Re: Airport screening and medicine
OK, so the dose to his medicine was 50x less. That's more than 10x. I said
that the dose from the x-ray machine was more than an order of magnitude
less than what it'd receive during the flight. I'm not sure what your
problem is with what I said. I even pointed out what an order of magnitude
meant.
The individual did not say he was a flight crew member (even pilots fly
more than 20 times/year). I'm not aware of anyone who has flown for a 365
days continuously.
The number of publications that discuss peoples' concerns about any subject
are indeed numerable (not innumerous), although I doubt it's worth the
effort. The number of reputable (i.e. peer-reviewed) publications that
discuss actual harm to women employed by airlines is quite numerable, and
small. The number of reputable (i.e. peer-reviewed) publications that
discuss the lack of actual harm to people ( I hate excluding any person
based on biology) employed by airlines is quite numerable, and larger.
And even after looking at the posting again, I'm unsure why you're going
off on hormesis.
There are references included in my posting that enable people to use
peer-reviewed tools and publications to evaluate their doses during flights.
Just trying to he helpful : )
(Obviously my own opinions)
