[2021] Radiation levels at Fukushima plant far worse (10 Siverts)

Exceedingly high radiation levels found inside crippled reactor buildings at the Fukushima No. 1 nuclear plant were labeled by nuclear regulators as an “extremely serious” challenge to the shutdown process and overall decommissioning of the site.

The Nuclear Regulation Authority (NRA) said a huge amount of radioactive materials apparently had attached to shield plugs of the containment vessels in the No. 2 and No. 3 reactors.

Radiation levels were estimated at 10 sieverts per hour, a lethal dose for anyone who spends even an hour in the vicinity, according to experts.

Radiation levels at Fukushima plant far worse than was thought

The finding would make it exceptionally difficult for workers to move the shield plugs, raising the prospect that the plan to decommission the reactors will have to be reassessed.

Toyoshi Fuketa, chairman of the NRA, noted that removing the highly contaminated shield plugs added to the enormous difficulty of retrieving nuclear fuel debris, the most daunting part of the decommissioning process.

“It appears that nuclear debris lies at an elevated place,” he said at a news conference earlier this month. “This will have a huge impact on the whole process of decommissioning work.”

A shield plug, made of reinforced concrete, is circular in shape and measures about 12 meters in diameter.

It has a triple-layer structure, with each layer about 60 centimeters thick. It is placed above the containment vessel like a lid on the top floor of a reactor building.

The shield plug blocks radiation from the reactor core at normal times.

When nuclear fuels need to be replaced, workers remove a shield plug to gain access to the interior of the containment vessel.

In a study that resumed in September after about a five-year hiatus, the NRA carried out fresh measurements of radiation levels in the vicinity of the shield plugs of the No. 2 and No. 3 reactors.

The study was undertaken following investigations by Tokyo Electric Power Co., operator of the plant, and other entities, which had shown extraordinary levels of radiations there.

The NRA’s study found that the amount of radioactive cesium 137 was estimated at 20-40 petabecquerels between the space between the top and middle layers of the shied plug of the No. 2 reactor.

That works out to more than 10 sieverts per hour based on readings of radiation levels nearby. Radiation at such levels can kill a person if they are exposed for an hour, according to experts.

The estimated figure was 30 petabecquerels for the No. 3 reactor.

In the triple meltdown triggered by the 2011 earthquake and tsunami disaster, the shield plug of the No. 1 reactor slipped out of place and was damaged by a hydrogen explosion that occurred at the reactor building.

As larger amounts of cesium 137 leaked from the No. 1 reactor through the damaged plug, the amount of the radioactive material attached to its shield plug was estimated at 0.16 petabecquerels, considerably lower than for the No. 2 and No. 3 reactors.

In contrast, the shield plugs for the No. 2 and No. 3 reactors remained relatively unscathed, blocking a huge amount of radioactive substances that leaked from their containment vessels from escaping into the atmosphere, according to the NRA.

TEPCO announced Dec. 24 that the removal of nuclear fuel debris will be postponed to 2022 or later, rather than the initially scheduled 2021, due to a delay in the development of equipment to carry out the work.

The Battle of Chernobyl - Best Doc On Chernobyl

With the Fukushima Disaster spiraling out of control, and with Tepco reporting they have spotted cracks in 8 places on the steel brace that holds a 120-meter vertical pipe standing between the number-1 and number-2 reactor. In an area that is contaminated with high levels of radiation measuring 10 sieverts per hour. TEPCO are now wondering how they would be able to send in workers without them dying on the spot.

Russian Bio-Robots Working in Extreme Radiation 1700 Rads - 17.000.000 Millisieverts/Hr

You might ask why don't the Japanese that are so good with Robots and electronics, just don't send in Robots to do the work instead of humans? Well like the Russians learned early on and also TEPCO. The radio controlled robots malfuntion because of extreme radiation. Extreme levels of radiation will interrupt electronics and microships from functioning properly.

That is why it is high time to revisit the Battle of Chernobyl documentary that video shows us how the Russian workers called Bio-Robots suited with 30 kg of lead clothing and plated vehicles dealt with the +10 Sieverts per hour radiation exposure on top of the Single Reactor in Chernobyl. 

All the lies that TEPCO have said these past years that everything is under control, there was no meltdowns, no contamination in the waters, Tokyo is safe and everything will be alright. Smile and radiation wont hurt you.. Everything and everyone is starting to look at them with disgust and screaming for their heads.

This documentary of the Chernobyl disaster is a MUST SEE! The Battle of Chernobyl is the best made movie so far. The Battle of Chernobyl contains rare original footage, pictures and good re-enactments. This along with interviews with political leaders, scientists, soldiers, journalist, photographer and several military personnel and real footage of the damaged nuclear reactor.

There are some very good comments made in this movie from the people involved. And this documentary is something you must watch to better understand the extent of the Fukushima disaster. The things the Russians did to prevent a second explosion is something many can't really grasp. The Battle of Chernobyl tells this story very well.

