Is Nest Hub radar radiation above FCC safety limit?

Having tried the Sleep monitoring feature for a few nights, I am quite happy with it. However, I am always cautious about wireless radiation though Google public disclosures have always been "very low power". I tried to google the exact power level, but I could only find "very low level".

After more searching, I finally found a FCC (governing body for radio waves) document that indicated that the Soli radar in the Nest Hub exceeds FCC safety limit. In fact, they had to get a waiver from the safety limit. The link for the FCC ruling can be found in: https://www.fcc.gov/document/google-llc-request-waiver-part-15-project-soli

Does anyone know whether the actual Nest Hub product really exeeds FCC limits? It is concerning as the device is 2 feet from my head 8 hours a day. I am actually thinking about replacing with the Echo Show 8...

@waldoputty

This FCC ruling does not seem to address any potential health concerns, but only potential interference with other radio wave transmissions and possible safety concerns related to such transmissions.

good to know. thanks

i will search some more about this. i see the radar uses 60 ghz radiations, which is much higher frequency than the 1-6 ghz in ordinary wifi and cellphones. will just search for 60 ghz safety instead... thank you

@MplsCustomer

did a little more searching. found https://ui.adsabs.harvard.edu/abs/2022JIMTW..43..260K/abstract

60 ghz is absorbed by the top layer of skin and cornea. most importantly, tthere is a threshold for cornea damage for 400 mW/cm2 for closed eye lids. yes, it is much higher than the 13 mW total peak power for the radar. but this is 8 hours a day at 2 feet away.

no thank you google. i am returning it.

i like no contact sleep monitoring, but there are other sleep monitors...
