In a 10/23/98 message, Dr. Eng. Sergio Cavalerri asks for information on
ozone emissions from UV lamps used in the printing industry. Dr. Cavallari
should not worry.

The amount of ozone generated by such lamps is exceedingly small . These
lamps give a steady state concentration, while running, of less than 0.02
parts/million. This is about 1/5 of the 0.1 ppm allowed for continuous
exposure to ambient ozone as specified by the American Conference of
Government Hygenists. At this level, the ozone is barely detectable by a very
sensitive human nose.
