Sounds like you've got a plan that can work, and of course we'd all like to see pix . If it shows you anything, please also make a control version (same but no Am in it) and see if there's something making them both move at once, for control. With the insane cosmic ray bursts we get here, I'd want to be sure it wasn't just that making it move.
For example, I have a 3He proportional tube for neutrons. It normally counts once or twice a minute on background. But on any given day, there will be some 10 second long bursts of many counts (thousands)...this tube doesn't see gammas, alphas...betas (unless they are insane energy).....just neutrons. I have it set so numb that a neutron source of about 1 mrem/12 hours doesn't count it at all -- it will only count if two more more neutrons hit it inside one tube response time (about 20us). We have that on an audio amp, and we thought it was broken the first few times that happened. Then we hooked up some more detectors and found them all going at once on those huge bursts -- all over the shop, so we must have been seeing secondary showers.
