News about nuclear accident in Fukushima in June 2011
- Highly radioactive debris found at Fukushima plant
On Monday, a piece of debris about 5 centimeters in diameter with radiation levels of 950 millisieverts per hour was removed from the west side of the Number 3 reactor building. It had been found on Saturday.
In May, debris with a radiation dose of 1,000 millisieverts per hour was discovered in the area, while rubble contaminated with 900 millisieverts per hour was found in April.

- Agency doubles radioactive release estimate in early days of crisis
The government's nuclear safety agency more than doubled its estimate Monday of the amount of radioactive materials emitted into the air during the early days of the nuclear crisis at the Fukushima Daiichi power plant, saying that the amount is believed to have totaled 770,000 terabecquerels.
The agency also issued its own assessment of the conditions of the Nos. 1 to 3 reactor cores based on the assumption that they suffered meltdowns, and pointed to the possibility that the process in the cases of the Nos. 1 and 2 reactors may have developed faster than estimated by plant operator Tokyo Electric Power Co.
- Radioactivity of materials released in Fukushima nuclear crisis revised upward
The Nuclear and Industrial Safety Agency (NISA) on June 6 revised the level of radioactivity of materials emitted from the crisis hit Fukushima No. 1 Nuclear Power Plant from 370,000 terabecquerels to 850,000 terabecquerels.
- Disaster victims manning front lines in struggle to tame Fukushima nuclear crisis
"The ones who caused the accident are now the ones making a living trying to repair it. Ironic, isn't it?" he says. He adds, however, that he is worried about how long the crisis will continue.
- Plutonium found outside Fukushima plant
Professor Masayoshi Yamamoto and researchers at a Kanazawa University laboratory analyzed the samples and found minute amounts of 3 kinds of plutonium.
The samples of plutonium-239 and 240 make up a total of 0.078 becquerels per kilogram. This is close to the amount produced by past atomic bomb tests.
This is obvious propaganda article. While plutonium 239 has a half life of 24,100 years, the profesor states that the amount is similar to past atomic tests, aka "no change", while at the same time confirms that the plutonium is from Fukushima accident.
- Madarame: Plant guidelines should be fully revised
The chairperson of Japan's Nuclear Safety Commission, Haruki Madarame, has told NHK that the engineering guidelines for nuclear power plants should be thoroughly revised as they do not include the possibility of a long-term power failure.
- Fukushima Reactor No. 1 more radioactive than ever
At the stricken Fukushima nuclear power plant, a robot sent into the building housing Reactor No. 1 on Saturday detected the highest levels of radiation measured since the crisis began on March 11.
According to the Japan Times, The Tokyo Electric Power Company (TEPCO) reported that radiation levels in the air around Reactor 1 were at 4000 millisieverts per hour, an exposure level equivalent to approximately 40,000 chest x-rays.

Contamination levels in the Japanese mountain village of Iitate are higher than in some parts of the Chernobyl exclusion zone. Its evacuation has been a painful process for residents -- and many are more afraid of resettlement than they are of radiation.
- Nuclear Event - Egypt is saved from a nuclear disaster - 3rd June 2011
A leak of radioactive water occurred the last few hours in the small nuclear facility Anshas, Egypt, after the explosion of a reactor pump. An anonymous source in the Egyptian Atomic Energy Authority told the local newspaper Rose el Youssef, which ran the headline "Egypt is saved from a nuclear disaster."
- Water treatment system tested
Tokyo Electric Power Co., which manages the badly damaged plant, is building the system and hopes to activate it in about a week so it can start cleaning the massive amounts of highly dangerous water being created at the plant in Fukushima Prefecture.
