Z-Backscatter Van.
Full Version: RL Security Device -- X-Ray Van
You know, I don't tend to be much of an alarmist, but does it bother anyone else that they could just drive by and irradiate people?
I mean, when you get an X-Ray at the doctor's, the techs leave the room to avoid getting unecessary radiation...
Now,what the hell, we'll just put it in a van and drive around with it taking pictures.
Screw privacy issues, I have health issues with this one...

That rocks.
Radiology technitions leave the room because they do their job dozens of times a day 5-7 days a week for years. If they didn't they would accumilate an unsafe number of rads/time.
However, being exposed once by a random X-ray van isn't damgerous at all. The thing about radiation is that you can't avoid it no matter how hard you try. Everything is radioactive to some degree. Background radiation is everywhaere. That is why it is called background radiation. A little bit of extra radiation every once in a while isn't going to hurt you.

I have both.

Unless your pregnant. Then it is extremely dangerous to the health of the child.
The X-ray van has two parts to it. There is the transmitter/emitter and the receiver. They have to be lined up, within a set distance of one another and coordinated so that the signal will be received. Otherwise its a really shoddy microwave. 
So don't worry about this badboy being driven around at random. To scan a box car or tractor/trailer requires a bit of doing to get it ready and running. Trust me, you would notice if they were trying to set this thing up outside your house.

Here's a general idea about radiation amounts:
*Background radiation is equal to about 0.001 Sieverts per year.
*A single medical X-ray produces about 0.2 mSv (0.0002 Sv)
*Nuclear reactor workers are permitted to receive up to 0.05 Sv/year
*An exposure of 1 Sv in an hour results in radiation poisoning
*Exposure to 3 to 5 Sv in an hour results in death in 50% of the cases
You'd need 5 normal medical x-rays to equal your annual natural radiation dose, and 250 to reach the legal limit for a nuclear industry worker.
Backscatter x-rays lower the dosage further, requiring only 30 to 100 microSv for a typical full body backscatter x-ray. You'd have to get 500 to 1700 backscatter to reach the limit for a nuclear industry worker, and you'd need 10,000 to 34,000 to produce detectable radiation poisoning effects.

Did it say that somewhere on the webpage? I thought the point of backscatter x-rays was that the x-rays scattered back from the target (back toward the emitter) were captured rather than resorting to normal transmission-style x-rays.
http://www.physics.isu.edu/radinf/body.htm
"These devices operate on a physical process called backscatter. Backscatter uses X-rays that reflect away ("scatter back") from the low-Z material (skin, clothing) but not most high-Z material (metal). Backscatter then makes "reflections" that define the high-Z materials as separate and distinct images from low Z. "
So, in effect, what you are saying is that should you receive enough scans to be adversely affected by such a van, any harm that comes to you is likely good for the public in general? In other words, if you are such a screw up that they feel the need to scan you 34,000+ times, then you are likely a really bad criminal or a serious threat to the general population. or, by some piece of bad luck on epic proportions you are constantly living near such individuals.
That, or the operator left the van parked overnight and forgot to turn the damn machine off.
lol

According to gov. guidelines I believe that falls under 1 application.

Good for the gene pool, at least. It would take some talent to get 34,000 doses (and that's only enough to produce marginal radiation poisoning).

Or that, in which case the lawsuit and medical bills won't be helping the public good.
