A Review of Selected Biological Effects and Dosimetric Data Useful for Development of Radiofrequency Safety Standards for Human Exposure

R.A. Tell, F. Harlen · 1979

The authors reviewed selected biological effects and dosimetric data to develop radiofrequency safety standards based on thermogenic properties of electromagnetic fields. The 10 mW/cm² limit appears adequate for frequencies above 1 GHz but may be too high for lower frequencies due to body resonances causing increased energy deposition and local temperature rises. They noted that energy absorption in small laboratory animals can be up to 30 times greater than in humans at the same field strength. The current averaging period of 0.1 hours is considered unjustifiably short.

Radiofrequency Radiation Alters the Immune System: Modulation of T- and B-lymphocyte Levels and Cell-Mediated Immunocompetence by Hyperthermic Radiation

Robert P. Liburdy · 1979

Researchers exposed mice to whole-body radiofrequency radiation at 26 MHz that raised core temperature by 2°C over 15 minutes, inducing transient lymphopenia and increasing splenic T- and B-lymphocytes. Repeated RFR exposures sustained lymphopenia and further elevated splenic T- and B-lymphocyte levels. Chronic RFR exposure decreased thymic weight, thymic and splenic cell density, and suppressed delayed-type hypersensitivity. Warm air exposure increased only splenic B-lymphocytes and did not change delayed hypersensitivity, while RFR exposure raised plasma corticoid levels severalfold. A synthetic glucocorticoid reproduced the lymphopenia, splenic T- and B-lymphocyte increases, and thymic involution observed with RFR.

INDUSTRIAL HYGIENE WALK-THROUGH SURVEY REPORT ON RF RADIATION EXPOSURES FROM HEAT SEALERS

Clinton Cox, Betsy Egan, Bill Murray, Bob Herrick · 1979

On November 29, 1978, NIOSH conducted a walk-through survey of the RF sealing area at Standard Plastic Products in South Plainfield, New Jersey. The purpose was to identify workers for a study on health effects from occupational radio frequency radiation exposure. Electric and magnetic fields from the heat sealers were measured and corrected for duty cycle. All three sealers produced electric fields greater than 1000 V/M, exceeding the ANSI guideline of 200 V/M by at least five times. A cohort of 15 workers, mostly elderly women, was identified and could be used in a study if combined with similar cohorts from other plants.
