Common sense and long term experience suggests that there is no great
problem overall.

Long experience of human nature and of people not caring or thinking
about the outcomes of what they do, and much experience of Murphy at
work suggests that 'prudent avoidance' may be in order.
The values of 'prudent" and "avoidance" will vary person by person.

I long ago ran sniffers along the door seams and other orifices of
operating microwave ovens to get some feel (never literally) of
leakage levels. I found that a corded telephone often serves as a
leakage detector of sorts 'in a pinch' - and that the levels may
surprise on occasion.
Moving the mains powered alarm clock further away from your head while
sleeping is unlikely to do much harm.
Wondering about the local HV power lines when house hunting (quite
apart from the aesthetics) may be worth considering. Or not.
Super-heavy-usage cellphone users might consider using a corded
earpiece (and wonder about that) or a bluetooth headset (and wonder
about that).
Carrying a GSM cellphone, with its propensity to occasionally produce
RF bursts 'because it wants to' and well demonstrated ability to
inject low frequency signals into about any equipment that it wants
to,  in a 'breastpocket' may indeed be harmless.
And more.
