Discussions of the nature of electromagnetic and ultraviolet radiation, the biological effects of an standards for ultraviolet radiation UV and some of the available instrumentation used to measure UV preceded the discussion of the critical evaluation made of the performance and physical characteristics of the NIOSH prototype UV Hazard Monitor UVHM dubbed the UVALERT. The evaluation lead to the development of UV hazard survey procedures and an UV Survey Worksheet. The UVHM was found to basically conform to the requirements of the NIOSH UV Criteria Document with the spectral response peaking at 270 nm with essentially no response to wavelengths above 325 nm. The UVHM was capable of detecting irradiance levels from .0000001 to .00003 Wattssq cm without the use of optical neutral density filters. Discussion of the techniques developed to determine the spectral response, the calibration factor, the angle of acceptance, and the minimum beam diameter for full UVHM response were presented.
