<p>A chemical actinometer (10) for determining the absolute level of exposure to ultraviolet light of a fluid to be treated for disinfiction purposes. The actinometer (10) includes a translucent sample cell (15) 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 (15). A suitable actinometric fluid is a combination of iodide and iodate in a solution. The sample cell (15) is positioned within an ultraviolet disinfection reactor (12) at a position to receive ultraviolet light from the ultraviolet light source (30).</p> |
