[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.

TEPCO Area Around Pipe as Off-Limits Extreme Radiation

Investigating the 10-plus sieverts/hour radiation at the bottom of the main exhaust duct for the Reactors 1 and 2 at Fukushima I Nuclear Power Plant, TEPCO announced on August 4 that 3.6 sieverts/hour radiation was detected at the drain pipe that connects to the bottom of the main exhaust stack for Reactors 1 and 2.

The pipe is for draining rainwater from the bottom of the exhaust stack. 3.6 sieverts/hour radiation was measured at several meters from the exhaust stack. TEPCO has designated the area around the pipe as off-limits.

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.

Robot Measure Over 5 Sieverts OUTSIDE Fukushima Reactor 1

The robot sent into Fukushima to measure radiation levels called "Packbot" did actually measure more than 5 Sieverts/Hr. This is because the meter went overscale. And not only that, the radiation levels for the meter went overscale OUTSIDE the "train room" on the second floor.

Look at the radiation readings in the picture picked up by the "Packbot". The path that the robot took is trought an air conditioning room on the second floor. At the start there was 18 Millisieverts/Hr but this number quickly rise. It jumps to 300 Millisieverts/Hr almost instantly inside the air conditioning room and climbes to 2000 Millisieverts/Hr. When the Packbot is approaching the opening at the "train room" the radiation level goes overscale and spikes the 5000 Millisieverts/Hr radiation detector used by the remote controlled "Packbot".

It's a safe bet to say that if the radiation level increase in a linear fashion and nothing is shielding the radiation. Then the numbers would probably be in the 10+ Sieverts/Hr inside the "train room". But there are some heavy equipment that is shown in the picture that could shield the radiation levels measured by the Packbot. If so then who knows how high the radiation is inside the room.

This is an earlier picture taken from inside the Reactor Building, Unit 1, Fukushima Daiichi Nuclear Power Station. Gamma camera view from the large equipment service entrance to the south-side airlock, 22 May 2011. Measurement unit is counts per second (cps). TEPCO. We clearly see that the second floor have high radiation levels.

Extreme Radiation Levels at Fukushima Daiichi Plant

Tepco Reports Second Deadly Radiation Reading at Fukushima Nuclear Plant
By Tsuyoshi Inajima and Kari Lundgren - Aug 3, 2011 12:24 PM GMT+0300

Tokyo Electric Power Co. reported its second deadly radiation reading in as many days at its wrecked Fukushima nuclear plant north of Tokyo.

The utility known as Tepco said yesterday it detected 5 sieverts of radiation per hour in the No. 1 reactor building. On Aug. 1 in another area it recorded radiation of 10 sieverts per hour, enough to kill a person “within a few weeks” after a single exposure, according to the World Nuclear Association.

Radiation has impeded attempts to replace cooling systems to bring three melted reactors and four damaged spent fuel ponds under control after a tsunami on March 11 crippled the plant. The latest reading was taken on the second floor of the No. 1 reactor building and will stop workers entering the area.

“It’s probably the first of many more to come,” said Michael Friedlander, who spent 13 years operating nuclear power plants in the U.S., including the Crystal River Station in Florida. “Although I am not surprised, it concerns me greatly; the issue is the worker safety.”

The 10 sieverts of radiation detected on Aug. 1 outside reactor buildings was the highest the Geiger counters used were capable of reading, indicating the level could have been higher, Junichi Matsumoto, a general manager at the utility, said at a press conference.

Upper Limit

“Ten sieverts is the upper limit for many dosimeters and almost equal to the amount that killed workers at the JCO nuclear accident in 1999,” said Tomoko Murakami, a nuclear researcher at the Institute of Energy Economics, Japan.

In that accident, then the world’s worst since Chernobyl in 1986, more than 600 people were exposed to radiation after workers inadvertently started a nuclear chain reaction while processing nuclear fuel at a plant near Tokyo. Two employees of JCO Co., a wholly-owned subsidiary of Sumitomo Metal Mining Co., died from radiation exposure.

Tepco was forced to pump water into the three Fukushima reactors after the March 11 earthquake and tsunami disabled cooling systems. The company in May estimated there would be 200,000 tons of radiated water in basements and other areas of the Fukushima Dai-Ichi plant by December.

“If nuclear fuels melted through containment chambers, Tepco will find even higher radiation readings after water in building basements is removed,” said Tetsuo Ito, the head of the Atomic Energy Research Institute at Kinki University.

Radiation Leaks

Tepco has been criticized by the government for withholding radiation data and other missteps that have worsened the crisis. About 160,000 people have been evacuated from areas stretching 20 kilometers and more from the plant.

On May 27, Chief Cabinet Secretary Yukio Edano said Tepco’s withholding radiation data was contributing to “public distrust.” The utility responded by saying it will publish in August the combined figures of radiation released into the atmosphere and in contaminated water. It hasn’t given a date for release of that information.

Radiation leaks from the Fukushima reactors have spread over 600 square kilometers, Tomio Kawata, a fellow at the Nuclear Waste Management Organization of Japan, said in a research report published on May 24 and given to the government.

Radioactive soil in pockets of areas outside the exclusion zone around the plant have reached the same level as in Chernobyl following a reactor explosion in the former Soviet Union, the report said.

Hot Spots

The threats to Japan’s food chain are also multiplying as radioactive cesium emissions from the Fukushima plant spread. Contaminated beef has been found on supermarket shelves around the country, forcing the government to ban cattle shipments from areas in northern Japan.

The latest high radiation readings are probably coming from materials released during early failed attempts to release pressure in containment vessels and vent hydrogen gas to prevent explosions that damaged reactor buildings, Matsumoto said. There were about 2,760 workers at the plant on Aug 1.

Tepco on April 17 set out a so-called road map to end the crisis by January, aiming to bring down radiation levels at the plant within three months and then achieve a so-called cold shutdown where reactor temperatures fall below 100 degrees Celsius (212 degrees Fahrenheit).

The utility needs to investigate other areas that may hold high radiation levels in line with the cold-shutdown and clean up, said Murakami at Energy Economics.

“Tepco workers and its subcontractors who know the Fukushima plant well may be the only ones that can discover such hot spots,” he said. “For people new to the plant it’s deadly.”

Half-life of some radioactive elements

Fukushima 10+ Sieverts/Hr Extreme Radiation

There have been new released photos of the hot-spots of extreme high radiation at the Fukushima 1 nuke plant. Radiation levels are above 10 Sieverts/Hr now making it a very dangerous place to be. If anyone where to be exposed to 10 Sieverts/Hr of radiation only for a short time this would mean death. Radiation sickness would come quick.

The human worker in the picture is measuring the radiation with the survey meter on the stick. On the ground we can see that attempts have been made to spray a green pale rasin on the ground to limit dangerous radioactive particles from flying into the air when work is in progress.

The photo taken by the gamma-ray camera show 2 hot-spots of high radiation. Radiation levels are so high that the gamma-ray camera goes of the scale also. With the color red being the extremely high radiation levels measured. If we look at the left hot-spot we can see the big pilar at the back of the destroyed building. This is where the human worker was standing measuring the radiation with the survey meter on the stick.

Radiation is at seriouse levels at Fukushima. Prof. Kodama said, severals of Hiroshima/Nagasaki blasts worth of radiation, only difference is the radiation wasn't pumped vertically by the mushroom clouds.
