ACCURACY AND REPRODUCIBILITY OF CALIBRATIONS ON THE SKIN USING THE FIVES FLUORESCENCE MONITOR

摘要

Dermal contamination from products such as pesticide formulations may be measured by adding a fluorescent dye as a tracer, and photographing the glow of the dye on the skin under ultraviolet light. The Fluorescence Interactive Video Exposure System (FIVES) fluorescence monitor, developed at the Health and Safety Laboratory, uses calibrations of intensity of glow against surface concentration of dye which are affected by the natural fluorescence of the skin and by skin hue. Calibrations of two dye/product mixtures upon the skin of several volunteers showed that a simple multiplicative correction procedure aligned all the responses to one calibration curve for each mixture.
