I imagined that condensation should not be a problem. The Geiger counter was in a ~27 - 30°C environment before I went into the (quite a bit colder) basement. I would have to think of something to keep it at those higher temperature throughout the measurement, maybe a hair dryer? Cooling...

This may actually be an interesting experiment! Thanks for your ideas!

It could well be, if the radon or its decay products somehow stuck to my clothes or something. But wouldn't the reading change depending on how close I am to the detector? As I've said, I think that is unlikely. The radon would have to spread across multiple floors, through several doors, and...

I tried to find a good radon-map for my area, the best I could find lists the radon concentration of the air near the ground as '41-100 kBq/m^3', which is the second highest category. I am not really sure what that compares to in other parts of the world because the map only showed Saxony. No...

I can't really imagine how it should be trapped inside the detector. I even tried to blow air across the detector to replace any possibly contaminated air with no effect. But if I find some time I will do a more controlled experiment and write down the values, maybe this will us something. It...

Only due to the high humidity, but no drops of water or something like that. I tested this a second time this morning, paying extra attention to not touch any surface with the Geiger counter, not holding it in the hand I touched any of the walls before, removing any spider webs in the way etc...

Hi everyone! I'm new to this forum, so I hope my question fits into this category. Yesterday I wanted to check if I could measure any radiation from Radon in my basement with my Radiascan-701 Geiger counter which features a pancake-style probe that should be able to handle alpha, beta and...
