Survey Report on RF Radiation Exposures from Heat Sealers at Beaverite Products, Inc., Beaver Falls, New York

摘要

The effect of radiofrequency (RF) radiation exposures from heat sealers was investigated in workers in a polyvinyl-chloride and vinyl-acetate production facility (SIC-2821). The RF radiation exposure of 16 operators at 8 heat sealers were measured. Six of eight heat sealers generated incident radiation fields in excess of the current 10 milliwatts per square centimeter OSHA standard. Thirteen of the 16 operators were exposed to incident radiation fields in excess of the current radiation standards of 200 volts per meter and 0.5 amperes per meter for electric and magnetic field intensities, respectively. The authors recommend that appropriate shielding be installed on the RF heat sealers.
