Comparisons with X-rays and CT scans “meaningless” — Inhaling particles increases radiation exposure by “a factor of a trillion” says expert

Hirose Takashi: The Fukushima Nuclear Power Plant Accident and the State of the Media, Asahi NewStar, March 17, 2011:

Translation by Douglas Lummis

… [Interviewer] Yo: Every day the local government is measuring the radioactivity.  All the television stations are saying that while radiation is rising, it is still not high enough to be a danger to health. They compare it to a stomach x-ray, or if it goes up, to a CT scan.  What is the truth of the matter?

Hirose: For example, yesterday.  Around Fukushima Daiichi Station they measured 400 millisieverts – that’s per hour.  With this measurement (Chief Cabinet Secretary) Edano admitted for the first time that there was a danger to health, but he didn’t explain what this means.  All of the information media are at fault here I think.  They are saying stupid things like, why, we are exposed to radiation all the time in our daily life, we get radiation from outer space.  But that’s one millisievert per year.  A year has 365 days, a day has 24 hours; multiply 365 by 24, you get 8760.  Multiply the 400 millisieverts by that, you get 3,500,000 the normal dose.  You call that safe?  And what media have reported this?  None.  They compare it to a CT scan, which is over in an instant; that has nothing to do with it.  The reason radioactivity can be measured is that radioactive material is escaping.  What is dangerous is when that material enters your body and irradiates it from inside.  These industry-mouthpiece scholars come on TV and what to they say?  They say as you move away the radiation is reduced in inverse ratio to the square of the distance.  I want to say the reverse.  Internal irradiation happens when radioactive material is ingested into the body.  What happens?  Say there is a nuclear particle one meter away from you. You breathe it in, it sticks inside your body; the distance between you and it is now at the micron level. One meter is 1000 millimeters, one micron is one thousandth of a millimeter.  That’s a thousand times a thousand squared.  That’s the real meaning of “inverse ratio of the square of the distance.”  Radiation exposure is increased by a factor of a trillion.  Inhaling even the tiniest particle, that’s the danger.

Yo:  So making comparisons with X-rays and CT scans has no meaning.  Because you can breathe in radioactive material.

Hirose:  That’s right.  When it enters your body, there’s no telling where it will go.  The biggest danger is women, especially pregnant women, and little children.  Now they’re talking about iodine and cesium, but that’s only part of it, they’re not using the proper detection instruments.  What they call monitoring means only measuring the amount of radiation in the air.  Their instruments don’t eat.  What they measure has no connection with the amount of radioactive material. . . .
