There is another aspect to this, the 'precautionary principle'. This
says that if you don't know the harmful level of something, you reduce
its level to ALARP, 'as low as is reasonably practicable'.
Unfortunately, of course, opinions differ very widely on what that level
is, in many cases. This is why we see concentration limits of parts per
trillion, because they are achievable (at a price), not because they are
related to known effects.
I didn't grow up in strong EM fields, but in a concentration of lead
(pipes, paint, cable sheaths) that would be regarded as horrifying now.
If that reduced my intellectual capacity, much is explained.:-P

Yes, there are very big 'safety factors' built into the requirements,
more in Europe than in USA. Much of the interest in Europe was
generated by Scandinavian trades unions concerned about 'radiation'
from CRT displays. Adverse health effects of a general
nature(headaches, insomnia, general malaise) were very likely much
more due to poor working conditions and job interest, but the unions
are very powerful.
You can't subject people to increasingly strong fields until they show
a reaction, it would be highly unethical.
