Therefore, 99.9999038793% of the energy emitted is at wavelengths shorter than 1E-4m (0.1mm).
Or, across the entire continuous spectrum (0, 1e-4m], the total energy from the Sun is 0.0009612W, or 961uW.
You might complain that 961 uW is much more than 10nW, but again, you have to consider that 961 uW is across the entire spectrum (0,1E-4]. The Sun is less powerful at narrow spectrums because otherwise it'd drown out the cell phone tower (Or rather we pump power into the antenna to overcome the "noise" from the Sun).
I'd reproduce the numbers, but unfortunately my HP48 underflows at such narrow bandwidths.
And the "LED" at your face is, of course, much more powerful than the Sun since (as you pointed out) by the inverse square law, it has to pump out a lot of power to reach the tower.
Nor do I happen to think LEDs are harmless. Using LEDs to affect biological system is a very rich area of study.
Do I think non-ionizing radiation is harmful? I doubt it. But comparing a 1000W/m^2 @ 5400K black body radiator to a cell phone tower is dishonest.
5G gets the techno-utopians in HN all excited about the possibilities of [INSERT THE POINT OF 5G] and they'll get mad at anything that threatens its introduction.
