Abstract

Improving the Quality of Radiofrequency Bioeffects Research: The Need for a Carrot and a Stick Vijayalaxmi, Kenneth R Foster. Improving the Quality of Radiofrequency Bioeffects Research: The Need for a Carrot and a Stick. Radiat Res. 2021 Jul 16. doi: 10.1667/RADE-21-00079.1. Abstract This commentary considers research needs for radiofrequency (RF) energy above 6 GHz, including in the "high band" of 5G New Radio (NR) communications systems that exists just beneath the mm-wave band (30-300 GHz). As of late 2020, approximately 100 RF bioeffects studies have been published involving exposures above 6 GHz, encompassing a wide range of exposure levels and frequencies. A majority of these studies report statistically significant effects of exposure, many at exposures within international safety limits. This commentary examines 31 genetic damage studies involving RF exposures above 6 GHz in the context of two sets of quality-assessment criteria: 1. "Risk of bias" (RoB) criteria used for systematic reviews of health-related studies; and 2. a broader set of criteria for research quality from a different scholarly approach (metascience). The 31 studies report several statistically significant effects of exposure on different markers for genetic damage. These effects, if real, would have great potential significance for carcinogen risk assessment. However, the studies as a group have significant technical weaknesses, including small size, failure to meet multiple RoB criteria, naïve use of statistics, and lack of prespecified hypotheses and methods of analysis, all of which increase the chances of false discovery. Here we propose a "carrot" (adequate funding to support high-quality research) and a "stick" (more stringent review of bioeffects manuscripts, including explicit instructions to reviewers to assess study quality) approach to increase the reliability of RF bioeffects studies to facilitate health agency reviews of this socially controversial topic. pubmed.ncbi.nlm.nih.gov

Main findings

This commentary discusses research needs for RF exposures above 6 GHz (including the high band of 5G NR) and reviews 31 genetic damage studies using risk-of-bias and broader research-quality criteria. While the studies report several statistically significant effects on genetic damage markers (including at exposures within international safety limits), the authors state the body of evidence has substantial technical weaknesses (e.g., small size, failure to meet multiple RoB criteria, naïve statistics, lack of prespecified hypotheses/analysis), increasing the likelihood of false discoveries.

Outcomes measured

genetic damage markers
study quality/risk of bias
false discovery risk

Limitations

Commentary rather than a primary experimental study
Assessment limited to what is described for 31 genetic damage studies above 6 GHz; specific exposure parameters and quantitative results not provided in the abstract
Conclusions emphasize methodological weaknesses; does not establish whether reported effects are real
