Modern wireless technology, including cell phones, cordless phones, Bluetooth devices, Wi-Fi networks, smart utility meters, and radio and TV transmission, rely on radio frequency (RF) fields to communicate. Medical scanners, radar systems and microwave ovens also use radio frequency fields. RF broadly refers to electromagnetic waves oscillating between one hundred thousand times per second (100 kHz) to three hundred billion times per second (300 gigahertz). Cell phones transmit and receive signals in the range 600 megahertz (MHz) to 3 GHz. The intensity of electromagnetic radiation can be expressed as microwatts per square-centimeter (µW/cm2) which refers...

Written By: Ryan McCaughey, PhD. Scientists have found that cell phone radiation exposure has a negative effect on memory performance in adolescents. A study of over 600 12 to 17 year olds at the Swiss Tropical and Public Health Institute (Swiss TPH) found cumulative cell phone RF exposure over one year may have a negative effect on the development of figural memory performance.[i] Figural memory, which is the ability to recall abstract shapes, is mainly located in the right brain hemisphere and association with RF was more pronounced in adolescents using the phone on the right side of the head....

Written By: Ryan McCaughey, PhD The Supreme Court has sent the CTIA v. Berkeley case ack to the Ninth Circuit Court of Appeals for reconsideration. The Berkeley "Right to Know" Ordinance requires that cellphone retailers display the following notification: “To assure safety, the Federal Government requires that cellphones meet radiofrequency (RF) exposure guidelines. If you carry or use your phone in a pants or shirt pocket or tucked into a bra when the phone is on and connected to a wireless network, you may exceed the federal guidelines for exposure to RF radiation. Refer to the instructions in your phone...

Written By: Ryan McCaughey, PhD  A study from the UK has found that the incidence of Glioblastoma Multiforme (a malignant brain tumor) more than doubled between 1995 and 2015.[i] Gliomas are tumors associated with glial cells (cells that support and protect neurons in the brain). They classified by cell type, by grade, and by location. Glioblastoma Multiforme (GBM) are an aggressive malignant form of the most common glioma (astrocytoma). Critics of the study argue that the observed increase could be due to better diagnostic imaging such as MRI and a change in how the WHO classifies gliomas during the analyzed...

Written By: Ryan McCaughey, PhD In March 2018 an expert panel of scientists convened to review the data from the National Toxicology Program (NTP) Technical Reports on Cell Phone Radiofrequency Radiation. The research assessed the health effects from exposure to radiofrequency radiation in rats and mice.[i] The peer review panel concluded that the report showed “clear evidence” that exposure to cellphone radiofrequency (RF) radiation resulted in tumors in tissues surrounding nerves in the hearts of male rats. The study also found “some evidence” that it caused tumors in the brains and adrenal glands of male rats. There was also “equivocal”...

Written By: Ryan McCaughey, PhD In 2011 the World Health Organization (WHO) International Agency for Research on Cancer (IARC) classified radiofrequency electromagnetic fields as possibly carcinogenic to humans, based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.[i] The conclusion of the IARC expert panel of 31 scientists was based partly on the results of the INTERPHONE study – a $24million, 13 country case-control study of the risks related to mobile phone use. The study found those who used a cell phone for more than 10 years were twice as likely to develop glioma.[ii]...
