    fixed it for ya!

  2. wizardpc Says:

    Yeah this really should be a suprise since they refused to let independent scientists check the radiation levels.

    Hmmm. Stay in the hellish chaos in Japan and be safe, or fly to Disneyland and get cancer.

    What, you mean letting people with absolutely no training in radiology run medical x-ray machines is a bad idea? UNPOSSIBLE!

    Stormy winz teh Intarwebz.

    You mean there’s reason that radiology techs have to have 2-4 years of college level training? {snicker}

    Ten times more than previously thought? That’s as vague as the initial reports out of Japan talking about radiation at 1000x normal levels, with no mention of what normal levels are.

    How many bananas are we talking about, here?

    Well the government has been less than willing to give precise numbers… They give lots of comparison to other things but few actual numbers. I doubt they truly know.

    They were allegedly going to be about .5 BED. That means that walking through the scanner was equivalent to about 5 BED. You’re up to 10 BED if you go through a round trip.

    The machines were supposed to output .05 mrem. This one was outputting .1 mrem. And it’s the first one I looked at.

    A chest x-ray is about 10 mrem. The yearly safe dose from man-made sources is 100 mrem. The reports are here:

    And all of this comes back to whether or not we are even looking at the right measurement. Normal exposures are figured as wide beams that are absorbed by your whole body. These are very narrow beams totally absorbed by the skin. To compare them and call the narrow beam safe is like saying than a high-powered UV laser is safe to shoot at someone because they get more UV radiation than that from the sun over the course of a day. It’s apples and oranges.
