Just as with the Gulf oil spill – where BP, government spokesmen and mainstream talking heads spewed happy talk about how “benign” the dispersants were and how all the oil had disappeared – there is now an avalanche of statements that the radiation is at “safe” doses for everyone outside of the immediate vicinity of Fukushima.

For example, Japanese government call-in advice lines are telling people to simply rinse off any produce covered with radioactive dust.

Ann Coulter claims that radiation is good for you

It is not very confidence-inspiring that:

EPA officials, however, refused to answer questions or make staff members available to explain the exact location and number of monitors, or the levels of radiation, if any, being recorded at existing monitors in California.

Or that the EPA has pulled 8 of its 18 radiation monitors in California, Oregon and Washington because (by implication) they are giving readings which seem too high.

What Levels of Radiation Are Being Released?

So what levels of radiation are being released at Fukushima?

New Scientist reports that the radioactive fallout from Japan is approaching Chernobyl levels:

Japan’s damaged nuclear plant in Fukushima has been emitting radioactive iodine and caesium at levels approaching those seen in the aftermath of the Chernobyl accident in 1986. Austrian researchers have used a worldwide network of radiation detectors – designed to spot clandestine nuclear bomb tests – to show that iodine-131 is being released at daily levels 73 per cent of those seen after the 1986 disaster. The daily amount of caesium-137 released from Fukushima Daiichi is around 60 per cent of the amount released from Chernobyl.

Tyler Durden points out that – when you consider the fact that the amount of Caesium-137 released at Fukushima in the first 3-4 days of the crisis amounted to 50% that released by Chernobyl over 10 days – the real run rate of the radiation released at Fukushima is now about 120-150% the figure released by the Chernobyl explosion.

There are other signs of high levels radiation. See this and this. And it is important to remember that the amount of radioactive fuel at Fukushima dwarfs Chernobyl.

This Could Continue for a While

Many experts say that it could take months to contain Fukushima. See this and this. And therefore, high radiation levels might continue to be released for some time.

Evidence for the fact that a quick fix is unlikely is widespread. For example, reactors 1, 2, 3 and 4 were all leaking steam yesterday.

There was some indication that reactors 5 and 6 are leaking as well. As Kyodo News reports:

The firm [Tokyo Electric Power Company] also said it found both iodine-131 and cesium-137 in a sample taken from near the drain outlets of the plant’s No. 5 and No. 6 reactors that stabilized Sunday in so-called ”cold shutdown.”

CNN notes today:

Authorities in Japan raised the prospect Friday of a likely breach in the all-important containment vessel of the No. 3 reactor at the stricken Fukushima Daiichi nuclear power plant, a potentially ominous development in the race to prevent a large-scale release of radiation.

The New York Times reports:

A senior nuclear executive who insisted on anonymity but has broad contacts in Japan said that there was a long vertical crack running down the side of the reactor vessel itself. The crack runs down below the water level in the reactor and has been leaking fluids and gases, he said.***

“There is a definite, definite crack in the vessel — it’s up and down and it’s large,” he said. “The problem with cracks is they do not get smaller.”

The cores of reactors 1 and 3 appear to be leaking as well.

This is not to say that there will be a full meltdown which sends radioactive plumes high into the stratosphere. I am assuming that will not happen. But the release of radioactivity is severe and ongoing.

But Low Doses of Radiation Are Safe … Aren’t They?

While most would dismiss as crackpot ramblings Coulter’s claim that radiation is good for you, what about the pervasive claims that the amount of radiation which has been released is so low that it is “safe” for people outside of the immediate vicinity of Fukushima?

Physicians for Social Responsibility notes:

According to the National Academy of Sciences, there are no safe doses of radiation. Decades of research show clearly that any dose of radiation increases an individual’s risk for the development of cancer.

“There is no safe level of radionuclide exposure, whether from food, water or other sources. Period,” said Jeff Patterson, DO, immediate past president of Physicians for Social Responsibility. “Exposure to radionuclides, such as iodine-131 and cesium-137, increases the incidence of cancer. For this reason, every effort must be taken to minimize the radionuclide content in food and water.”

“Consuming food containing radionuclides is particularly dangerous. If an individual ingests or inhales a radioactive particle, it continues to irradiate the body as long as it remains radioactive and stays in the body,”said Alan H. Lockwood, MD, a member of the Board of Physicians for Social Responsibility.

***

Radiation can be concentrated many times in the food chain and any consumption adds to the cumulative risk of cancer and other diseases.

John LaForge notes:

The National Council on Radiation Protection says, “… every increment of radiation exposure produces an incremen­tal increase in the risk of cancer.” The Environmental Protection Agency says, “… any exposure to radiation poses some risk, i.e. there is no level below which we can say an exposure poses no risk.” The Department of Energy says about “low levels of radiation” that “… the major effect is a very slight increase in cancer risk.” The Nuclear Regulatory Commission says, “any amount of radiation may pose some risk for causing cancer … any increase in dose, no matter how small, results in an incremental increase in risk.” The National Academy of Sciences, in its “Biological Effects of Ionizing Radiation VII,” says, “… it is unlikely that a threshold exists for the induction of cancers ….”

Long story short, “One can no longer speak of a ‘safe’ dose level,” as Dr. Ian Fairlie and Dr. Marvin Resnikoff said in their report “No dose too low,” in the Bulletin of the Atomic Scientists.

And Brian Moench, MD, writes:

Administration spokespeople continuously claim “no threat” from the radiation reaching the US from Japan, just as they did with oil hemorrhaging into the Gulf. Perhaps we should all whistle “Don’t worry, be happy” in unison. A thorough review of the science, however, begs a second opinion.

That the radiation is being released 5,000 miles away isn’t as comforting as it seems…. Every day, the jet stream carries pollution from Asian smoke stacks and dust from the Gobi Desert to our West Coast, contributing 10 to 60 percent of the total pollution breathed by Californians, depending on the time of year. Mercury is probably the second most toxic substance known after plutonium. Half the mercury in the atmosphere over the entire US originates in China. It, too, is 5,000 miles away. A week after a nuclear weapons test in China, iodine 131 could be detected in the thyroid glands of deer in Colorado, although it could not be detected in the air or in nearby vegetation.
The idea that a threshold exists or there is a safe level of radiation for human exposure began unraveling in the 1950s when research showed one pelvic x-ray in a pregnant woman could double the rate of childhood leukemia in an exposed baby. Furthermore, the risk was ten times higher if it occurred in the first three months of pregnancy than near the end. This became the stepping-stone to the understanding that the timing of exposure was even more critical than the dose. The earlier in embryonic development it occurred, the greater the risk.

A new medical concept has emerged, increasingly supported by the latest research, called “fetal origins of disease,” that centers on the evidence that a multitude of chronic diseases, including cancer, often have their origins in the first few weeks after conception by environmental insults disturbing normal embryonic development. It is now established medical advice that pregnant women should avoid any exposure to x-rays, medicines or chemicals when not absolutely necessary, no matter how small the dose, especially in the first three months.

“Epigenetics” is a term integral to fetal origins of disease, referring to chemical attachments to genes that turn them on or off inappropriately and have impacts functionally similar to broken genetic bonds. Epigenetic changes can be caused by unimaginably small doses – parts per trillion – be it chemicals, air pollution, cigarette smoke or radiation. Furthermore, these epigenetic changes can occur within minutes after exposure and may be passed on to subsequent generations.

The Endocrine Society, 14,000 researchers and medical specialists in more than 100 countries, warned that “even infinitesimally low levels of exposure to endocrine-disrupting chemicals, indeed, any level of exposure at all, may cause endocrine or reproductive abnormalities, particularly if exposure occurs during a critical developmental window. Surprisingly, low doses may even exert more potent effects than higher doses.” If hormone-mimicking chemicals at any level are not safe for a fetus, then the concept is likely to be equally true of the even more intensely toxic radioactive elements drifting over from Japan, some of which may also act as endocrine disruptors.

Many epidemiologic studies show that extremely low doses of radiation increase the incidence of childhood cancers, low birth-weight babies, premature births, infant mortality, birth defects and even diminished intelligence. Just two abdominal x-rays delivered to a male can slightly increase the chance of his future children developing leukemia. By damaging proteins anywhere in a living cell, radiation can accelerate the aging process and diminish the function of any organ. Cells can repair themselves, but the rapidly growing cells in a fetus may divide before repair can occur, negating the body’s defense mechanism and replicating the damage.

Comforting statements about the safety of low radiation are not even accurate for adults. Small increases in risk per individual have immense consequences in the aggregate. When low risk is accepted for billions of people, there will still be millions of victims. New research on risks of x-rays illustrate the point.

Radiation from CT coronary scans is considered low, but, statistically, it causes cancer in one of every 270 40-year-old women who receive the scan. Twenty year olds will have double that rate. Annually, 29,000 cancers are caused by the 70 million CT scans done in the US. Common, low-dose dental x-rays more than double the rate of thyroid cancer. Those exposed to repeated dental x-rays have an even higher risk of thyroid cancer.

