Written By: Ryan McCaughey, PhD. Exposure to cellphone radiofrequency (RF) radiation resulted in tumors in tissues surrounding nerves in the hearts of male rats, according to studies from the NIH National Toxicology Program (NTP). On February 2nd 2018, the NTP released draft technical reports from its 10-year, $25 million toxicological studies assessing the health effects from exposure to radiofrequency radiation in rats and mice.[i] The NTP will hold an external expert review of its complete findings from these rodent studies March 26-28. The studies show an increase in the incidence of malignant schwannomas in the hearts of male rats as...

Just as we predicted in our November 2017 blog post, the CTIA has petitioned the U.S. Supreme Court to block the city of Berkeley’s cellphone “right to know” ordinance. The law 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...

Do You Need a Digital Detox? By: Cassie Horton   With the new year on the horizon, we’re busy reflecting on the past year and thinking of resolutions for the upcoming year. Most New Year’s resolutions are focused around being healthier, whether it’s exercising more, eating better, detoxing, or focusing on personal wellbeing. But have you heard of a digital detox and the health benefits behind this new trending topic?   A digital detox involves taking a break from using electronic devices such as smartphones or computers, with the goal of reducing stress or focusing on social interaction in the...

reach cases are designed and tested by our team of antenna engineers in a state-of-the-art lab in Carlsbad, California. Phone and reach case antenna performance are very accurately measured with an ETS-Lindgren AMS 7000 reverberation chamber.1 The phone’s frequency, bandwidth and other signal variables are controlled with an Anritsu MT8820C Radio Communication Analyzer2 – it’s like having our own personal network and cell tower. Similar to cell phone manufacturers and networks, we measure active OTA (Over-The-Air) metrics: TRP and TIS. TRP (Total Radiated Power) is the maximum power the phone can transmit and TIS (Total Isotropic Sensitivity) is a measure...

Written by: Ryan McCaughey, PhD. On December 13th 2017, CDPH (California Department of Public Health) issued guidelines on how to minimize your exposure to cell phone radiation.1 The document describes RF energy, lists some of the potential health concerns, and provides guidance on how people can reduce their exposure. These guidelines include: Keeping the phone away from the body Reducing cell phone use when the signal is weak Reducing the use of cell phones to stream audio or video, or to download or upload large files Keeping the phone away from the bed at night Removing headsets when not on...

alara cases are designed and tested by our team of antenna engineers in a state-of-the-art lab in Carlsbad, California. We measure cell phone radiation exposure in accordance with international standards using the SAR metric. SAR stands for Specific Absorption Rate and it quantifies the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. In the US, SAR measurement protocols are regulated by the FCC. Measurements are made inside a SAM (Specific Anthropomorphic Mannequin) phantom head which mimics the size, shape and RF properties of a human head. The SPEAG cSAR...
