![]() In Sweden there are estimated to be about 50 facilitiesĮmploying the application of UV radiation curable coatings on Health effects to the skin and eyes after a short exposure. Radiation emitted from UV curing units may result in harmful UV radiation.('-3) The high intensity and the character of UV He use of ultraviolet (UV) radiation to cure wood surfaceĬoatings (multifunctional acrylate lacquers and paints) involves a significant potential risk for occupational exposure to L.A.: ASSESSMEM OF ULTRAVlOLEl h!ATlON EXFOSURE IN THE Required for workers during maintenance of unshielded equipment in Holes and fissures, and routinely checked and maintained in order toĪfford adequate protection fkom high intensity W radiation at biologically hazardous wavelengths. Units must be equipped with proper radiation shields, including the In different wavelength regions varied moderately (UV, 38 to 56% Radiation was measured below the unshielded bottom of a W curing Plants MPETs varied &om 6 seconds to 3 minutes. Direct W radiationįkom holes and fissures in the units was detected at four of the six MPETs varied between 8Īnd 126 seconds at entrance and exit openings and between 0.5 andĢ.3 hours at 0.8 m &om the W curing units. MPETs of 0.6 to 0.03 seconds, respectively. The substrate passage level ranged &om 100 to 200 mW/cm2, giving International Radiation Protection Association/Intemational NonIonizing Radiation Committee. The spectral power distribution was weighted for biological effect using Wester's approximation equations of the spectral effectiveness curve adopted fkom the Intensity of the UV radiation was measured using a radiometerĮquipped with W, and W, detectors. The spectral irradiance was measured between 250Īnd 400 nm using a calibrated diode array spectrograph, and the We have investigated the intensity and spectralĭistribution of W radiation and determined the maximum permissible exposure times (MPETs) at different fixed po ints surrounding the Information on W radiation spectra and exposure levels under these Exposure to W radiation involvesĪ potential health hazard to workers in this industry and there is little Ultraviolet (W)radiation curing of paints and lacquers has rapidly Nylander-FrenchA~C~Uĭownloaded by at 01:20 14 June 2016ĪDivision of Work Organization and Technology and BDepartrnentof Occupational Medicine, National Instituteįor Working Life, S-171 84 Solna, Sweden CCurrentaddress: Department of Environmental Sciences andĮngineering, School of Public Health, University of North Carolina at Chapel Hill, North Carolina 27599-7400 ĭTo whom correspondence should be addressed Jouni Surakka,A Torkel Fischer,U Gunnar Roskn,* and Leena A.
