Actinometry was not used because it is time consuming and expensive when compared to radiometry.
A device based on chemical actinometry, however, can be used to measure fluence rate.
A horizontal measurement grid, which is shown in Figure 1, was defined for the purpose of horizontally positioning the UV sensors and the hollow quartz spheres used for chemical actinometry in the space containing the direct UV rays emitted by the fixtures.
Iodide/iodate chemical actinometry was used to measure fluence while all of the UV fixtures used for a specific fixture configuration were turned on.
Because chemical actinometry takes considerably more time than measurements using a flat or cylindrical sensor, particularly for low fluence rates, fewer than six horizontal planes were evaluated for each fixture configuration.
