me356 reports intense ionization experienced up to 3 meters away from the his test reactor, heavy enough to disable his test equipment. Such heavy ionization could effect the electrical activity in a susceptible brain.
IMHO, such ionization might be produced by heavy muon and/or RF production.
I have not detected heavy RF radiation. And it is easy to shield with thin metal. Such radiation easilly go through thin metal. It affect slightly to cheap radios.
In brain there exisit two types of magnetocytes, which contain magnetosomes, which contain small paramagnetic magnetite crystalls up to some billions in everybody brains. These crystalls effectively shields inner brains from RF radiation.. (see "god helmet")
Only magnetic fields go through brains. I have not detected strong magnetic fields near reactor.
What is "heavy muon"? Heavy electron? positive/negative muon?
