"We need to know what kind of radioactive materials are escaping, and where they are going – they don’t have a system in place for doing that now."

What They're Covering Up at Fukushima

By HIROSE TAKASHI


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. . . .

Yo: So damage from radioactive rays and damage from radioactive material are not the same.

Hirose: If you ask, are any radioactive rays from the Fukushima Nuclear Station here in this studio, the answer will be no. But radioactive particles are carried here by the air. When the core begins to melt down, elements inside like iodine turn to gas. It rises to the top, so if there is any crevice it escapes outside.

Yo: Is there any way to detect this?

Hirose: I was told by a newspaper reporter that now Tepco is not in shape even to do regular monitoring. They just take an occasional measurement, and that becomes the basis of Edano’s statements. You have to take constant measurements, but they are not able to do that. And you need to investigate just what is escaping, and how much. That requires very sophisticated measuring instruments. You can’t do it just by keeping a monitoring post. It’s no good just to measure the level of radiation in the air. Whiz in by car, take a measurement, it’s high, it’s low – that’s not the point. We need to know what kind of radioactive materials are escaping, and where they are going – they don’t have a system in place for doing that now.

  1. Look, you are partially right. The reporters don't know the difference between airborn radio isotopes and radiation. The high measurements at the plant are radiation....which are of no concern to anyone outside of the plant site because they drop as a square of distance. Of course air samples are being taken and analysed..... but hey, if the journalists can't understand the difference between radioactive material and radiation there is absolutely no point in reporting Bq/ml airborn concentrations of various isotopes. The main isotope in the plume is Iodine 131. The good news is that it has a short half life of 8 days so it will soon decay away. All the data that I have seen gives me no concern about about airborn radioactivity. If someone would pay my airline ticket I would go to Japan today and help out with the real emergency, people injured, homeless without food and clean water. I would not be worried about my uptake of radioactive isotopes. I am a Health Physicist. By the way every one eats and drinks and breaths in radioactive material into their bodies every day. It is from natural sources, but as far as radiation to the body, the body doesn't know the difference. Look up Radon and Potassium 40 and Carbon 14 for just a few. Our body is always being irradiated and all life has been from the beginning of the world.
