Re: X radiation exposition

... Even then, that isn't sufficient since one must be able to measure any neutrons produced. In any case, your power supply sounds fusor capable so ... and be certain any fusor is properly grounded - read the FAQ's on the safety of high voltage for fusors (NEVER allow your transformer to float!) ...

Re: Neutron Scintillation Detector: start up work

Thanks Richard! Since my fusor puts out at least 3*10^4 neutrons/sec and I suspect a good bit higher I would hope that is enough; so, ... shocked by that ability.) But that system is solely used as a radiation safety detector system.)
