Safety Tips for Using UV Lamps - Berkeley Lab

Safety Tips for Using UV Lamps Types of UV Lamps ultraviolet (UV) radiation occupies the portion of electromagnetic spectrum from 100 to 400 nanometers (nm). The UV spectrum consists of three regions: UV-A (315 400 nm) UV-B (280 315 nm) UV-C (100 280 nm) For most people, the main source of UV exposure is the sun. Exposure from the sun is typically limited to the UV-A region, since the earth s atmosphere protects us from the more harmful UV-C and UV-B regions. Only artificial light sources emit radiant energy within the UV-C band. UV generating devices may contain one or a combination of a couple or more artificial light sources (UV Lamps ) in order to achieve the desired light quality. Below are listed some of the most used types of UV generating Lamps .

UV lamps produce light radiation from ultraviolet through visible to infrared radiation. The biggest hazard comes from the UVR. UVR cannot be seen and is not felt immediately, but it is harmful to both the eyes and skin. The user may not realize the danger until after the exposure has caused damage. Symptoms can occur 4 to 24 hours after exposure.
