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
  • Ruthenium-103 ~ 39 days [Ruthenium is a fission product of uranium-235.]
  • Ruthenium-106 ~ 374 days
  • Strontium-90 ~ 28.85 years  [Strontium-90 is a product of nuclear fission and is found in large amounts in spent nuclear fuel and in radioactive waste from nuclear reactors.]
  • Uranium-234 ~  246,000 years
  • Uranium-235 ~ 703.8  million years
  • Uranium-238  ~ 4.468 billion 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.

Radiation Record Broken by Fukushima Fish

Posted by feww on March 18, 2013

Fish found with record 7,400 times the legal radiation limit near Fukushima NPP

The Operators of Fukushima Daiichi Nuclear Power Station, Tokyo Electric Power Co (TEPCO), said they had caught a fish with record 740,000 becquerels per kilogram of radioactive cesium, Kyodo News reported.

The radiated fish, a greenling, which measured 38 cm long and weighed 564 grams, was caught near a water intake of the power station on February 21, said the report.

The previous known record of radioactive cesium contamination in fish was 510,000 becquerels per kilogram found in another greenling caught in the same area…

The Fukushima Daiichi nuclear plant underwent multiple meltdowns after it was crippled by the Great Eastern Japan Earthquake and the ensuing tsunami on March 11, 2011.

Record High Radiation Found in Fukushima Fish

Posted by feww on March 1, 2013

Contaminated fish caught near Japan’s Fukushima Daiichi NPP had 5,100 times the legal radiation limits: TEPCO

The hexagrammos otakii  (Fat Greening, Ainame) fish, caught in a port near the nuclear power plant, showed caesium contamination reaching 510,000 becquerels per kilogram, or 5,100 times more than the government food limit, said the Tokyo Electric Power Company (TEPCO).

The latest find is more than twice the previous record caesium contamination in fish of 254,000 becquerels per kilogram.

Meantime, caesium radiation equivalent to 277,000 becquerels per kilogram were also found in a rockfish, said the company.
