A survey was conducted for radiofrequency/microwave (RF/MW) nonionizing radiation and X-ray ionizing radiation at WCMH-TV (SIC- 4833) in Columbus, Ohio, on February 17, 1982. The survey was requested by a representative of International Brotherhood of Electrical Workers Local No. 71 on behalf of the company and the union. A site visit was conducted on January 6, 1982 when a list of deceased employees was obtained. Causes of death were verified. Of 20 former employees who died, four had cancer; one current employee had cancer. OSHA standards specify a maximum power density of 10 milliwatts per square centimeter for RF/MW radiation and for ionizing radiation, 2.5 milliroentgens per hour. No ionizing radiation could be detected from TV monitors. Antennas for 2 way radios exceeded the OSHA standard of 0.25 amps squared per square meter, but were nondetectable 4 to 6 inches away. The authors conclude that workers are not exposed to RF/MW or X-ray radiation hazards, and there is no evidence to support workplace exposure as an etiologic agent in the cancer deaths of employees.
