I have completed a quick survey of my now-dormant fusor chamber with a 2" NaI detector looking for signs of neutron activation of elements in the stainless steel housing.
To my surprise, there is no configuration of counter+chamber that does not count a little LESS than the counter by itself!! Obviously, what's happening is that the chamber is serving as a shield for the counter against background radiation. The greatest reduction (~18%) occurs when the chamber is place between the counter and the concrete floor. The smallest reduction (~7%) occurs when the chamber is placed directly above of the counter.
Obviously, my chamber is not very active...
