ULTRAVIOLET
RADIATION
The
ultraviolet (UV) region of the electromagnetic spectrum is intermediate
in wavelength and frequency between the x-ray and the visible
regions. UV radiation can produce damage to the eyes and
skin. The type and extent of the damage is determined
by the wavelength of the radiation, and the length of the exposure.
UV radiation is emitted when excited atoms make transitions
from a higher to a lower energy state, thus releasing photons
with energies in the UV range. The primary man-made method
of generating UV radiation is to excite atoms via an electrical
arc through a gas or a vapor and intense heat. Examples
of sources of UV radiation are mercury vapor lamps, fluorescent
lights, germicidal lamps, black light lamps, plasma torches,
open arcs (such as those used in arc welding) and sunlamps used
in the tanning salon industry.
The only source
of UV radiation currently regulated by the Department is mercury
vapor lamps, see N.J.A.C. 7:28-41.
At this time, neither the Department of Environmental
Protection nor the Department of Health regulate tanning salons.
Any questions regarding these should be referred to local
health department officials.
