- “Association Between Maternal Exposure to Magnetic Field NIR During Pregnancy and Risk of Attention-Deficit/Hyperactivity Disorder in Offspring in a Longitudinal Birth Cohort,” JAMA Network Open, March 24, 2020. “Consistent with the emerging literature, this study suggests that in utero exposure to high levels of MF non-onizing radiation was associated with an increased risk of ADHD, especially ADHD with immune-related comorbidity.” The most recent study by De-Kun Li of Kaiser Permanente. Note: “high” is defined as a 24-hour exposure of ≥1.5 mG (90th percentile). According to a 1998 survey, >40% of Americans are exposed to >1 mG. And the ICNIRP 2010 guidelines allow the general public to be exposed up to 2,000 mG.
- Review of Published Literature between 2008 and 2018 of Relevance to Radiofrequency Radiation and Cancer, U.S. FDA, released February 10, 2020. “[T]here is insufficient evidence to support a causal association between RFR exposure and tumorigenesis. There is a lack of clear dose-response relationship, a lack of consistent findings or specificity and a lack of biological mechanistic plausibility.”
- “RF-Induced Temperature Increase in a Stratified Model of the Skin for Plane-Wave Exposure at 6-100 GHz,” Radiation Protection Dosimetry, posted January 16, 2020. “The maximum observed temperature increase is 0.4°C for exposure at the present power density limit for the general population of 10 W/m² [1 mW/cm²]. This result is more than twice as high as the findings reported in a previous study.” From IT’IS in Zurich.
- “Comparative Cyto- and Genotoxicity of 900 MHz and 1800 MHz EMF Radiations in Root Meristems Allium cepa,” Exotoxicology and Environmental Safety, January 2020. Very low SARs lead to DNA breaks: 0.09 W/Kg @900 MHz and 0.169 W/Kg @1.8 GHz. Damage “more pronounced” at 1800 MHz. (Allium cepa = onion)
- “Whole-Body Exposures to RF-EMF Energy Can Cause DNA Damage in Mouse Spermatozoa via an Oxidative Mechanism,” Scientific Reports, November 25, 2019. In summary, our evidence supports the hypothesis that sustained whole-body RF-EME is capable of inducing a state of oxidative stress in the male germ line, a cell vulnerable to the effects of ROS. … Furthermore, our data further implicate the mitochondria as the target for RF-EME biophysical interaction, with a consequential elevation of mitochondrial ROS generation being linked to reduced motility and elevated oxidative DNA damage and DNA fragmentation in the spermatozoa of exposed male.” From Australia. Open access.
- “Changes in Trends in Thyroid Cancer Incidence in the United States, 1992 to 2016,” Journal of the American Medical Association, December 24-31, 2019. “Between 2009 and 2016, after 3 decades of rapid increase, the incidence of thyroid cancer incidence in the United States reached a plateau and possibly started to decline.”
- “If Jet Radars Don’t Raise Cancer Risk, Why Did the Navy Coat Some Cockpits in Gold?” McClatchy News, November 27, 2019. An investigation has found a cluster of cancer cases among U.S. Navy pilots of E-2 Hawkeye early warning aircraft exposed to radar radiation.
- “Evaluation of the Genotoxicity of Cell Phone RFR in Male and Female Rats and Mice following Subchronic Exposure,” Environmental and Molecular Mutagenesis, posted October 21, 2019. From the NTP: "[S]ignificant increases in the levels of DNA damage measured by the comet assay were seen in several tissues from rats and mice, indicating that RFR may be capable of causing increases in DNA damage.” More here and here.
- “Parental Occupational Exposure to Low-Frequency Magnetic Fields and Risk of Leukaemia in the Offspring,” Occupational & Environmental Medicine, July 29, 2019. “We did not find any associations.” Pooled analysis of 11 case-control studies by the Childhood Leukaemia International Consortium, including Joachim Schüz of IARC and Elisabeth Cardis. Open access.
- “Untargeted Metabolomics Unveil Alterations of Biomembranes Permeability in Human HaCaT Keratinocytes upon 60 GHz Millimeter Wave Exposure,” Scientific Reports, June 27, 2019. Millimeter waves “might alter the permeability of cell membranes.” An “unexpected” finding. Open access.
