The Japanese group running a partial repeat of the NTP RF cancer study has not observed genotoxic effects among male rats exposed to 900 MHz CDMA radiation at 4 W/Kg, according to a paper to be presented tomorrow at the annual meeting of the Society of Toxicology in Salt Lake City, UT (SOT2024).

The analysis of the cancer data is ongoing and will not be reported.

“A Study on Effects of Cell Phone Tower–Emitted Non-Ionizing Radiations in an Allium cepa Test System,” Environmental Monitoring Assessment, February 13, 2024. Onion roots exposed to ~1-13 µW/cm² RF from cell towers showed “enhancement of oxidative stress and genotoxicity.” The higher the exposure, the greater the effect. Levels are orders of magnitude lower than most exposure limits. From Guru Nanak Dev University, Amritsar, India.

Unremarkable science can sometimes tell a remarkable story. Two papers that were published in the last few weeks —and passed mostly unnoticed— have important, though very different, backstories.

One offers a surprising glimpse of change in the usually static field of RF research, while the other shows how much has stayed the same over the last many years.

Yet, in the end, they offer the same well-worn message, always worth repeating: Those who sign the checks, run the show.

The two papers come 30 years after Henry Lai and N.P. Singh began an experiment at the University of Washington in Seattle that would set off alarm bells across the still-young cell phone industry —and the U.S. military. Lai and Singh would show that a single, two-hour exposure to low-level microwave radiation (today, we’d say RF) could lead to breaks in the helical strands of DNA in the brains of live rats.

“WiFi Related RF EMFs Promote Transposable Element Dysregulation and Genomic Instability in Drosophila melanogaster,Cells, December 13, 2022. Experiments with fruit flies exposed to 2.4 GHz WiFi radiation at an SAR of only 0.06 W/Kg point to non-thermal genotoxic effects. Implications for genomic stability, neurodegeneration and tumorigenesis unresolved. From Italy. Open access.

“Genotoxic Effects of Exposure to RF-EMF in HL-60 Cells Are Not Reproducible,” Mutation Research/Genetic Toxicology and Environmental Mutagenesis, posted online June 28, 2013, by a German team including Günter Speit and Rudolf Tauber.

“In conclusion, two independent attempts failed to reproduce genotoxic effects of RF-EMF in HL-60 cells as reported by the REFLEX project. These repeat experiments were performed under the same experimental conditions as the original experiments and one part of the repeat study was performed by the scientists who also generated the REFLEX data.”

If you want to see just how misguided the ICNIRP enterprise really is, take a look at its new EMF exposure guidelines in the December issue of Health Physics. [See also our November 10 post.]

Start at the end with the footnote that discloses the composition of its five-member ELF Task Group (p....

The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has released two new reviews on RF radiation: (1) Exposure to High-Frequency Electromagnetic Fields, Biological Effects and Health Consequences (100 kHz-300 GHz), and (2) Epidemiologic Evidence on Mobile Phones and Tumor Risk: A Review."

The first is a 372-page review that addresses all aspects of RF interactions, from dosimetry to in vitro and in vivo experiments to epidemiological studies. It was prepared by the full commission and its advisory committees. The full text of the report is available at no charge from the ICNIRP Web site. Here is the conclusion on the plausibility of non-thermal effects:
