Ultraviolet radiation actinometer

摘要

A meter for determining the integrated effect of the exposure of human skin to the sun's ultra-violet radiation by means that provide an instrument cheap enough to use on a wide scale. The World Health Organization sees "the greatest value" in a suitable instrument. The solar radiation is passed through a UV filter to a fused silica tube containing a disulphide solution which, under the action of ultra violet (UV) radiation, displays a wavelength response similar to that of the erythemal action spectrum.