***

Beginning with Madam Curie, the story of nuclear power is one where key players have consistently miscalculated or misrepresented the risks of radiation. The victims include many of those who worked on the original Manhattan Project, the 200,000 soldiers who were assigned to eye witness our nuclear tests, the residents of the Western US who absorbed the lion’s share of fallout from our nuclear testing in Nevada, the thousands of forgotten victims of Three Mile Island or the likely hundreds of thousands of casualties of Chernobyl. This could be the latest chapter in that long and tragic story when, once again, we were told not to worry.

Note: People who rationally discuss the hazards from nuclear accidents are dismissed as “anti-nuclear”. However, that is like saying that people who are against pilots drinking tequila during flights are anti-flying. As Bloomberg points out, the operator of the Fukushima reactors faked safety tests and results and cut every corner in the books for decades, just as BP cut every safety corner prior to the Gulf oil spill. Moreover, the Fukushima reactors were not designed to withstand an earthquake or a tsunami, and their peculiar design makes the spent fuel rods an even greater danger than the reactors themselves.

Demanding a safer design – e.g. thorium reactors – and ongoing maintenance and safety tests doesn’t mean one is anti-nuclear.

    As for Ann Coulter, I’d like to see her build a condo atop any one of the six TEP reactors of her choice.

  2. [...] No, the Amount of Radiation Released from the Japanese Nuclear Reactors is NOT “Safe” (ritholtz.com) [...]

  3. cognos says:

    This is a poor post. It’s fear inducing. There seem to be far more credible experts who cite very low risks both to further escalation and current radiation levels. We rec radiation doses everyday and certain activiies like long jet flIghts subject one to 100x the normal radiation dose. Or a chest X-ray (much much higher).

    1) beware any article that dOes not COMPARE levels to normal experiences. This is fear mongering.

    2) beware any article that suggests thIs could be a global catastrophe. This is STUPID. We once dropped large atomic bombs directly on JApan. There have been thousands of nuclear bomb tests, including plutonium! We once dropped atomic bombs in Nevada and New Mexico. While not without long-term effects, like 1-5% increases In the frequency of certain cancers 30 yrs later. There can be no catastrophe.

    So much silly fear.

  4. cognos says:

    Remember, the news outlets love sensationalist fear. It keep ratings high.

    I guess that includes bloggers.

  5. Mark A. Sadowski says:

    This incident has exposed a major case of regulatory capture in Japan. TEPCO supplies power to a third of Japan and is responsible for all of the power in Tokyo. Over the past two weeks we have seen this situation turn out consistently worse than TEPCO and the Japanese government authorities have predicted. We have also seen the US NRA openly contradict the Japanese nuclear regulatory agency and WHO openly contradict the Japanese health authorities. And Japanese officials still are only ranking this disaster a 5 on the 7 point INES scale, the same level as Three Mile Island. (Give me a break!)

    Based on data collection by the Austrian Central Institute of Meteorology and Geodynamics (ZAMG) using the worldwide network of radiation detectors designed to spot clandestine nuclear bomb tests in order to monitor the compliance with the Comprehensive Test Ban Treaty (CTBT) it is now safe to conclude that in terms of the total amounts of iodine-131 and caesium-137 emitted this is already the worst nuclear energy disaster in history. As a consequence of that, and data collected by France’s radiation protection agency (IRSN), Dr Helmut Hirsch, in analysis prepared for Greenpeace, strongly recommends classifying this disaster as a 7 on the INES scale (in fact it is equivalent to three level 7 INES incidents):

    http://www.greenpeace.de/fileadmin/gpd/user_upload/themen/atomkraft/INES_7march_25th.pdf

    The emissions could go on for weeks or even months, and given that there is roughly six times as much fissionable material at Fukushima as at Chernobyl, and that the population density of Japan is over 20 times that of Belarus, this disaster has the potential to make Chernobyl look like child’s play in terms of the human and economic toll. This blog post, if anything, is gravely understating the potential severity of the situation.

  6. cognos,

    you are UFB..

    do us a favor, if you think this Post is ‘fear-mongering’, please, lay out, in fuller detail, the ‘rational case’..

    or, as good, disprove anything that Sadowski, above, posited..

    personally, I’d like to see it/either..

