Fukushima radiation levels underestimated by five times - TEPCO


TEPCO has revised the readings on the radioactivity levels at the Fukushima No. 1 nuclear plant well to 5 million becquerels of strontium per liter – both a record, and nearly five times higher than the original reading of 900,000 becquerels per liter.

But is that a significant level? Radiation exposure depends on distance. Distance squared actually. At twice the distance you are from a source you get one fourth of the exposure. At four times the distance, you get one sixteenth the exposure.

If my car was travelling at two miles an hour and suddenly is racing at five times the speed am I in a dangerous situation (at ten miles per hour)?
How fast were we driving when the car sped up?

Hmm, Zippy or Michio Kaku? I'd put my money on Michio.

Navy Tech v a recognized Theoretical Physicist.

Yeah,, I can't wait to hear how harmless Strontium 90 is.


http://en.wikipedia.org/wiki/Strontium-90

Strontium-90 is a "bone seeker" that exhibits biochemical behavior similar to calcium, the next lighter group 2 element. After entering the organism, most often by ingestion with contaminated food or water, about 70–80% of the dose gets excreted. Virtually all remaining strontium-90 is deposited in bones and bone marrow, with the remaining 1% remaining in blood and soft tissues. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. Exposure to 90Sr can be tested by a bioassay, most commonly by urinalysis. Strontium-90 is probably the most dangerous component of the radioactive fallout from a nuclear weapon.

You do realize that Theoretical Physics isn't Nuclear Science, right? And that video is from 2011, so.....

I realize both..

But the thread caused me to look at what is new today.

Which is why I posted the links. This is NOT 3 years old.


The bulk of the radiation measurements taken at the crippled Fukushima No. 1 power plant since March 2011 will be reviewed because they were taken improperly and are probably too low, Tokyo Electric Power Co. revealed.

“We are very sorry, but we found cases in which beta radiation readings turned out to be wrong when the radioactivity concentration of a sample was high,” Tepco spokesman Masayuki Ono told a news conference Friday. Materials known to emit beta rays include strontium-90, which causes bone cancer.

The announcement follows Tepco’s finding Thursday that a groundwater sample it had taken from a well at the No. 1 plant last July contained a record-high 5 million becquerels of strontium-90 per liter instead of 900,000 becquerels.


Among the data that need to be examined are the readings for around 300 tons of water that inexplicably vanished from a storage tank in August last year. Tepco had detected 80 million becquerels per liter of beta radiation from the leak, part of which is believed to have ended up in the Pacific.

Now please,,, put a happy spin on that. :(

[XNavyNuke]

But is that a significant level?

No, it's not. 5 million becquerels is roughly equivalent to 0.0001 curies. If you were to evaporate the liter of water to the single speck of remaining insoluble material ( to prevent self shielding by the mass of the water ), and place that speck at arms length from you, it would take 4.5 million hours of exposure to reach the LD50 level. Unrealistic, because your body is repairing the damage as its happening so LD never really applies, so you would have to magically compress five hundred years do to one hour the really get an LD.

Reporters love using becquerels because they get to throw around the words "millions", "billions", and "trillions" because they are much scarier than saying "one-thousandths" of anything. The only time highly educated journalism majors are unimpressed with the idea of "tens of trillions" is when it is followed by the negating words - "federal debt".

You seem to have me confused with someone else. I've never said that radiation is harmless. I have endeavored to put perspective on reported numbers that the media elites have chosen not to do. I have explained how amateur science, when conducted poorly and reported on in an uncritical manner, can be misleading. I keep bees. I would never say that they are not venomous insects, however I would take the time to point out the difference if someone claimed that a femtogram of their venom is as dangerous as a microgram. Fear steeped with ignorance has passed a lot of stupid rules around this country.

[pcosmar]

XNN

So,,
Exactly what level of Strontium 90 do you consider safe?

It is reported that "The legal standard for strontium emissions is 30 becquerels per liter."

OH,, and also,, This is in ground water,, not a storage tank.. A Ground water well located 25 meters from the Pacific ocean.

And again,, what lever of Strontium 90 is Safe?

I would say NONE.

I don't now squat about nuclear science. When XNN tells me to panic, though, I will.

I am not a Nuclear Physicist either.. But I am not entirely ignorant either.

I am fortunate to be highly resistant and am a walking talking MSDA violation. I am saturated with a number of things that are not good for anyone. I can breath in atmospheres that would kill most folks,, but I don't pretend that it is good for anyone.

I am also not opposed to capitalism,, But I am opposed to blind heartless greed.

This is a major disaster,, and no amount of spin will change that. The Nuclear testing of the 50s still has wide ranging deleterious effects.
This Preventable disaster will have wide ranging effects,, for many years to come.

The waters of the Pacific will dilute the radiation levels.

[Acala]

Isn't this the guy who said North America would need to be evacuated and then retracted his own statement on the grounds that it was ridiculous?

[pcosmar]

The waters of the Pacific will dilute the radiation levels.

You say diluted. I say spread.

http://en.wikipedia.org/wiki/Baby_Tooth_Survey

Preliminary results published by the team in the November 24, 1961, edition of the journal Science showed that levels of strontium 90 in children had risen steadily in children born in the 1950s, with those born later showing the most increased levels.[2] The results of a more comprehensive study of the elements found in the teeth collected showed that children born after 1963 had levels of strontium 90 in their baby teeth that was 50 times higher than that found in children born before the advent of large-scale atomic testing. The findings helped convince U.S. President John F. Kennedy to sign the Partial Nuclear Test Ban Treaty with the United Kingdom and Soviet Union, which ended the above-ground nuclear weapons testing that placed the greatest amounts of nuclear fallout into the atmosphere.


A set of 85,000 teeth that had been uncovered in storage in 2001 by Washington University were given to the Radiation and Public Health Project. By tracking 3,000 individuals who had participated in the tooth-collection project, the RHPR published results in a 2010 issue of the International Journal of Health Service that showed that the 12 children who later died of cancer before the age of 50 had levels of strontium 90 in their stored baby teeth that was twice the level of those who were still alive at 50.

[XNavyNuke]

So,,
Exactly what level of Strontium 90 do you consider safe?

My personal limit is 5000 millicuries per year, isotope non-specific, whole body.


It is reported that "The legal standard for strontium emissions is 30 becquerels per liter."

That must be for Japan. The EPA limit for potable water is 0.3 becquerels/liter for the public. NRC places the occupational ingestion limit at one million becquerels per year.

YMMV. If you are trying to achieve zero radiation dose I wish you luck with that.

Not necessarily zero. I do enjoy sunshine.
But there is no doubt in my mind that Nuclear testing and several serious accidents have contaminated this planet and contributed to the rise in Cancers.
And it is my personal view that the current levels of radiation are far more dangerous than my Cigarettes.

Oh.. and I do expect more. But I also expect to see "acceptable" levels to be raised accordingly.
