Fukushima Fatal Farce Turns Deadlier

Posted by feww on September 1, 2013

Radiation levels near Fukushima ’18 times higher’ than reported: TEPCO

Readings taken near a leaking tank at the nuked Fukushima plant on Saturday showed radiation levels were high enough to prove lethal within about 4 hours of exposure, the plant operator said.

The Tokyo Electric Power Company (TEPCO) had originally reported the radiation level near the tank was about 100 millisieverts an hour.

Now, the company says the equipment used for the earlier recording could only read up to 100 millisieverts (mSv).

The new reading, using more sensitive Geiger counters, showed levels of about 1,800 mSv per hour.

Studies of the 1945 atomic bombing at Hiroshima and Nagasaki show that 100 percent of victims whose bodies were exposed to 6,000 mSv (600,000 millirems) died from radiation. About 50 percent of victims who received 4,500 mSv (450,000 millirems) of radiation also died.

TEPCO said it had recorded radiation of 230 mSv an hour at a second tank, which was emitting 70 mSv in July. The company said it had also discovered two additional leaks: a third storage tank emitting 70 mSv an hour; and a pipe connecting two other tanks measuring 230 mSv.

The 2011 triple meltdown at Fukushima Daiichi NPP forced more than 160,000 people to abandon their homes, turning dozens of communities into ghost towns.

What is a lethal dose of radiation from a single Exposure?

Studies of the 1945 atomic bombing at Hiroshima and Nagasaki show that 100 percent of victims whose bodies were exposed to 600,000 millirems (6,000 mSv) died from radiation. About 50 percent of victims who received  450,000 millirems (4,500 mSv) of radiation also died.

(Note: Rem is a unit of ionizing radiation equal to the amount that produces the same damage to humans as one roentgen of high-voltage x-rays.  Source: MIT)

1 rem = 10 mSv or 10,000 µSv  (1 Sv = 100 rem)

Background Radiation in microsieverts per year (µSv/yr)

  • Average background radiation (US):  3,000
  • Higher altitudes (e.g, Denver): 4,000

“Safe Levels” of Radiation (U.S.)

Limits above natural background radiation levels (average 3,000 microsieverts per year) and medical radiation:

  • Occupation Limit: Maximum of 50,000 µSv (the limit for a worker using radiation)
  • Average Natural Background: 3,000 µSv

[Note: Lifetime cumulative exposure should be limited to a person’s age multiplied by 10 millirems, e.g., a 70-year-old person, 70,000 millirems.]

Adults

  • Max single dose for an adult: 30,000µSv
  • Annual total dose: 50,000µSv

Under 18

  • Max single dose for a person aged under 18 years: 3,000µSv (whole body equivalent)
  • Annual total exposure: 5,000µSv

Fetal Exposure

  • Maximum limit for fetal exposure during gestation period:  500 µSv per month above background levels

Medical

  • Single Chest X-ray (the whole body equivalent): 20µSv

Air Travel

  • Coast-to-coast US round trip flight: 120µSv

*Note:  Radiation dose of about 2,000 millisieverts (200,000 millirems) cause serious illness.

Half-life of some radioactive elements

[NOTE: Half-life is the time taken for a radioactive substance to decay by half.]

  • Cesium-134 ~ 2  years
  • Cesium-137 ~ 30 years
  • Iodine-131 ~ 8 days
  • Plutonium-239 ~ 24,200 years

The Following Announcements Was Released by TEPCO

News related to TEPCO (Sep 01,2013)
Explanation regarding the high radiation (maximum 1,800 mSv) found at tanks in Fukushima Daiichi NPS on August 31, 2013

We deeply apologize for the great anxiety and inconvenience caused by the recent contaminated water issues at the Fukushima Daiichi NPS, which affects the residents near the power station and the broader society.

Regarding the high radiation (maximum 1,800 mSv) found at tanks in Fukushima Daiichi NPS on August 31, some articles reported that “by simple calculation, if a person is exposed this much radiation amount for four hours continuously, that would lead to death” or “it takes only one minute to reach the annual radiation exposure limit for workers,” etc. We would like to explain more about the 1,800 mSv.

We used measuring equipment that measures both beta radiation and gamma radiation. The 1,800 mSv is the total amount of beta radiation and gamma radiation. Gamma radiation was 1 mSv and most of the 1,800 mSv was beta radiation.

Since 1,800 mSv is approximately 3.5 times higher than the control level of equivalent dose for skin which is 500 mSv/year, we should carefully control radiation exposure. Since beta radiation travels only a short distance, radiation level decreases considerably if we keep a distance. Moreover, since beta radiation is weak and can be blocked by a thin metal sheet such as aluminum, we think that we can control radiation exposure by using proper equipments and cloths.

Additionally, although 1,800 mSv was detected at 5 cm above the floor, the radiation level of 50 cm above the floor was 15 mSv. Thus, 1,800 mSv does not mean the radiation level of the whole nearby place.

