How technically challenging is this? I would expect that all weather monitoring stations are already kitted out with all the detectors they can bolt onto the air intake. CO2, oxygen, air pressure, humidity, radioactivity, love in the air, whatever.
If you already have the facility why not record everything? Or is a good radiation detector a $$$$ investment?
GMC Geiger counters have a usb port, which lets you upload real time data: https://www.gmcmap.com/

I'd guess you still need to maintain them and confirm their accuracy. Tuning a Geiger counter seems more niche then tuning a humidity sensor.
I don’t know… we have radioactive elements with a very long half-life, which I assume would be great for calibration: somewhat safe and low activity, so good match for atmospheric concentrations of common radionuclides
A single sensor is cheap. Thousands and tens of thousands of installations with a dozen sensors, not so much.
