For several years I have had a Geiger counter running in my house. Registrations is made by sound, a counter and a dial. Usually I can't hear it, but my guests do. But if the ticking sound changes I register. Usually the intensity changes less than +-5% measured over an hour. But now and then( maybe a few times a year ) I get an increase to 3-5 times normal intensity. Can stay like that for a few hours or return to normal within a few minutes. Last time this happen was just a few days ago. It went up to about 6 times normal for a few minutes. What might cause those peeks in registrations ?? Showers of cosmic radiation ? Solar eruptions ? Or a nuclear power station releasing something ? Any suggestion ? Regards John Rehn Sweden
