The risk assessment for all cell phone use was done by electrical engineers, not medical types.
“The risk assessment for all cell phone use was done by electrical engineers, not medical types.”
Very misleading. Risk assessments for electronic devices transmitting energy are done in house first. But they do them to standards.
The standards are devised by various high powered working teams (”ad hoc”) with top-of-their-field expertise in the subject matter. These teams consist of Doctors (many kinds), engineers, Phds (physicists, EEs, Antenna, etc.), EEE reps,sometimes lawyers (ugh), and then drafts released for review by the entire community with interest and expertise.
After several rounds of reviews, meetings, updates, they bring in government bodies to informally get them in the loop. More feedback, meetings, revisions. Then they release “The Final Recommendations of XXXX by the YYYY Team...” and hope the appropriate governing agency (NIST, ANSI, OSHA, EU, FDA, etc) will give their blessing, or at least do nothing.
These standards then get voted on and released by the appropriate governing body. (Until then, “The Final Recommendations...” get used)
THEN the engineers at a company develop and test their devices to those standards.
How do I know this? Military RF tech (1200 hrs initial classroom training), then AS and EE degree, then development of medical devices for over 25 years. Including working with the ad hoc comitte that set the maximum radiation doses allowed from MRI machines, while working with some of the inventors of MRI at Hopkins. The radiation standards and physics are similar to cell phones, only a lot higher doses! But shorter times. I’ve worked on several other radiation emitting medical devices as well.
Hint: All use SAR (Specific Absorption Rate) as the standard method for predicting and testing safety in the human body.
Everything emitting EM radiation below ionizing (which is all the way up the band, beyond microwave, beyond gigahertz, near the top of Terahertz, beyond infrared, to UV light, btw—cancer, ring a bell?) is lab tested against SAR limits. The results of which determine whether your device gets regulatory approval. All radiation emitting devices must pass the approval body, then they permanently put the appropriate stamp on the device. (UL, CE...)
Although I was an informal guinea pig sometimes in the MRI machine to see if certain settings would hurt. Sometimes they did.
Anyone interested just look up SAR and cellphones to learn. Start there.
