If you're worried about the radiation from these scanners you really shouldn't be flying.
I assume you're making reference to the cosmic radiation exposure from the flight itself?
In very simple terms, whilst cosmic radiation is very varied and complex, it is so insignificant that dosimetry studies aren’t even considered pertinent for less than 200 hours at altitude (which is the lower limit to provide 1 microsievert) It’d take well beyond that to receive values of concern. Airline personnel face on average 2-5 mSv (after 1000 hours) alongside the 3 msV that natural and man-made sources provide to the average person. Regulations provide limitations of up to 20 mSv/year averaged over 5 years and no more than 50 mSv in any given year. Here is the
WHO’s info sheet and their slightly
more gentle website.
What if I were to tell you that I’m currently involved in Biochem/Biophy research in conjunction with the
Stroud Lab at UCSF and by extension through him personally have enjoyed conversations with not only
John Sedat himself but his wife
Elizabeth Blackburn. Why am I name dropping? Because she’s a Noble holder in Medicine and was once on the President’s council on Bioethics, Sedat is a member of the National Academy of Science and Stroud himself is significantly involved in
cancer research and no less than a founding fellow of the Biophysical Society.
Both Stroud and Sedat wrote a letter to John Holdren, Assistant to the President for Science and Technology pleading for further studies into the machines and their safety after their preliminary investigation raised serious red flags. So because it’d make no sense for me to try and curtail their already layman ready text,
read it for yourself.
There has of course since
been a reply but it is full of bad science and double-talk. They are currently working on a reply to this poor response and i assure you it will have far more signatories of significance to carry it's weight this time (probably including
David Brenner). What's infuriating is that there's another technology using millimeter-wave imaging that has had all of the relevant studies performed and was cleared of any reasonably risk posed. But, despite being cheaper to make, some lobbyist in Rapiscan's pocket clearly has some people under their thumb as this more expensive, less efficient, lower resolution and less understood machine is being bought and deployed in greater numbers.
Also worth noting is that all of this focus is on individual risk which is flawed logic; even if the individual risk is 1 in 20 million (that's a number floating around at the moment, sorry I don't recall who from) there are 700 million individuals that will face these machines in a year. Fun soundbite, if the risk is indeed 1:20,000,000 for cancer, the machines pose a higher threat than terrorism itself 1:30,000,000 (not restricted to airline terrorism).
The concern is real, I couldn’t care less that they would see a semi-naked picture of me that
CAN be stored despite representatives continual lies that images are instantly deleted it’s the real health risk that exists and has been completely ignored that worries me, nobody of any consequence or intelligence has had the ability to study these machines (or perhaps have been muzzled from releasing the pertinent values). Which is why this December when I fly back home, I’m opting out. I seriously suggest everyone do the same.
There are better ways to go about airport security (
Israelification) and the TSA have no legal position to be employed in American airports at this point as two years have passed since their placement. The airports are now free to hire their own teams and use their own procedures, the government is blocking this with threats of liability should an attack occur. So, whilst we're being looked at more than ever, bag-monkeys are still allowed to travel to the airport, into the secure area, handle luggage and work in and around the airplane without being searched or scanned once. Their background checks take over 6 months, they are allowed to work whilst it's being processed. Feel safer? This really is a Security Theater.
