Optical radiation, especially in the ultraviolet region, is potentially hazardous to skin and eyes. Gigahertz-Optik GmbH produces optical radiation measuring devices to determine the UV radiation (skin and eye), blue light (eye) and infrared (skin) hazards in accordance with international standards. Some typical application examples of Gigahertz-Optik GmbH products are listed in this chapter.
Personal dosimetry of UV erythema effective radiation exposure
The assessment of erythema-effective radiation exposure is usually based on data recorded by stationary measuring devices, but this does not replicate the actual exposure experienced in most real situations. The measurement of UV irradiation experienced by outdoor workers, for example, requires personal dosimeters – see references –. Outdoor sports players may also be subjected to relatively high doses of UV .
Measurement and evaluation of UV radiation during arc welding
The use of personal protection equipment (PPE) is essential during welding processes due to the high levels of UV radiation produced. Evaluating the hazard associated with UV exposure during welding processes, requires the spectral irradiance to be measured and weighted in terms of biological effectiveness. The measurement of the dynamic optical processes within welding arcs requires specialist equipment as well as expertise in its use and evaluation of the measurement results.
