“Melted Core Outside the Containment Vessel”

Hiroaki Koide of Kyoto University Research Reactor Institute is quoted by Mainichi Shinbun as saying that the melted core of the Reactor 1 is not just out of the Reactor Pressure Vessel but out of the Containment Vessel.

From Mainichi Shinbun, Koide’s comments only (5/16/2011):

小出裕章・京都大原子炉実験所助教は「電源喪失で原子炉が冷やせなくなれば、早い時期に炉心溶融に至ることは想定できていたはずだ。燃料の損傷が限定的だとしてきた東電の説明は完全に誤っていたことになる。データの公表も遅すぎる」と指摘する。

Hiroaki Koide of Kyoto University Research Reactor Institute points out that “[TEPCO] could have foreseen the core melt at an early stage when the cooling of the reactor stopped due to the power failure. TEPCO’s assessment that the damage to the fuel was limited has turned out to be completely wrong. The disclosure of the data came too late.”

 東電は今回の解析で「圧力容器の損傷は大規模ではない」と説明するが、小出助教は「圧力容器は完全に破損し、溶けた燃料が格納容器の底に穴を開け、原子炉建屋の地下に大量の汚染水が漏れ出す原因になっている」と推定する。

According to TEPCO, the data analysis shows that damage to the RPV is not extensive. However, Koide thinks “The RPV has been completely damaged, the melted core bore a hole at the bottom of the Containment Vessel, causing the large amount of contaminated water to leak into the ground beneath the reactor building.”

500 Million Bq Of Radiation Released Today From Daiichi Reactor No.1 09.05.11

By opening the double-entry doors, air containing about 500 million becquerels of radioactive substances is believed to have been released into the atmosphere from the upper part of the No. 1 reactor building, which was damaged in a hydrogen explosion that occurred in the early days of the nuclear crisis.

Deadly Silence on Fukushima 09.05.11


I received the following email a few days ago from a Russian nuclear physicist friend who is an expert on the kinds of gases being released at Fukushima. Here is what he wrote:

“About Japan: the problem is that the reactor uses “dirty” fuel. It is a combination of plutonium and uranium (MOX). I suspect that the old fuel rods have bean spread out due to the explosion and the surrounding area is contaminated with plutonium which means you can never return to this place again. It is like a new Tchernobyl. Personally, I am not surprised that the authority has not informed people about this”.

I have been following the Fukushima story very closely since the earthquake and devastating tsunami. I have asked scientists I know, nuclear physicists and others about where they find real information. I have also watched as the news has virtually disappeared. There is something extremely disturbing going on and having lived through the media blackout in France back in April and early May 1986, and speaking to doctors who are deeply concerned by the dramatic increase in cancers appearing at very young ages, it is obvious that information is being held back. We are still told not to eat mushrooms and truffles from parts of Europe, not wild boar and reindeer from Germany and Finland 25 years later. People need answers, data and honest information to help them deal with what is going on.

Media blackouts, propaganda and greedy self-interested industries, of any kind, who allow human beings’ health to be affected, and deaths to occur, must be stopped now. That senior TEPCO man and the leading nuclear academic in Japan did not break down crying and resign their positions because all was well at Fukushima.

Fukushima’s No. 1 Reactor 7OO Millisieverts per hour Detected


The operator of the Fukushima Daiichi nuclear power plant found that the radiation level of the building housing the troubled No. 1 reactor stood at up to 700 millisieverts per hour, the government’s nuclear agency said Monday, citing the need for radiation shielding to proceed with work to bring an end to the nuclear crisis.

High Levels Of Radioactive Strontium Detected At Fukushima Daiichi 09.05.11

Tokyo Electric Power Company has detected high levels of Radioactive Strontium with a half life of 28.8 years from soil inside the compound of the Fukushima Daiichi nuclear power plant.
Strontium is chemically similar to calcium, and tends to deposit in the blood and bone marrow.

So How does strontium-90 work and how can it affect my health?

It is possible to breathe in particles or dust containing a chemical compound of strontium-90. If this compound dissolves in water, the chemical will dissolve in the moist surface inside the lungs. Strontium will then enter the blood quickly. If the chemical form of strontium does not dissolve in water easily, a small amount may remain in the lungs. When you eat food or drink water containing strontium, only a small amount leaves the intestines and enters the blood. Strontium can also pass through the skin. Once strontium enters the blood, it flows to other parts of the body. It enters and leaves cells easily. In the body, strontium acts very much like calcium. A large portion of the strontium will build up in bones. In adults, strontium mostly attaches to the surfaces of bones. In children, strontium may create the hard bone mineral itself, thus being stored in the bones for many years. Eventually, strontium will dissolve from the bones and return to the blood to be used again to grow bone, or to be expelled through urine, waste matter or sweat. The harmful effects of strontium-90 are caused by the high energy effects of radiation.

Since radioactive strontium is taken up into bone, the bone itself and nearby soft tissues may be damaged by radiation released over time. Bone marrow is the most important source of red blood cells, which are depleted if the strontium-90 level is too high. Some cancer patients are given injections of radioactive strontium ( Sr) to destroy cancer tissue in the bone marrow. Problems from lowered red blood cell counts include anaemia, which causes excessive tiredness, blood that does not clot properly, and a decreased resistance to fight disease.

Radioactive strontium probes are used to destroy unwanted tissue on the surface of the eye or skin. If used for eye surgery, this results in eye tissues becoming red and sore, or very thin after a long time. Thinning of the lower layer of the skin has also been reported in animal studies. In animal studies, exposure to strontium-90 caused harmful reproductive effects. These effects happened when animals were exposed to doses more than a million times higher than typical exposure levels for humans. Animals that breathed or swallowed radioactive strontium had lowered blood cell counts. It is not known if exposure to strontium-90 affects human reproduction.

Strontium-90 is considered a cancer-causing substance because it damages the genetic material (DNA) in cells. In one geographical location near a nuclear weapons plant, an increase in leukemia (a form of cancer) was reported in people who swallowed a large amount of strontium-90 in water. In animal studies, researchers reported cancers of the bone, nose and lung, as well as leukemia. Animals receiving high doses of radiation to the skin developed skin and bone cancer.

How is strontium-90 poisoning treated? Strontium-90 poisoning is treated in the same way as other radiation exposures. There are no direct treatments for strontium-90 exposure.

Tokyo Electric Power Company  said it found 4,400 becquerels of radioactive strontium 90 per kilogram of dry soil. In March, strontium was also detected in soil and plants outside the 30-kilometer zone around the Fukushima plant. A director of the Japan Chemical Analysis Center, Yoshihiro Ikeuchi, says humans could inhale strontium when wind stirs up the radioactive substance, but the amounts would be very limited. He says the current levels won’t be a health hazard to plant workers wearing face masks, but monitoring of strontium levels in the air is needed.