Movie Player

The Battle of Chernobyl tell us many important things about the situation at Fukushima Daiichi. We get to hear from a worker at reactor unit 4 about the beautiful colors going up into the night sky 1000 meters during the reactor explosion. The cover-up and Mikhail Sergeyevich Gorbachev the former Soviet statesman. Also rare footage from the town Pripyat the day after where we get to see the flashes on the camera during filming caused by radiation.

Russian Bio-Robots working with 30 kg lead suits in 17.000.000 Millisieverts/Hr

We get to hear from the brave workers called Bio-Robots recieving 1700 rads or 17.000.000 Millisieverts/Hr radiation levels when working on top of the reactor. They could only work for 45 sec at time before the radiation would be to much. Working with 30kg makeshift lead suits. Some had nosebleeds coming down afterwards. They felt like they had been sucked dry by a vampire. When their eyes started to hurt and they started to taste a metallic taste of lead in their mouths they knew that they had reacherd their limit. But they did their job even picking up the 15.000.000 Millisieverts/Hr contaminated concrete blocks with their hands trowing it of the reactors roof. In the end they had reduced the radiation levels with some 30%. Got a $100 bonus and a certificate. The Bio-Robots can't work anymore because the high radiation levels they were exposed to. Many not even in their 50s now are unable to make a living because of this.

Russian Radio Controlled Robot malfuntioned because of extreme radiation

The Bio-Robots were used because the radio controlled equipment, looking like something you would send to the moon that should do the job malfunctioned because the extreme radiation affected the electronics. Before this six hundred (600) helicopter pilots were employed to drop lead over the open reactor to help cool it down and put out the fire. All the pilots were exposed to lethal doses of radiation, and “all” six hundred pilots died.  

Not only did the pilots die, but as the lead vaporized with the heat, many people, including children in the city, inhaled high doses of lead. Since there was concern that the meltdown would contaminate the water table below, 2,500 miners were dispatched to manually dig below the plant to make way to encase the reactor core.  Half of those miners died, and many others became very ill with radiation sickness.

The work done and the cost of 18 Billion Dollars in todays money was important not only to limit the radioactive material from spreading around the world but also to prevent a second nuclear explosion. An explosion with the potential of rendering all of Europe uninhabitable. Some would say that the lead dropped in the reactor to try and cool it down were the wrong thing to do. But with the severity of the disaster it was the only right thing to do.

In all, it was said that 500,000 people (other accounts claim 600,000 people) were dispatched to the Chernobyl plant to contain the reactor, half of whom have died since then as a result of radiation exposure and today about 200,000 are on permanent disability due to sicknesses from their radiation exposure.

Again this is a must watch for anyone. Really well done documentary about the Chernobyl disaster. And I really hope you take what is said to heart. And look at what the Russians did in 1986.

Arnie Gundersen 10+ Sievert Radiation Levels at Fukushima

This video is from Aug. 4 2011

Mr. Gundersen Fairwinds.com is talking on Skype Video about the extreme radiation levels 10+ Sieverts/Hr or 10.000 Millisieverts/Hr found OUTSIDE at the Fukushima Daiichi Nuclear Power Plant. Gundersen say he use Rem to measure radiation Rem (Roentgen Equivalent Mammal/Man; 1 rem=0.01 Sv). This means the Roentgen radiation exposure measured outside the Fukushima Daiichi plant is 1000 rems. Well actually the radiation levels went off the scale so we can only say for sure that there are 1000+ rems found.

The disturbing thing about this is the extreme radiation level was found in a stack used to vent hot gases from the reactor into the air. The hot gases containing radiation condensed going up the pipe turning back into water and over time collected at the bottom. This means the extreme radiation levels found are only the tip of the iceberg. They have been venting this into the air for at least 140 days already.

Highest radioactivity level detected at nuke plant

The operator of the Fukushima Daiichi nuclear power plant says it has detected 10,000 millisieverts of radioactivity per hour at the plant. The level is the highest detected there since the nuclear accident in March.

Workers of Tokyo Electric Power Company, or TEPCO, on Monday measured the extremely high level of radioactivity near pipes at the bottom of a duct between the No.1 and neighboring No.2 reactor buildings.

According to the science ministry's brochure, if a human received 10,000 millisieverts, they would likely die within a week or two.

TEPCO has restricted access to the site and the surrounding area.

The utility says the workers taking measurements on Monday were exposed to up to 4 millisieverts.

The utility says the high level of radioactivity was detected because the pipes were used to vent air containing radioactive substances from the crippled No.1 reactor on March 12th.

The utility had detected a maximum of 1,000 millisieverts per hour outdoors in debris, and also found a maximum of 4,000 millisieverts per hour indoors in one of the reactor buildings.
