S_L is on the correct side of the issue here. We do not say 1mW lasers are safe to stare directly into because there are too many factors in play, even though they're several times below the threshold for damage. You don't really know the output of the unit until it is tested - first and foremost.
My DIY X-Ray unit puts out over 120R/hr (33mR/sec) of 45KeV photons. Yeah, at <5sec that's not too much to worry about for rare exposures. However, at 30sec you're talking about 1REM of exposure! That's plenty to cause a burn.
