Fukushima Diary: A citizen blog by and for Japanese citizens. Includes many reports of radiation sickness symptoms and high levels of radiation in Japan.

This link includes a 5-min video of a citizen meeting in Japan with government officials, who are not answering their pleas for evacuation from highly contaminated areas and testing of urine samples. It also includes many links to Japanese radiation monitoring data.

Japan Held Nuclear Data, Leaving Evacuees in Peril

Aug. 8, 2011
A second meltdown likely occurred in the No. 3 reactor at the Fukushima No. 1 nuclear power plant, a scenario that could hinder the current strategy to end the crisis, a scientist said.

“Evacuees should receive compensation in line with radiation levels in neighborhoods.” Only those who have evacuated from government-designated evacuation zones are eligible for provisional compensation by Tokyo Electric Power Co., the operator of the crippled Fukushima No. 1 Nuclear Power Plant, or to receive donations that the Japanese Red Cross Society and other organizations have collected from the general public. No compensation has been paid to households with children who have evacuated from areas that are more than 30 kilometers away from the crippled plant and where high levels of radiation have been detected. It is hard to understand that the government has failed to rectify such unfairness. Read more at:

March 15 estimated 2 quadrillion becquerels per hour, according to TEPCO. “The government and utility also said the amount of radioactive materials currently released from crippled reactors 1, 2 and 3 is estimated at about 1 billion becquerels per hour at most. According to them, the surrounding area’s radiation level would be a maximum 1.7 millisieverts per year in this case. On March 15, the amount was estimated at 2 quadrillion becquerels per hour, Tepco said.”

For the first time, Tepco said it will take about three years to move through the medium-term range of the crisis, which includes getting the fuel rods out of the spent fuel pools and constructing a full-scale water treatment facility at the site.

NISA on Monday more than doubled its estimate of the radioactive material ejected into the air in the early days of the Fukushima nuclear crisis to 770,000 terabecquerels.

The nuclear safety agency also issued its own assessment of the cores in reactors 1, 2 and 3 at the Fukushima No. 1 power plant, assuming that all of them melted, and said it was possible the meltdowns in units 1 and 2 happened faster than the time frame estimated by Tokyo Electric Power Co. The assessment by the Nuclear and Industrial Safety Agency is expected to be reflected in Japan’s report on the accident at a ministerial meeting being hosted by the International Atomic Energy Agency later this month.

In April, Japan raised the severity level of the crisis to 7, the maximum on the International Nuclear Event Scale, putting it on par with the 1986 Chernobyl disaster. At the time, NISA believed that 370,000 terabecquerels of radioactive material had been ejected from reactors 1, 2 and 3. That was revised Monday after NISA found that more material escaped from reactor 2 than thought.

Level 7 accidents correspond to the external release of material equal to tens of thousands of terabecquerels of radioactive iodine 131. One terabecquerel equals 1 trillion becquerels. NISA said the melted fuel in reactor 1 fell to the bottom of the pressure vessel and damaged it at about 8 p.m. on March 11, about five hours after the quake. In reactor 2, a similar event took place at about 10:50 p.m. March 14, it said. However, Tepco says the pressure vessel in reactor 1 was damaged on the morning of March 12, and the pressure vessel in reactor 2 in the early hours of March 16.
A NISA official said the assessments vary due to different water injection assumptions.

Radioactive Contamination in Japan affects much larger area than previously estimated
Japan is dangerously contaminated by radioactivity over a far larger area than previously reported by TEPCO and the central government according to new reports from multiple sources. The prefectural government of Iwate released new data that shows radioactive contamination of grass exceeds safety standards at a distance of 90 to 125 miles from the damaged Fukushima nuclear power plants.
The prefectural government found on Tuesday radioactive cesium exceeding the limit of 300 becquerels per kilogram in grass collected from pastures in four areas, including Tono and Otsuchi. The areas are located about 150 to 200 kilometers north of the Fukushima nuclear power plant. Science Magazine reports that Japanese scientists have become so concerned about the health of their children that they have initiated their own radiation monitoring program and made their own maps. The results are shocking. Read more at:,-Vast-Area-of-Japan-Contaminated?via=siderec
