> Radon was mentioned on the project website, yes technically radon decay products are detectable but pracfically a Geiger tube is reacting only to terrestrial, cosmic, and other sources of radiation, not anything to do with radon.
To measure radon (say in a cellar), you'd typically take some dust filter or filter foam, attach it to a fan and circulate the cellar air through the filter, then the radioactive dust collects in the filter, and one can measure higher doses more easily.
