I agree that there is nothing to be concerned about (except possibly if you are using a high-res _color_ screen as a workstation). However, the fact that a CRT meets federal regulations (a) is not surprising and (b) doesn't mean shit. A few years ago when my group got the latest color screen to port our CAD software to, I took the time to look up the applicable regulations and do the proper unit conversions (units for radiation are a mess). It turns out that the regulations allow exposure equivalent to a chest X-ray every three or four weeks. Don't get me wrong, I doubt that there is any CRT anywhere that actually emits that much. It's just that the regulations are almost totally useless; and likewise the government that enacted them! --- Jef Jef Poskanzer jef@rtsg.ee.lbl.gov ...well!pokey "We find interference in others' affairs... most disgusting." -- Ayelborne