Some articles reported that “if a person is exposed this much radiation amount for four hours continuously, that would lead to death” comparing with the radiation level that would result in death (7,000 mSv), or “it takes only one minute to reach the annual radiation exposure limit for workers” comparing with the annual radiation exposure limit for workers (50 mSv). However, we believe that simply comparing the 1,800 mSv with those standard levels is not proper, since the standard levels are accumulation of effective dose (not equivalent dose) that express effects for whole body.

We will find out the cause of this issue and make proper counter measures immediately, and continue to make every effort to secure safety of workers.

Japan’s Fukushima Nuke Plant Still Leaking

Posted by feww on June 28, 2011

Radioactive water leaking from Fukushima NPP

Some 15 tons of radioactive water have leaked from a storage tank at the stricken Fukushima NPP, Japan’s Nuclear and Industrial Safety Agency reported.

The plant operators, Tokyo Electric Power Company (TEPCO), continue to accumulate large volumes of radioactive contaminated water after being used to cool the melting reactors.

Meantime, TEPCO’s majority institutional shareholders have nixed a motion by a large number of individual shareholders to abandon nuclear energy in the wake of the Fukushima plant’s triple core meltdown.

Fukushima Radiation Leak NOT Fixed

Posted by feww on April 3, 2011

Japan Nuclear Disaster Update – April 3

Radioactive contaminated water still leaking into the ocean at a rate of about 2 liters per second: TEPCO

More than7 tons  of radioactive water is leaking into the ocean every hour, Tokyo Electric Company said, NHK reported.


A 20-cm crack at the bottom of a concrete duct near Reactor 2 at Fukushima NPP is releasing more than 7 tons or radioactive water into the ocean. Photo released by TEPCO.

Summary of Latest Developments:

  • Contaminated water in the duct is emitting more than 1,000 millisieverts per hour (100,000  millirems per hour)* of radiation into the surrounding environment.
  • Seawater samples taken 330 m south of the plants on March 31 contained both radioactive iodine-131 at 4,385 times and cesium-137 at 527 times above the legal limits. Cesium-137 has a half life of 30 years and persists much longer than iodine (half-life = 8 days, see also list below).
  • Workers made an unsuccessful attempt to plug the crack using concrete.
  • A second attempt made earlier today to fix the crack using a mixture of a chemical polymer, sawdust and shredded newspaper also failed.
  • TEPCO is preparing for a third attempt to plug the leak, using an absorbent gel which expands to contain water and is usually included in baby diapers and litter trays for pets.
  • About  164,000 people are currently living in shelters
  • At least 70,000 people have been evacuated from a 20 km exclusion zone of Fukushima NPP.
  • Up to  140,000 people live inside the next 10 km zone, who have been urged to leave or stay indoors.
  • “The impact of the nuclear crisis is expected to go on for a long time,”  Japan’s Chief Cabinet Secretary Yukio Edano said earlier today.

*Note:  Single radiation dose of 2,000 millisieverts (200,000 millirems) and above causes serious illness. See also exposure list below.

Japan’s Nuclear Crisis: Worst of its Triple Disasters

Posted by feww on March 27, 2011

Submitted by a reader, with additional materials added by FIRE-EARTH

Fukushima Nuclear Disaster, the Third of Japan’s Triple Disasters, Could Prove to Be its Worst

Potentially deadly levels of radiation have been detected in water at the earthquake-and-tsunami-stricken Fukushima NPP.

The amount of radioactive iodine detected in water at Reactor 2 was more than 1,000 millisieverts an hour, or 10 million times higher than when reactor operates normally, said the plant operator TEPCO.

The IAEA boss, Yukiya Amano, has warned that the nuclear crisis could continue for many weeks, even months. “This is a very serious accident by all standards,” NY Times quoted him as saying.

Radioactivity in seawater near the plant jumped to 1,850 times the normal up from 1,250 on Saturday, said Japan’s Nuclear and Industrial Safety Agency.

Fukushima Disaster: Will it Become Much Worse than Chernobyl?

The Chernobyl nuclear plant reactor was destroyed when two explosions blew away its roof exposing the core on April 26, 1986. A large plume of radioactive materials escaped into the atmosphere covering large regions in the former Soviet Union, Europe and across much of the Northern Hemisphere.


Ukrainian city of Chernobyl had managed to live for 793 years… that is until the Chernobyl nuclear power plant underwent a core meltdown on April 26, 1986 at about 1:00am local time. This image was taken by authorities in the former Soviet Union


Birth defects and cancer were the norm for many years following the Chernobyl disaster.  By the time  residents of Pripyat, a town located near the plant, were ordered to evacuate, about two days after the Chernobyl core meltdown had occurred, many had already been exposed to varying doses of radiation poisoning.

Fukushima NPP is said to contain about 4,277 tons of nuclear fuel, about 24 times as much as Chernobyl (~ 180 tons).

“The Fukushima Dai-ichi site has a considerable number of fuel rods on hand, according to information provided Thursday by Toyko Electric Power Co., which owns the atomic complex: There are 3,400 tons of fuel in seven spent fuel pools within the six-reactor plant, including one joint pool storing very old fuel from units 3 and 4. There are 877 tons in five of the reactor cores. Officials have said that the fuel in Unit 4’s reactor vessel was transferred to its spent fuel pool when the unit was temporarily shut in November.” AP reported.

