As the lifetime of the thorium you have available is so long , the probability of an atom decaying is very small . In addition the transit velocity of an electron which is traveling with a velocity higher than the phase velocity of light in water, will be in a time frame undetectable to the eye, so the cerenkov radiation from that single electron will be in ...
