I don't think it's a good idea to spread FUD based on irrational fears of 'radiation'. That has done enough damage to our lives already. These machines or no more dangerous than microwaves, GSM telephones or regular flying.

Now of course, people will respond to me citing authorities or papers claiming otherwise. However, that doesn't mean a thing. There is no issue in the world on which you can't cite someone or something seemingly relevant to support some point. However, if that point is a minority opinion, we usually trust the majority. We accept the majority opinion of doctors, engineers and other professionals in science-backed professions all the time. Straying from that principle in this specific case, because you want to believe that this case is different, is being inconsistent. Inconsistency breeds distrust, which is a reason not to behave inconsistently if you can help it. Therefore, don't just start believing stuff and spreading FUD about it because it suits you. There's nothing to complain about the radiation of these scanners, if you accept there is nothing sufficiently unsafe about microwaves, WiFi, GSM and regular flying.

Not necessarily true. Some of these machines use x-rays, which are far more dangerous than WiFi(ISM Band 2.4GHz) and GSM(<2GHz).

I Am A Physicist and well aware of that. My arguments is based on the safety ratings of these machines and the research supporting those ratings. I'm not arguing that the safety of microwaves carries over to these machines: I'm arguing the same methods of judging the safety carries over. I also didn't include regular flying for nothing. Finally, we used to be sitting behind CRT monitors all the time...

People are worried about the x-ray machines, not the microwave ones. The x-ray are by far the majority and that radiation damage is cumulative. That means that it doesn't matter how much we're getting elsewhere, we are adding to the damage unnecessarily, and the TSA workers at an even larger rate.
Re:100 Naked Citizens: 100 Leaked Body Scans by Confusion on Wednesday November 17, 2010 @03:30AM (#1913461)
Yes, X-ray machines, whose dosage is lower than the amount of X-rays you receive during a reasonable flight or when sitting behind a CRT monitor for a while. You're just repeating FUD, without having actually looked at the numbers.

  we are adding to the damage unnecessarily
That's a value judgment, based on what is 'necessary'. If these machines aren't necessary, then the argument against them shouldn't be based on some fringe notion of a health risk, but should directly focus on the fact that they are not necessary to improve safety.

The concern is that these doses, which target the skin by design, may in fact be far more damaging to that tissue than the overall radiation dose would imply.

>You're just repeating FUD

And you're just spewing out the FDA report, which has already been debunked for making false comparisons (e.g. likening the kind of radiation one receives while flying with X-ray radiation of the backscatter machines).

>without having actually looked at the numbers

It doesn't sound like you're very well versed on this stuff either, yet you have no trouble running around defending what is likely the biggest rights violation the TSA has engaged in so far.

>If these machines aren't necessary

It's been stated by several security experts (including airport security personnel) that existing techniques can detect more threats then these silly backscatter machines. These machines are only in airports because a form TSA head works for the company that produces them now.

This is exactly why you and many others fail to accept this simple factual point. I'm not defending the TSA. I'm arguing against a single, silly, unnecessary and counterproductive, argument against them. Arguing against an argument against something, does not make someone a proponent of that thing.

  And you're just spewing out the FDA report
From my study I have experience with medical applications involving these kinds of radiation. I know effects and dosages. Even if there are false comparisons, they are irrelevant: the numbers are the numbers and they are clear. Dosage: minimal. Even an additional factor 100 due to focusing on the skin is not noteworthy. The different energy might, but there are many reasons to believe it doesn't matter. Finally, the entire point is irrelevant. That it is thought the TSA needs these things in the first place, that is the problem. Focusing on this possibly associated problem does more damage to the general opinion about 'radiation', then it serves the cause of banning these machines.

  (e.g. likening the kind of radiation one receives while
  flying with X-ray radiation of the backscatter machines)
Sigh. Doctors also comfort patients by telling them the dosage of an X-ray photograph provides a similar dosage to flying to Australia. Yes, there are some caveats. Those caveats on that comparison do not debunk the FDA report. The general point of that comparison is valid. These doctors aren't lying to their patients about the risks involved.

