainfall, in particular in colder climates. Hopefully one day we see slab depressurization become standard in all houses with below grade construction, combined with a realtime sensor just like you would have a smoke alarm.

When I did Radon measurement for my house the guidelines for getting an accurate reading was to measure for 2 month between October and April to mitigate those factors.
- verelo 9y agoYep that certain does a decent job. I’ve been measuring for around 18 months now, my surprise finding is that only in the last few months has it gone up over 150 for the first time. I’d encourage you to do both if possible.
