Abstract

We propose a biologically based measure of EMF radiation to replace the energy-based "specific absorption rate" (SAR). A wide range of EMF frequencies has been linked to an increased risk of cancer. The SAR value used to measure the EMF dose and set the safety standard in the radiofrequency (RF) range fails as a standard for predicting cancer risk in the ELF power frequency range. Because cancers are believed to arise from mutations in DNA, changes in DNA induced by interaction with EMF could be a better measure of the biologically effective dose in both frequency ranges. The changes can be measured by transcriptional alterations and/or translational changes in specific proteins. Because ionizing radiation also causes DNA damage, a biologically based standard related to stimulation of DNA could apply over a much wider range of the electromagnetic spectrum. A safety standard for exposure to a wide range of non ionizing frequencies can be based on the documented changes in DNA biochemistry that arise from interactions with EMF.

Main findings

The article proposes replacing energy-based SAR with a biologically based EMF dose metric grounded in documented EMF-associated changes in DNA biochemistry (e.g., transcriptional and/or translational changes). It argues SAR is inadequate for predicting cancer risk in the ELF power-frequency range and suggests DNA-based measures could apply across a wider range of non-ionizing frequencies.

Outcomes measured

DNA changes (mutations/biochemical changes)
Transcriptional alterations
Translational changes in specific proteins
Cancer risk (as discussed)
Dosimetry/safety standard (SAR vs biologically based measure)

Limitations

Appears to be a proposal/review without primary experimental data described in the abstract.
No specific frequencies, exposure levels, durations, or study populations are provided in the abstract.
Claims about links to cancer risk are not quantified in the abstract.
