Japanese Cabinet Secretary Yukio Edano, says nuclear danger area expanded to 80km (50 miles).
Reports that the U.S. has expanded the area to 90km, Edano could not confirm.
Edano also asking all medical personnel in Japan to prepare to help. Expectant women have priority.
Japan Defense Minister, Toshimi Kitazawa, just said that radiation levels at Fukushima Daiichi are too high to safely conduct ground operations, as well as aerial operations. Despite the dangerous radiation levels, the situation is so bad that they have decide to re-start cooling operations.
At an altitude of 300 meters (984 feet), 87.7 millisieverts (87,7oo microsieverts) were read.
Police spraying water from their riot control trucks. Japanese Self Defense Forces are bringing in more water trucks, which are being supplied by the U.S. military. The plan is to alternate between ground and air water spraying.
Spraying with trucks being done from outside the plant because ground radiation levels are too high to get people on site.
Officials at INL are watching events in Japan very carefully. The INL has their own reactor, and it is the location for the first nuclear plant in the United States.
The INL continues to be active in nuclear power, and clean up, applications.
INL officials say the use of sea water to cool nuclear reactors has never been done before. It is a true last ditch effort.
Japanese officials saying all six reactors at Fukushima Daiichi, are in trouble, but the immediate, and most serious situation are reactor 3 & 4. This is because spent fuel rods are overheating, or on fire.
Police from Tokyo have begun using their riot control water trucks to spray water on reactor 4, Fukushima Daiichi.
The JSDF has resumed dropping water on reactor 3, despite high radiation levels. Officials say the overheating situation has become so bad that they had no choice but to have helicopter crews be exposed to high levels of radiation.
Officials say workers on the ground, and helicopter crews are wearing protective clothing. A lead plate has been attached to the bottom of the CH-47 copter. Officials say reactor 3 requires at least hundreds of dumps of water from helicopters. This is a logistical problem, regardless of the radiation, which is why they have brought in police, and fire, water trucks. Another 11 water trucks are heading to the plant.
TEPCO, operator of the Fukushima Daiichi, says they are trying to lay new electric power lines to the plant. This is an attempt to restore power to the plant, to help fight the disaster. All earlier attempts to restore power failed.
Robert Alvarez, senior scholar at the Institute for Policy Studies, says the situation is so bad that “This is a situation where people may be called in to sacrifice their lives. … It’s very difficult for me to contemplate that but it’s, it may have reached that point.”
The U.S. military has banned service members from coming within 50 miles (80km, that’s much larger area than Japan’s 20-30km) of the Fukushima Daiichi plant. The U.S. Embassy, in Japan, is tell all U.S. citizens who live near the plant to stay indoors.
White House spokesman Jay Carney said “…the advice the Japanese government is giving…is different than the advice we’d be giving if this incident happened in the United States.”
After watching interviews of tsunami survivors it has become clear that there was very little time between the 9.0 quake and the first tsunami surge.
Most survivors say there was less than 15 minutes from the time of the quake to the tsunami impact. An environmental activist from the United States, Brian Barnes, says where he was it was less than 7 minutes. He says most of the people of Otsuchi, where he was, died. The city is wiped out. Barnes survived because he immediately drove to higher ground after the quake, with the tsunami showing up after he got to the top of the hill.
Most survivors say any emergency preparedness training they underwent in the past, did not prepare them for this.
The Japanese government is turning to hotels to house evacuees from the ongoing nuclear disaster.
People living within 20km of the Fukushima Daiichi plant were ordered to evacuate. Many people discovered that the shelters they were supposed to report to were already full of quake/tsunami survivors.
A Japanese doctor, who specializes in radiation sickness, says microsievert is OK (in general). Millisievert is bad, because it is 1,000 times more than microsievert.
Japanese officials have given radiation levels in both sieverts, sometimes correcting each other during the press conferences. This is causing confusion, and adding to people’s mistrust of officials.
One official reading was in 400 millisievert, which is 400,000 microsievert. Apparently the 400 millisievert report is correct. However, some people thought they meant 400 microsievert, which would have been a much safer reading.
The way officials are scrambling to keep the reactors, and spent fuel rods, from melting down, indicates that radiation readings, from around the plant, are probably in the millisievert range. One report said that readings around the plant are 1.4 millisievert per hour (that’s 1,400 microsievert).
