Rats exposed to combined CDMA and WCDMA signals at 2.0 W/kg each for 45 minutes daily, five days a week, for up to 8 weeks showed no detectable changes in immune parameters.

Plain English Summary

Summary written for general audiences

Researchers exposed male Sprague-Dawley rats to RF-EMF for 45 minutes per day, five days per week, for up to eight weeks. Each signal had a whole-body average SAR of 2.0 W/kg. The combined exposure did not affect the measured immune parameters.

Why This Matters

The study measured blood hematology, splenocyte subtypes, cytokine production and mRNA expression for several cytokines, as well as immunoglobulin levels in serum. Every two weeks, 20 rats were autopsied for analysis. The authors noted that the total SAR of 4.0 W/kg was higher than the ICNIRP whole-body limit of 0.4 W/kg for the general public.

Quick Questions About This Study

Rats were exposed to RF-EMF for 45 minutes per day, five days per week, for up to eight weeks. Each signal had a whole-body average SAR of 2.0 W/kg. The signals were CDMA at 849 MHz and WCDMA at 1.95 GHz applied simultaneously.
The study measured blood hematology, splenocyte subtypes, cytokine production and mRNA expression for several cytokines, as well as immunoglobulin levels in serum.
The combined exposure did not affect the measured immune parameters.
Every two weeks, 20 rats were autopsied for analysis.
The total SAR of 4.0 W/kg was higher than the ICNIRP whole-body limit of 0.4 W/kg for the general public.
