UV Irradiance is the radiant power, within a stated wavelength range, arriving at a surface per. unit area, usually expressed in watts or milliwatts per square centimeter. Irradiance varies with lamp. output power, efficiency and focus of its reflector system, and distance to the surface.
Arc welders must wear eye protection and cover their skin to prevent photokeratitis and serious sunburn. Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm (30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight.
