‘...an association has been established between the use of cellular telephones and the risk of gliomas...’
Christopher J. Portier, Ph.D., former director of the National Center for Environmental Health at the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR), and a scientific advisor for the World Health Organization (WHO), recently completed an expert report on brain tumor risk from exposure to radio frequency (RF) radiation used in cellphone technology.
After completing a comprehensive review of the scientific literature, Dr. Portier concluded:
"In my opinion, RF 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."
