  "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.",
