Abstract
A walk through survey was made at the Blair Industries (SIC-3079), located in Chicago, Illinois for the purpose of identifying a population of workers which could be used in a study to determine whether any health effects are associated with occupational exposures to radio frequency (RF) radiation. Blair, a manufacturer of mechanical parts for the electronics industry, began heat sealing operations in 1971. The company also manufactured a wide variety of vinyl products such as page binders, plastic zipper pouches, page protectors and other items. The company employed about 300 people. Up to 35 to 40 persons worked in the RF heat sealing area, most of them females. Female employees who become pregnant, frequently work right up to the time of birth and often return to work as soon as possible. There were 28 heat sealers located in this area. Of the five heat sealing presses evaluated, current guidelines for electric and magnetic field exposures were equalled or exceeded at two of the presses. While a proven hazard has not been documented at the levels measured, a resonant absorption effect has been demonstrated which indicates that maximal heating of the body will occur at these frequencies. The authors recommend that, in the best interests of the employees, shielding should be installed. Blair Industries was being considered as a possible participant in a larger study of exposures to RF radiation.