The Incident: A meltdown of the reactor’s core in the Chernobyl power plant killed thirty people in 1986. About 135,000 people were evacuated. It is believed that about one hundred times more radiation was released in the accident than by the atom bombs dropped over Hiroshima and Nagasaki in 1945.

Legacy: More than 4000 cases of thyroid cancer were diagnosed among children and adolescents between 1992 to 2002 in Belarus, Russia and Ukraine. Victims under 14 years were most severely affected by the elevated concentrations of radioiodine found in milk.

Incidents of skin lesions, respiratory ailments, infertility and birth defects were readily found among the more than five million people who inhabit the affected areas of Belarus, Russia, and Ukraine for many years following the accident.

The Poisoned land. Up to 5 million people continue to live on radioactive contaminated land. About 85% of the children who live in contaminated areas of Belarus today are ill, a near 6-fold increase compared to the time before the explosion (15%), according to The Belarusian National Academy of Sciences.

Disputed Facts: The above facts, however, have been disputed by a number of individuals including the author of a recent WHO report, and the retired “nukophile” British academic, James Lovelack. Local and international experts, however, have dismissed the WHO report findings. A UN report released in 2005 estimated the number of victims at just 4,000. Their figure is hotly disputed  by NGOs and independent experts.

“A report by Alexey Yablokov, Vassily Nesterenko and Alexey Nesterenko which appeared in the Annals of the New York Academy of Science showed that by 2004, there were 985,000 additional deaths worldwide caused by the nuclear disaster, including 212,000 of them within Western Russia, Belarus and Ukraine.”

Chernobyl fallout covers the entire Northern Hemisphere

Consequences of the Catastrophe. Authors  Alexey Yablokov (Center for Russian Environmental Policy in Moscow), Vassily Nesterenko and Alexey Nesterenko ( Institute of Radiation Safety, Minsk, Belarus) studies about 5,000 reports and scientific  papers mostly published in Slavic languages and compiled their finding in the  book “Chernobyl: Consequences of the Catastrophe for People and the Environment,” which was published last year on the 24th anniversary of the Chernobyl reactor core meltdown.

“For the past 23 years, it has been clear that there is a danger greater than nuclear weapons concealed within nuclear power. Emissions from this one reactor exceeded a hundred-fold the radioactive contamination of the bombs dropped on Hiroshima and Nagasaki.” They wrote.

“No citizen of any country can be assured that he or she can be protected from radioactive contamination. One nuclear reactor can pollute half the globe,” the authors said. “Chernobyl fallout covers the entire Northern Hemisphere.”

According to the book, a total of about 830,000 people, referred to as the “liquidators,” were responsible for various emergency works at the Chernobyl site including fire extinguishing, decontamination and cleanup.

The authors say between 112,000 and 125,000 of the  liquidators had died by 2005.  The authors also estimate that between 1986 and 2004 some 985,000 people died as a result of Chernobyl fallout {2011 estimates are well over a million deaths.]

“Official discussions from the International Atomic Energy Agency and associated United Nations’ agencies (e.g. the Chernobyl Forum reports) have largely downplayed or ignored many of the findings reported in the Eastern European scientific literature and consequently have erred by not including these assessments.” The authors said last year.

Chernobyl and Other Nuclear Stats

  • More than 95% of the radioactive material (180 metric tons with a radioactivity of about 18 million curies) still remains inside the Chernobyl reactor.
  • The  core meltdown at Chernobyl was said to have released radiation estimated at 50 million curies. Committee on the Safety of Nuclear Installations said in 1995 that the meltdown had released about 140 million curies. [Researchers Alexey Yablokov, Vassily Nesterenko and Alexey Nesterenko say the radiation released from Chernobyl may have been up to 10 billion curies. In comparison, the Hiroshima bomb released about 3 million curies.]
  • Immediately after the accident, 237 people suffered from acute radiation sickness, and 31 died within the first 90 days of the disaster.
  • About 135,000 people were evacuated from the area surrounding the plant, including 50,000 from the town of Pripyat.
  • The Academy’s  estimate for the number of casualties  are more than 90,000 deaths and more than a quarter of a million cancer cases.
  • The Ukrainian National Commission for Radiation Protection calculates the number of radiation casualties at half a million  deaths so far.
  • In a book published by the New York Academy of Sciences last year on the 24th anniversary of the reactor core meltdown, the researchers maintain that about one million people have died from exposure to radiation released by the Chernobyl reactor so far [as of 2010.]
  • “In the former Soviet Union at least 9 million people have been effected by the accident; 2.5 million in Belarus; 3.5 million in Ukraine; and 3 million in Russia. In total over 160 000 Km2 are contaminated in the three republics.” source
  • Some 441 commercial nuclear power reactors are  operating in 31 countries ( total capacity of 376 gigawatts) each of which is potentially as lethal as Chernobyl, if not worse. [This item, updated here, was written before the Fukushima nuclear disaster began unfolding.]
  • An estimated 56 countries operate more than 250 research reactors.
  • At least 220 nuclear reactors power military ships and submarines.
