If it is from 5G then it's at safe levels. It's in the design of the standards.
Measuring field strengths is not as simple as some imagine. Multiple path makes it complicated. It won't stay the same over time or space. With a wavelength in the order of 5 mm and a reflecting environment, spatial variation over very short distances may be substantial.
Also 60GHz is chosen specifically because it does not go far, attenutates very rapidly with distance in air. It corresponds to an absorption line so the air itself absorbs it quite quickly.
