Fukushima Update: Why We Should (Still) Be Worried

After the catastrophic trifecta of the triple meltdowns at the Fukushima Daiichi nuclear complex in Japan last March—what the Japanese are referring to as their 3/11—you would think the Japanese government would be doing everything in its power to contain the disaster. You would be wrong—dead wrong.

Instead of collecting, isolating, and guarding the millions of tons of radioactive rubble that resulted from the chain reaction of the 9.0 earthquake, the subsequent 45- to 50-foot wall of water that swamped the plant and disabled the cooling systems for the reactors, and the ensuing meltdowns, Japanese Environment Minister Goshi Hosono says that the entire country must share Fukushima’s plight by accepting debris from the disaster.

The tsunami left an estimated 20 million tons of wreckage on the land, much of which—now ten months after the start of the disaster—is festering in stinking piles throughout the stricken region. (Up to 20 million more tons of rubble from the disaster—estimated to cover an area approximately the size of California—is also circulating in the Pacific.) The enormous volume of waste is much more than the disaster areas can handle. So, in an apparent attempt to return this region to some semblance of normal life, the plan is to spread out the waste to as many communities across the country as will take it.

At the end of September, Tokyo signed an agreement to accept 500,000 metric tons of rubble from Iwate Prefecture, one of eight prefectures designated for cleanup under a new nuclear decontamination law passed on January 1. The law allows for much of the radioactively contaminated rubble to be incinerated, a practice that has been underway at least since the end of June.

But the sheer amount of radioactive rubble is proving difficult to process. The municipal government of Kashiwa, in Chiba Prefecture to the west and south of Tokyo, recently shut down one of its main incinerators, because it can’t store any more than the 200 metric tons of radioactive ash it already has that is too contaminated to bury in a landfill.

According to the California-based Fukushima Fallout Awareness Network (FFAN), burning Fukushima’s radioactive rubble is the worst possible way to deal with the problem. That’s because incinerating it releases much more radioactivity into the air, not only magnifying the contamination all over Japan but also sending it up into the jet stream. Once in the jet stream, the radioactive particles travel across the Northern Hemisphere, coming back down to earth with rain, snow, or other precipitation. Five days after the Fukushima meltdowns began, radioactive fallout from the disaster reached the West Coast of the United States. Approximately a week later, Fukushima fallout was measured as far away as France.

In October, the journal Nature reported that the Japanese government’s initial estimates of radiation from Fukushima were substantially less than what Scandinavian researchers calculated from a global network of radiation monitoring stations that the Vienna-based Comprehensive Nuclear-Test-Ban Treaty Organization uses to detect nuclear weapons tests.

Radiation used to be a word that evoked serious concern in a lot of people. However, the nuclear industry and its supporters have done a masterful job in allaying public fears about it. They do this in significant part by relying on outdated and highly questionable data collected on Japanese atom bomb survivors, while at the same time ignoring and dismissing inconvenient but much more relevant evidence that shows the actual harmful effects of radiation exposure from nuclear accidents. Author Gayle Greene explains this well in a recent article here. In their attempt to win the public over to their viewpoint, nuclear proponents even trot out the dubious theory of radiation hormesis, which says that low doses of radiation are actually good for you, because they stimulate an immune response. Well, so does something that causes an allergic reaction. But I digress…

What Radiation Is

A great help to nuclear proponents is the fact that nuclear physics is complicated, and most people don’t understand even its most basic concepts. The blanket term “radiation” is used to describe all manner of radioactive contamination—as if it’s just one thing—when, in fact, there are different kinds, some much more damaging than others. It also matters exactly what is being exposed to radiation—i.e., exposure outside the body or inside it—and how long the exposure goes on.

In a nutshell, radioactive elements, also known as radioisotopes or radionuclides, are unstable atoms. They seek stability by giving off particles and energy—ionizing radiation—until the radioisotope becomes stable. This process occurs within the nucleus of the radioisotope, and the shedding of these particles and energy is commonly referred to as ‘‘nuclear disintegration.’’ Nuclear radiation expert Rosalie Bertell describes the release of energy in each disintegration as ‘‘an explosion on the microscopic level.”

This process is known as the “decay chain,” and during their decay, most radioactive elements morph into yet other radioactive elements on their journey to becoming lighter, stable atoms at the end of the chain. Some of the morphed-into elements are much more dangerous than the original radioisotope, and the decay chain can take a very long time. This is the reason that radioactive contamination can last so long.

