Do green light flourecent tubes in photocopying machines emit U.V. radiation ?

The majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.
If a CFL were to exceed allowable levels of UV (according to IESNA RP 27.3), its packaging would be required to be labeled with a caution label. This standard, which was developed with the assistance of the FDA, requires lamp manufacturers to provide a suitable caution if one is needed. At typical use distances, UV levels from CFLs fall below the level of general concern for normal, healthy individuals and therefore carry no such warning.
