Christopher Portier PhD, a retired U.S. government scientist who served as Director of the United States National Center for Environmental Health at the Centers for Disease Control and Prevention (CDC) and the Director of the Agency for Toxic Substances and Disease Registry, submitted a comprehensive 176 page report of the scientific research in a major brain cancer/cell phone lawsuit. Portier's report states that "the evidence on an association between cellular phone use and the risk of glioma in adults is quite strong."
"In my opinion, RF (radiofrequency) exposure probably causes gliomas and neuromas and, given the human, animal, and experimental evidence, I assert that, to a reasonable degree of scientific certainty, the probability that RF exposure causes gliomas and neuromas is high," Portier wrote.
As expected, the 46 telecom defendants in the case, which includes Motorola, Nokia, AT&T, Bell Atlantic, Cellular One, Cingular Wireless, Verizon and Vodafone, are calling to remove Dr. Portier's report and testimony from the case.
Portier represented the CDC at the World Health Organization International Agency for Research on Cancer (WHO/IARC) review of the carcinogenicity of wireless radiofrequency radiation (RFR) in 2011 where RFR was deemed a "possible carcinogen." Subsequently, Portier attempted to update the CDC website page on cell phone radiation to reflect this classification.
However, as EHT's FOIA investigations found, the CDC webpage was redrafted numerous times to include the 2011 classification and finally posted in a watered down wording three years later. Then in 2016, the CDC flip-flopped on recommending people take "caution" with cell phone radiation and removed advice about children. As of 2021, the WHO/IARC advisory committee recommends re-evaluating wireless radiation "as a high priority."
You also may remember Portier as an expert witness for the plaintiff in the case of Edwin Hardeman v. Monsanto Company (now Bayer). A unanimous 2019 verdict resulted in an award of $80 million for Mr. Hardeman.
The Murray et al. v Motorola. case is set for court hearings this summer.
