They most likely found a picture of someone using a Geiger counter to detect Radon by some of the radioactive daughters that seem to be present with radon. Not an accurate way but it was tried in the past. A nice treatment for a dry drain in the case of safety showers or seldom used floor drains is to use vegetable or mineral oil to partially fill the drain since it will sit on top the water and slow the evaporation.

The photo actually looks like it is a CGI still, perhaps from a video game or similar.
I really appreciate the chemical safety headlines, keep please them coming.
The photograph in the press release (see link below) about the dry drain incident caught the eye of our RSO. I must admit this is the first time I've seen anyone using a Geiger counter to investigate an odor!
