seeing light flashes

[kearfott@srvr5.engin.umich.edu (Kimberlee Kearfott)]

Hi gang- this showed up on the medical physics list server. I remember
hearing accounts that astronauts on Apollo missions and folks who
inadvertantly stuck their heads into accelerator beams have seen light
flashes, but I cannot find a references to support this. Anybody got any
references?
