Fluorescent and halogen lamps may emit small amounts UVR. However, research has shown that most do not pose a risk especially if they are fitted with a diffuser or filter that absorbs the UVR. Long-term exposure to unprotected fluorescent or halogen lamps used at close distances may increase UVR exposure.

Tungsten halogen lamps with incorporated reflectors are used extensively in area, display and home lighting. These lamps emit some UVR, which may be a hazard to the skin and eyes of people who remain in close proximity for long periods. In lighting applications where the lamps are close to people they should be fitted with a glass cover to block the UVR emissions.

UVR sources are used in a range of industrial and medical applications including phototherapy, lithography, materials testing, sterilisation and welding. High levels of UV radiation may be emitted by some sources and adequate protective measures must be taken to prevent exposure of the equipment operators. This may include shielding the sources and providing protective clothing for the operators.

Arc welders produce significant levels of UVR and the maximum recommended exposure limits for unprotected skin and eyes could be exceeded in just a few seconds or minutes. When working with arc welders, face shields or welding helmets that meet the appropriate standard and absorb UVR should always be worn. Unprotected skin should be covered with clothing and gloves that block all UV radiation.

There is also a possibility of retinal damage from the intense visible radiation emitted during welding. The welding helmet should have a dark tint which meets the appropriate standard to reduce eye exposure to visible radiation.
