In an effort to lift the spirits of area residents as well as lighten the impact of the radiation, Abe began growing and distributing sunflowers and other plants.
"We plant sunflowers, field mustard, amaranthus and cockscomb, which are all believed to absorb radiation," said the monk.
But Abe decided not to wait for the results of the tests, believing that by taking action his team could help battered local towns shake off a sense of stagnation and give them hope.
A dosimeter placed next to her registered radiation levels of more than 5 microsieverts per hour, far exceeding government safety levels. Her house is located near a radioactive hot spot.
From her perspective, the only thing the government has done is to, on April 25, raise the acceptable radiation exposure limit for children from 1 mSv/year to 20 mSv/year.
The accident is believed to have left a mess of highly radioactive material in the No.1 to No. 3 reactors, with fuel rods and rod cases melting and reforming into disparate particles and lumps.
But IAEA rules insist that Japan will have to specify exactly how much radioactive substances have been left if the substances are removed from the reactors. That has never been done and will require new testing techniques.
The government will spend about 600 million yen ($7.84 million) developing tests to comply with the International Atomic Energy Agency rules that require Japan to identify levels of plutonium, uranium and other nuclear substances in the damaged fuel rods at the Fukushima No. 1 nuclear power plant.
After the 1979 Three Mile Island nuclear accident, the United States was not forced to submit a report to the agency under the nonproliferation rules because it was acknowledged as a nuclear power. In the 1986 Chernobyl disaster, the reactors were brought under control without removing fuel rods

Totally normal uh?
China Finds 100,000 SQ Miles of Radiation In Pacific Ocean 300 Times Higher Than Normal
China has discovered 100,000 square miles of Pacific Ocean waters, at distances up to 800 kilometers from Fukushima, with Cesium radiation levels up to 300 times normal and Strontium radiation levels up to 100 times normal.
China says a study conducted by its State Oceanic Administration has found widespread levels of highly radioactive contamination throughout Pacific Ocean.
China’s State Oceanic Administration said the tests show that the polluted area is far wider than the areas released by the Japanese government.
According to the study, the radiation survey found that over 252,000 kilometers, or just shy of 100,000 square mile,s of Pacific ocean waters was contaminated by the time the study was completed on July 4th.
The study found that the radiation has spread to distances up to 800 kilometers from the coast of the Fukushima prefecture.
According to the article, cesium radiation was found at levels up to 300 times higher than concentration levels detected in water off the coast of China.
The study also found Strontium-90 radiation levels up to 100 times higher than those found in Chinese waters.
It's not just intelhub... they have sources from China, Japan and India supporting their article.
And this ain't much of a surprise really.

Irrespective, in the post below, the author highlights the fact that the R3 blast did not produce a shockwave. With this I agree in part, and disagree in part. There is a shockwave, but it occurs under ground in the pre blast pulse. And that shockwave ignites hydrogen throughout the Fukushima plant which in turn causes enough pressure underground bouncing off the walls to make the plutonium in the UC go nuclear, and we have the big boom. Thats what the data currently indicates, but that could very easily change with new data.
Japan's nuclear safety agency today rejected a claim in British newspaper The Independent that the earthquake itself, not the subsequent tsunami, destroyed cooling systems leading to meltdowns at the Fukushima Daiichi nuclear plant.
"It is not correct," a spokesman for Japan's nuclear safety watchdog, the Nuclear and Industrial Safety Agency (NISA), told New Scientist.
(CNN) -- The Tennessee Valley Authority has approved construction on a nuclear plant in northeastern Alabama -- the first U.S. agency to do so since the Japan nuclear disaster this year. The TVA board of directors -- which approved the $4.9 billion project Thursday night -- said the Bellefonte project could create 2,800 construction jobs in north Alabama as well as 650 permanent jobs once the plant is complete. It estimates the plant will be online in 2020 and will provide enough megawatts to power about 750,000 homes in the region. The TVA still needs approval from the Nuclear Regulatory Commission before it can start construction at Bellefonte, a commission spokesman said.

