UV from AR-1 glow lamp - danger?

  1. I have a GE AR-1 Argon glow lamp I'm using as a nightlight in my bedroom.
    I noticed the other night it produces enough UV to make white sheets and
    clothes fluoresce (optical dyes in laundry detergent).

    I can't imagine this small lamp producing enough UV to be dangerous, but
    thought I'd check. Anyone?

    Thanks DS

    Cotton fluoresces from radiation in the area of 350-370A and this
    radiation is not *inherently* dangerous, and is used in blacklights.

    Dangerous radiation starts in the ballpark of 300A and below. For a
    quick (though not scientifically reliable) test, you might try putting
    your sweaty palm against the little light, leave it against the
    radiation for a minute or so and then smell your palm. If it smells like
    funny, like burned steak, there's radiation that causes the death of
    epithelial cells and that, in and of itself, is not good.

    I have yet to see any UV lamp with warnings about its radiation,
    (actinic or otherwise) which does NOT produce this burning smell on my
    palm. With blacklights, this phenomenon is marginal.
  3. Thanks!
