Any of you guys monitor radon in a building?
Looking for a sensor that can measure radon with 4-20ma / 0-10v output and not having much luck.

We have a few homes that were built in an area identified as a Radon Hot Zone.
We were required to add forced ventilation into the crawl space.
But no requirement to monitor.
Most of the home buyers probably didn’t read the mouse print of their purchase agreement, and have no idea the blowers are in the crawl.
There was no requirement to supply any alarms to notify the residence if the blowers fail either.
If anyone knows of a good monitoring system for Radon; I would be interested in that info as well
I found this other pdf titled The State-of-the-Art in Sensor Technology for DCV. It's a bit dated (2005), but it has some good info on various emerging sensor technologies at that time.
Radon starts on page 70, and there's a nice table on pages 73-74 with various different sensors available at the time. It seems like the majority have a rs-232 interface.
The paper also mentions a DCV system in a lecture theater in Hong Kong using radon along with CO2 as a controlling variable.
I am just wondering if you had any success finding any Radon monitoring equipment that could be connected to a BAS. I have a customer with the same requirements that you mention in your original post. I have been looking and am not having much luck. In this day with all the concerns for IEQ i would have thought there was something readily available. Any help you can offer would be appreciated.