A strong 6.8 earthquake struck Friday at the northeastern coast of Japan near the Fukushima Nuclear Power Plant which was severely damaged by the March 11 super earthquake and tsunami that caused the death of close to 20,000 people near Fukushima A tsunami warning was issued in the Fukushima and Miyagi Perfectures but was lifted 35 minutes later. The quake reportedly occurred at 2:36 pm (0536GMT) with its epicenter off Fukushima prefecture at a depth of 20 kilometers. Read more: www.digitaljournal.com...
On Monday, the Japanese Cabinet agreed to merge the Nuclear and Industrial Safety Agency and the Nuclear Safety Commission into a single Nuclear Safety Agency, putting the environment ministry in charge of regulating the nuclear sector. Previously, NISA operated under the Ministry of Economy, Trade and Industry. The move is seen as a significant victory for Japanese Prime Minister Naoto Kan who has been fighting to remove nuclear regulation from the influence of METI, which has a long history of promoting nuclear energy. The new entity, expected to be fully operational by next April, will be responsible for handling other nuclear-related activities, including emergency response, radiation monitoring and dealing with the threat of nuclear terrorist attacks, China's state-run news agency Xinhua reports.

Awesome D, that's 60 meters.
A rough estimate based on the elapsed time in the video :12 and best guess at ground level is that we can see roughly 30 meters height of the building in the video.
Measuring the height of the explosion we have roughly 20 building 30 meter heights (the very top of the cloud cuts off), plus the area below, so 630 meters. The cloud takes :12 seconds to travel the 630m, 52.5m/sec.
velocity (v) = 630 meter/second
velocity (v) = 226800000.00635 centimeter/hour
velocity (v) = 63000 centimeter/second
velocity (v) = 178582677.16524 foot/day
velocity (v) = 2066.9291338583 foot/second
velocity (v) = 89291338.582621 inch/hour
velocity (v) = 24803.149606299 inch/second
velocity (v) = 0.63 kilometer/second
velocity (v) = 1224.6220312956 knot
velocity (v) = 1.8513076697032 mach sea level 15 C
velocity (v) = 54431999.999878 meter/day
velocity (v) = 1409.2698639943 mile/hour
velocity (v) = 0.39146385110952 mile/second
velocity (v) = 630000 millimeter/second
velocity (v) = 2.1014537997484E-6 speed of light in vacuum
velocity (v) = 688.97637795276 yard/second
Keeping in mind these are all estimates. It's impossible to know the real height of the explosion based on the video evidence.
Low explosives are compounds where the rate of decomposition proceeds through the material at less than the speed of sound. The decomposition is propagated by a flame front (deflagration) which travels much more slowly through the explosive material than a shock wave of a high explosive. Under normal conditions, low explosives undergo deflagration at rates that vary from a few centimeters per second to approximately 400 metres per second. It is possible for them to deflagrate very quickly, producing an effect similar to a detonation. This can happen under higher pressure or temperature, which usually occurs when ignited in a confined space.
A low explosive is usually a mixture of a combustible substance and an oxidant that decomposes rapidly (deflagration); however, they burn more slowly than a high explosive which has an extremely fast burn rate.
Low explosives are normally employed as propellants. Included in this group are gun powders and light pyrotechnics, such as flares and fireworks.
High explosives are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity rates ranging from 3,000 to 9,000 meters per second. They are normally employed in mining, demolition, and military applications. They can be divided into two explosives classes differentiated by sensitivity: Primary explosive and secondary explosive. The term high explosive is in contrast to the term low explosive, which explodes (deflagrates) at a slower rate.
It would seem that the 'mushroom cloud' was a low explosive that appeared to detonate but actually deflagrated. However, due to the low velocity, it could not have been a hydrogen explosion as Tepco claims, as the velocity was too low (hydrogen velocities tend toward 1200 - 3400) Hydrogen explosive velocities. The wiki supports the idea that these low explosive deflagrations can be triggered by a high explosive blast wave.
As for the hydrogen explosion,
Hydrogen explosions in confined spaces and
Gas explosions, blast waves
The effect of localised explosions may in some situations not only cause high pressures locally but also cause high velocity flames to propagate into less confined but obstructed regions, where the high velocity of the flame may be sustained. Some recently published data by Harris and Wickens (1989) show examples of such an effect which was observed when flame propagation in repeated obstacle arrays was studied. They showed that if a flame entered the unconfined obstacle array at a high velocity, the flame was able to stabilise at a high velocity and high explosion pressure. However, if the flame had a low velocity in the beginning of the array, it was not able to accelerate to high velocities and the corresponding explosion pressure was low.
Meaning the velocity of the hydrogen blast wave would depend on how many obstacles were in the way whether or not it had the explosive pressure to act upon zircolly rods and initiate a criticality.
I have to do some more checking on the typical velocities of nuke explosions to see if they correspond to my numbers.edit on 17-8-2011 by Wertwog because: correction
