Abstract
A chemical actinometer for determining the absolute level of exposure to ultraviolet light of a fluid to be treated for disinfection purposes. The actinometer includes a translucent sample cell through which the chemical actinometric fluid flows. The area of exposure of the actinometric fluid is controlled by allowing the ultraviolet light to pass through only a portion of the sample cell. A suitable actinometric fluid is a combination of iodide and iodate in a solution. The sample cell is positioned within an ultraviolet disinfection reactor at a position to receive ultraviolet light from the ultraviolet light source.
