Introduction
most fluorescent lights are 11- or 12-watt bulbs
Adverse effects
- fluorescent lights generate ultraviolet (UV) radiation from electrical discharge into mercury vapors
- energy in the UV range is converted to visible light by a phosphor that coats the inside of a glass envelope
- double-envelope bulbs emit almost no UV radiation
- some single-envelope bulbs emitted UVC & UVB, probably because of defects in the phosphor coating
- about 55% of the single-envelope bulbs emitted enough UV radiation in less than 30 minutes to exceed the exposure limit values recommended by the International Commission on Non-Ionizing Radiation Protection
