Jeff's setup may be more sensitive to radon than Alan's. The NaI detector that Alan used is only sensitive to gamma, and not beta. Radon decay chains are primarily alpha and beta emissions. With the foil wrapped around Jeff's GM detector, he probably does not have much alpha sensitivity, but he will still have beta sensitivity - which could come from radon. Beta and alpha sensitivity can be evaluated with check sources. If Jeff is in the same area as Alan, he could borrow Alan's check sources, but I am not sure if Alan has a beta source. A good 24 hour background collection would also be useful as a null test to look for radon caused variation.
