Skin contamination survey at a coal gasifier using a luminescence detector
Skin contamination of workers in synfuel industries may be directly detected using induced fluorescence. The method uses a luminoscope, a portable luminescence detector based upon a fiberoptics lightguide. The lightguide transmits long-wavelength ultraviolet excitation radiation to the skin area being monitored at an intensity 1/100th of the radiant flux of sunlight and conveys the induced fluorescence emission from the contaminant to the detector. The instrument is suitable for detecting trace amounts of various coal tars at the ..mu..g/cm/sup 2/ levels. Coal distillate and recycle solvents from liquefaction processes can be detected at a few nl/cm/sup 2/ levels. The results of a recent field test at a coal conversion facility are reported.
