The difference between us is
that you think that questions of effects of such stimulation--over long intervals--is 'settled science' proving a negative. Already.
What is established, thus far--is an absence of any correlations with brain-or-other 'cancers'.
'Non -ionizing' is a bit too digital in the concept: energy levels at ear may not 'strip' electrons from the say, outer/valence (pseudo-'layer')--the textbook definition. But any energy source, now applied for the first time to billions of the species, on a regular schedule:
is New to the organism (us) in any Darwinian sense. Messing slightly with the ongoing overall energy levels of bio-complex materials is a topic few have thrown any $$ at studying, to my knowledge. Reaction rates (for just one) Are affected by any elevated 'temperature'--which is what that-all reduces to, when it's random==like heat.
[I presume you're not lumping together the Σ-μwatts/cm2 of the fantastic soup of all the radiation in the ether/air--as from all the towers. That always bears long-term, reliable attention, but my concern is solely with the transmitter on the ear, here.]
No, I anticipate-Not some epidemic of cel-fone created Zombies arising to trump the best/worst sci-fi potboilers: I do recall What-exactly caused Thalidomide's effects on pregnant women/Missed by all, until the damage happened.
One of the chemicals used in synthesizing that drug, had both dextro- / laevo-rotary forms; the culprit was the Fact that, in production the Wrong/Untested form of this substance was used. Etc.)
And yes, we have plenty-else to try to parse, re exploding techno, running well-beyond our financial willingness to follow-effects post-production. Unless people are dropping like flies.
(And the certainty that profit / also not being successfully-sued: are the major concerns of all Corporations. Not subtleties of any sort.)
Oh/and: new phones are Different: they are thinner; delivered 'heating' goes as inverse-cube from antenna-->ear. (Hell, the thickness/prominence of the ear may prove to be enough attenuation that.. any anomalies will appear there, rather than through a thick skull. May..)
What, me worry?
