This paper presents a design methodology for an electronic ballast applied to ultraviolet radiation (UV) lamps for a drinking water purifier, providing adjustable UV dose in order to ensure the inactivation of microorganisms' ...

The field of atmospheric ultraviolet radiation (UV) research is plagued with difficulties in nomenclature. The problems arise from (a) the strong wavelength dependence of UV radiation received at the Earth's surface, (b) ...

Ultraviolet radiation is a type of non-visible radiation in the solar spectrum, its wave length is short and has great power; measurements of UV radiation indicate us the degree of intensity with which reach the Earth´s ...
