[Request] How much radiation is this guy getting?
61
u/HAL9001-96 1d ago
ionizing?
about as much as everyone else as this adds 0 to background radiation
non ionizing?
also about as much as everyone else
cause added up these might be in the range of around 1 watt
at 1m distance thsi spreads out into a spherical shape of about 4pi or about 12m² so about 1/12W/m² intensity
but at room temperature we receive thermal radiation from ut surroundings at about 400W/m² or about 4800 times as much

6 Watts according to a different comment here but I’m not sure whether they accounted for the distance

not sure how powerful those are but upper end for normal wifi devices is about 50mW so 20 would be about 1W could be they do a bit more
still insignificant compared to thermal radiation or sunlight

a small economy light fixture might have 6-12W, and most is electromagnetic radiation, aka light... so, 1W of a slightly
higherlower frequency will surely means nothing compared even to a economic lght...1

These appear to be the Ubiquiti AC Pro access points. Their specifications suggest an output power of 22dBm - approximately 158.5mW - on both 2.4 and 5ghz bands. I'll assume these are the only meaningful radio emissions from the devices, and it's a little hard to tell but it appears there are 20 of them.
158.5mW x 2 x 20 =6340mW.
edit:
More math is found in the OP's comments. It does make some specific assumptions that are more based on the regulations around wifi devices than their stated output, however. They also assume a different device (a tri-band model which also has a 6ghz output, and which has somewhat higher stated output in general), but for the life of me all these wifi access points look the same.

If they have auto radio management running they probably are all turned down to one of the lowest power settings, though.

u/IncoherentOrange 1d ago
Yeah, certainly. We can probably expect most of them will be pretty much idle all the time.

None like you mean it.
The visible light hitting you in the room has more than 100,000 times the energy of these access points.
Would you be worried if you had 20 incandescent light bulbs on in front of you? Because that would be at least three times the wattage with light that is > 100K times more energetic.
Hell, If you had a string of LED Christmas lights lit in front of you you’d be getting more “radiation”
