Seriously, I'd be inclined to dig out the geiger counter and check for ionizing
radiation in the area.  I know of one rock hound whos 'counter went wild in
his bedroom many years ago... turned out the Mexican tiles that formed the top
of his nightstand were "hot"...  also, I've heard many disturbing stories from
archaeologists, who, in recent years, have been getting interested in chemical
analysis of pot shards: Chaco Canyon in NM has supposedly produced some pottery
so "hot" it can't be stored where people normally are (and Indians were at one
time eating out of this stuff!)

Anyway, ionizing radiation can make phosphors glow just as well as electron
beams: the phospors are only interested in the right amount of energy, not in
what provides it!
