“RFR has the potential to induce measurable DNA damage” NTP on DNA breaks

Scientists from the National Toxicology Program presented their data on the genotoxicity of cell phone radiation in rats and mice at the annual meeting of the Environmental Mutagenesis and Genomics Society held in Raleigh, North Carolina from September 9-13, 2017.
Male and female rats and mice were exposed to 2G cell phone radiation, either CDMA or GSM, for 18 hours per day in 10 minute intervals. The rats were exposed to cell phone radiation at 1.5, 3, or 6 W/kg specific absorption rate (SAR) for 19 weeks from gestation day 5. The mice were exposed to radiation at 2.5, 5, or 10 W/kg SAR for 13 weeks from postnatal day 5.
DNA damage was assessed in three brain regions, in liver cells and in blood leukocytes using the comet assay. Chromosomal damage was assessed in peripheral blood erythrocytes using the micronucleus assay.
DNA damage was significantly increased:

  • in the frontal cortex of male mice from either CDMA or GSM cell phone radiation exposure,
  • in peripheral leukocytes of female mice from CDMA exposure, and
  • in the hippocampus of male rats from CDMA exposure.

There were no significant increases in micronucleated red blood cells in rats or mice.

The authors concluded that, “exposure to RFR [radio frequency radiation] has the potential to induce measurable DNA damage under certain exposure conditions.”

The NTP is scheduled to publish a complete report about its cell phone radiation studies in early 2018. The FDA called for this research in 1999 http://www.saferemr.com/2015/11/government-failure-to-address-wireless.html

NTP: Cell Phone RF Breaks DNA Consistent with Higher Tumor Counts 20 Years After Landmark Lai-Singh Study: http://microwavenews.com/news-center/ntp-comet-assay

The NTP animal study supports the results of the REFLEX studies, which found that cell phone radiation can trigger DNA breaks in isolated human fibroblasts and thus can cause damage to their genes (DIEM et al. 2005, SCHWARZ et al. 2008). Besides these large studies, which also caused quite a stir in the media, there are now more than 50 individual in vivo and in vitro studies that demonstrate DNA breaks (HARDELL/CARLBERG 2012, RÜDIGER 2009). They are all listed at the EMF-Portal, the reference database of the WHO and the German federal government. The BioInitiative Report 2012 also includes a list (BIOINITIATIVEREPORT 2012, Chapter 11 – 14). We also refer to the Israeli studies by SADETZKI et al. (2008) and CZERNINSKI et al. (2011) that found a significantly increased tumor risk of the parotid glands, which has been reflected in a fourfold increase in the Israeli Cancer Registry (MORGAN et al. 2014).
