We have looked into adding a radon sensor but it is very difficult to get an off-the-shelf radon module in the market that is reasonably priced.

If any of you can recommend a module I would be very interested to hear.

Repackaging these sensors might be a better play than an OTS procurement model. Lots of people are making pretty packages for commodity sensors. Few are developing new sensor packages.