  7. buskila says:

    You can see the current radiation levels here: http://atmc.jp/ and they keep adding more sources. Another source for radiation levels in Tokyo is here: http://park30.wakwak.com/~weather/geiger_index.html (seems to be someone with a Geiger counter). Yet another one (updated hourly): http://ftp.jaist.ac.jp/pub/emergency/monitoring.tokyo-eiken.go.jp/report/report_table.do.html

    While I realize that getting pageviews is a top priority for a blogger (and more and more for mainstream media it seems) spreading FUD in this situation seems unethical to me.

    I am not claiming that everything is fine – the situation is extremely serious, but maybe you can check the facts first and instead of publishing a video with white stuff rising from the reactor you could publish the links to actual facts.

  8. cognos says:

    I did cite facts:

    It is a simple obvious fact that we dropped atomic bombs on Japan and in Nevada and New Mexico. It is a further simple obvious fact that around 1,000 live nuclear bomb tests have been conducted since 1944. It is a widely known fact that everyday experiences cause radiation exposure – sun shine, chest X-ray, long distance flight.

    Yet this complete NON expert (seems to lack common sense) quotes a guy saying, “no radiation level is safe”.

    Please exit. I feel pretty safe.

  9. cognos says:

    Statements like – “has the potential to make Chernobyl look like childsplay” – identify the writer as stupid and careless. The motvstion is fear, no facts, no numbers, no common sense. Idiots.

    Radiation levels in tue surrounding areas are tiny. Few people will receive more than a few chest x-rays of radiation from this event the numbers are easy to find, the math is somethIng like 1,000 hrs outdoor exposure at last weeks levels in most areas = 1 chest X-ray.

    Further, the obsessive monitoring across food, water, air, etc… Make it likely we are OVER stating concerns.

    But what was the about “childsplay”? It sounded so intelligent and rational?

  10. Mark A. Sadowski says:

    cognos,
    The radiation levels are proportional to the amount of fallout. The amount of fallout is expected to accumulate for weeks and perhaps months to come. The fallout has already exceeded that at Chernobyl.

    Chernobyl’s consequences are well documented. The area irradiated has a population density 20 times greater than Chernobyl. Cesium-137 has a halflife of 30 years.

    Would you like to get a chest X-Ray every month the rest of your life? (Assuming you live no more than 18 miles from Fukushima?)

  11. ES says:

    As for me, I have no problem with a healthy dose of fear where nuclear power is concerned. Nuclear power can be used safely but it doesn’t make it any less dangerous. Some people keep tigers as pets and in some cases these cuddly tighers have been known to eat their owners.

  12. Mark A. Sadowski says:

    cognos,
    You mentioned the fact that over 1,000 live nuclear bomb tests have been conducted since 1944.

    Check this one out:

    http://www.youtube.com/watch?v=fd1IFjBNNVo&NR=1

    The single 15 Megaton bomb US test at Castle Bravo on March 1, 1954 is responsible for approximately 20% of all the above normal radiation in the atmosphere on earth until this day.

    P.S. There is no known safe level of radiation. Sweet dreams.

  13. cognos says:

    Mark -

    But everyone is evacuated “18 miles from Fukushima”? This is the huge KEY difference btw Fuku and Chernobyl. Not understanding this is being a silly impractical person.

    Do you feel safe getting a chest xRay? Do you feel safe from radiation flying a long distance flight? MANY levels of radiation exposure are safe.

    Why do you continue to make stupid statements?

    Very few Japanese people will receive more than 2 chest xRay worth of radiation due to Fukushima. Zero people outside Japan will receive more than 0.1 chest xRays worth in their lifetimes. Yet bc of stupidity like this… people are buying potassium iodide in Kansas.

    BTW… the average CT scan gives as much radiation as 400 (!!!) chest xRays… the average mammogram 20x as much as a chest xRay. Are these safe? Why do we do CT scans if subject one to 100x the radiation of this Fukushima thing for Tokyo citizens? Uh… because its safe.

    Seriously… time to end the stupidity.

  14. cognos says:

    Everybody here seems to love a good witch hunt.

    Bankers… nuclear power plants… European soverign borrowers… they’re evil… lets get ‘em and punish ‘em.

    Ignorance and fear have been driving human group behavior for thousands of years.

  15. victor says:

    Hey cognos, you’re right. Add to the evil list the oil companies (never mind that ever since the role of the Railroad Commission of Texas was effectively replaced by OPEC they have become price takers not price makers). But without a dragon to sleigh who could sell any thing in the news media today? My instincts tell me that this too shall pass, Japan will re-build (36 months?) but she’ll be a bit poorer because of this tragedy. As to what’s safe and what is not safe, looks like we’ll have to wait and see, lucky all those of us who do not live/work in the area affected.