It's absolutely not counterproductive. At the end of the day, people don't give a shit about their rights being violated. Look at what american citizens have already given up. Sure, they'll bitch about it around the watercooler, might even make a facebook group but that's as far as it will ever go. I bet you could go as far as doing full on rectal examinations and so long as accepting that was faster than not people would still do it without protest because convenience trumps almost all.

Almost. If the people think there is a chance that these things cause cancer then it becomes a life and death situation that they will do something about. A poster elsewhere has had some success with this issue with TSA workers.

I'm certainly not going to advocate making things up to get our way but real experts have come out on this requesting a more thorough study. TSA wont release various figures about the radiation. X-ray damage is cumulative. Taken all these things together I really believe there is a chance these things aren't safe and if there's even a chance of it that should be enough to block their usage. The burden of proof lies with the people who want to bring these things in, not with people who need to fly but don't want the added cancer risk.

This is a poor tact to take. The fact is that experts in the field have said, unambiguously that more research needs to be done on these things. Since this is something forced on us the burden of proof should be on TSA, not customers trying to use airport services. Until they can prove that there is no danger with these machines, they should not be used. Full stop.

It's impossible to prove such a thing, just like it's impossible to prove the sun will rise tomorrow.

  things
Yes, and other 'experts' have deemed these machines safe and noted the amount of radiation is far less than involved in frequent flying. That's why I'm referring to the majority opinion. You can always find an 'expert' with a different opinion. There are thousands of people that can call themselves experts on this subject. There are Nobel-prize laureates promoting the strangest parapsychological theories. It doesn't mean a bloody thing to invoke 'some expert'. The dosage facts are crystal clear.

What majority? Most of the "answer" has come from the group selling and/or using the machine. Are you calling into question the credentials of all the experts that spoke out claiming more research needs to be done on this? Are you qualified to do so?

  and/or using the machine
If they honestly believed those 'answers', they wouldn't have sold or used those machines. These answers are just intended to cover their asses, so they can have it both ways: sell the machines as safe on the one hand; publicly claim they 'have some reservations' on the other hand. The only thing that matters is: who certified the machines and what methods did they use. If the machines are certified for regular use on humans, why is that.

It's a wonder we are still allowed to use Nuclear Magnetic Resonance imaging, renamed Magnetic Resonance Imaging to get rid of the scary 'nuclear'. Now any notion of 'radiation' is again being ostracized. Everyone just repeats some thing they think they understood, without actually knowing anything of what is actually involved. If you feel X-rays are that scary, stop flying.

You're just spewing pro-TSA propoganda all over this thread. This is far from a closed issue, as pointed out here [1], among other places.

I'm spewing anti-anti-radiation facts. Primarily to get attention back to the actual issue: the usefulness of these machines in the first place. As for [1]: yes, fine, the effective dosage may be larger than suggested. Even if it's a factor 20, it still doesn't matter. Secondly, the 'letter of concern' mainly asks questions about some possible risks. Thirdly, it does not support the claims in this thread in any way. The OP was worried about it 'spewing radiation all over the place'. The dosage of people working there is completely negligible compared to what people inside the machine receive.

>I'm spewing anti-anti-radiation facts.

You've ignored every counter that was already provided to your "facts". That doesn't strike me as arguing in good faith.

>Primarily to get attention back to the actual issue: the usefulness of these machines in the first place.

Nonsense. If you care about people's rights, why would you want to bring the discussion to a place of utter irrelevance? The american people accepted The PATRIOT act for God's sake. Do you think they're going to give a shit about being scanned naked, so long as it's fast?

>Even if it's a factor 20, it still doesn't matter.

The damage is cumulative. How can it possibly not matter. Damage done by the X-ray doesn't "go away" right? So every little extra dosage you get is just making things worse for you. You can say it's less than taking a cross Atlantic flight but I have to take the flight. Trust me, if there were another way I wouldn't go near a plane.

I still fly. I get X-rays when I think I've broken something. I love bananas. These are all sources of radiation that I'm going to be exposed to for some benefit to me (sometimes the risk of not doing it is worse than the radiation risk) and am willing to take the risks. These scanners don't help me in any way. This is radiation I'm enduring for no benefit to me what so ever. Even if I did buy the party line about terrorists, dying in a car accident would be vastly more likely than being killed by a terrorist so I'd rather take my chances with them than with this machine.
