[Bioeffects of chronic exposure to radiofrequency electromagnetic fields of low intensity (standardization strategy)].

Abstract

A retrospective analysis of the experimental researches on the effect of radio frequency electromagnetic fields (EMF) on human health, carried out in the USSR, is presented. The results of chronic exposure of laboratory animals to EMF have been considered. Apparently, EMF in the range of 1750-2750 MHz with power density up to 100-500 W/cm2 caused in immune globullin fractions, and a development of autoimmune processes. The changes in parameters of reproductive functions and posterity, the increase in embryo mortality were found. The standartization strategy used in the USSR and currently applied in Russia has been discussed.

Main findings

This retrospective analysis summarizes USSR experimental research on radiofrequency EMF and considers chronic laboratory animal exposures. It reports that RF EMF in the 1750–2750 MHz range at power density up to 100–500 W/cm2 was associated with changes in immune globulin fractions and development of autoimmune processes, as well as changes in reproductive function parameters and offspring outcomes including increased embryo mortality. The USSR/Russia standardization strategy is discussed.

Outcomes measured

• immune globulin fractions changes
• autoimmune processes
• reproductive function parameters changes
• posterity effects
• embryo mortality
• standardization strategy (USSR/Russia)

Limitations

• Retrospective review; methods and inclusion criteria not described in the abstract
• No sample sizes or quantitative effect estimates reported
• Exposure metric reported as power density; details of dosimetry and study conditions not provided