To further complicate the issue, different radioisotopes give off different kinds of radiation—alpha, beta, gamma, X ray, or neutron emissions—all of which behave differently. Alpha emitters, such as plutonium and radon, are intensely ionizing but don’t penetrate very far and generally can’t get through the dead layers of cells covering skin. But when they are inhaled from the air or ingested from radiation-contaminated food or water, they emit high-energy particles that can do serious damage to the cells of sensitive internal soft tissues and organs. The lighter, faster-moving beta particles can penetrate far more deeply than alpha particles, though sheets of metal and heavy clothing can block them. Beta particles are also very dangerous when inhaled or ingested. Strontium-90 and tritium, a radioactive form of hydrogen, are both beta emitters. Gamma radiation is a form of electromagnetic energy like X rays, and it passes through clothing and skin straight into the body. A one-inch shield of either lead or iron, or eight inches of concrete are needed to stop gamma rays, examples of which include cobalt-60 and cesium-137—one of the radionuclides of most concern in the Fukushima fallout. Aside from use in medical diagnostics, X rays are also produced in nuclear fission, and their effects are similar to gamma radiation. Neutron emissions are the most penetrating of all types of radiation and require a shield of several feet of water or concrete to contain them.

The behavior of radioisotopes out in the environment also varies depending on what they encounter. They can combine with one another or with stable chemicals to form molecules that may or may not dissolve in water. They can combine with solids, liquids, or gases at ordinary temperature and pressure. They may be able to enter into biochemical reactions, or they may be biologically inert.

In her book No Immediate Danger: Prognosis for a Radioactive Earth, Bertell notes that if they enter the body either through air, food, water, or an open wound, “They may remain near the place of entry into the body or travel in the bloodstream or lymph fluid. They can be incorporated into the tissue or bone. They may remain in the body for minutes or hours or a lifetime.” To illustrate how different radioisotopes behave, she points out that: “Plutonium is biologically and chemically attracted to bone as is the naturally occurring radioactive chemical radium. However, plutonium clumps on the surface of bone, delivering a concentrated dose of alpha radiation to surrounding cells, whereas radium diffuses homogeneously in bone and thus has a lesser localized cell damage effect. This makes plutonium, because of the concentration, much more biologically toxic than a comparable amount of radium.”

Specific health effects from internal radiation exposure correlate with where radioisotopes land in the body. Bertell explains: “For example, radionuclides lodged in the bones can damage bone marrow and cause bone cancers or leukemia, while radionuclides lodged in the lungs can cause respiratory diseases. Generalized whole body exposure to radiation can be expressed as a stress related to a person’s hereditary medical weakness. Individual breakdown usually occurs at our weakest point.” In other words, the impact of radiation exposure also depends very much on each individual’s level of health and genetic make-up.

Fukushima’s Unending Fallout

Fetuses in utero, infants, and young children—all of whom have quickly dividing cells—as well as the elderly and people with compromised immune systems are most vulnerable to radiation exposure. “Official” sources like the Environmental Protection Agency and the UC Berkeley Nuclear Engineering Air Monitoring Station consistently downplay the health effects of the fallout. In fact, the EPA was so confident that Fukushima fallout would not be a problem for U.S. citizens that it stopped its specific monitoring of fallout from Fukushima less than two months after the meltdowns began.

But neglecting to monitor the fallout will not make it go away. In fact, another enormous problem with radioactive contamination is that it bioaccumulates in the environment, which means it concentrates as it moves up the food chain. (Think of mercury in fish.) Because many radionuclides are so long-lived, this can be a problem for a very long time. For example, the U.K. is only now considering lifting restrictions on the remaining 334 sheep farms in Wales that are still prohibited from selling any meat because of contamination from the Chernobyl disaster in April 1986.

In this video, FFAN member Kimberly Roberson points out that the first disaster at Fukushima Daiichi following the earthquake and tsunami was accidental: “However, by burning the millions of tons of radioactive rubble, it’s going to provide a brand new humanitarian crisis.” She observes that this crisis—“transgenerational DNA damage that’s passed well into the future”—is additional and intentional, and that everything possible must be done to stop it.

Roberson’s point is well taken. However, the desperate yearning among the Japanese to get past this disaster combined with the uncharted territory of dealing with a triple-whammy catastrophe of this magnitude—earthquake, tsunami, and three nuclear meltdowns—seems to be clouding their vision. The truth is, a nuclear disaster offers no easy or good choices. But some, like vaporizing the radionuclides throughout the atmosphere, will unnecessarily prolong the danger to the people and environment of Japan and spread the pain far and wide.

    Why do they call it “fall-out”?  because nobody cares about it until their hair and teeth start falling out…

    People in the Western World, need to reexamine the “way” they view Japan and that includes not only how that Country is governed but what actual “say” the Japanese people have in their Governments process!

    It has taken almost a year to realize that Japan is actually being “run” by its Powerful Utility Companies and this “business” relationship extends in a “Control Continuum” that extends at one end, from actual Utility direct financial support of the highest Government Leaders in the Country, to the widely known use of organized gangs to keep citizens in line at the other!

    The idea that individual Japanese people actually have a say in how they are governed, much less the way their Energy is generated, is just a well publicized fantasy that the Utilities uses to put a nuclear “smily face” on the grim reality that  ever facet of Japanese life is less important than what is good for these Utilities!  These Powerful Utilities ARE Japan, and the Japanese people are only “forced” customers of these Utilities since they have no other choice of providers when it come to basic needs like electricity, at  lest until now!  Solar panels have allowed many to get the electricity they need and this is a huge threat to these Utilities, that must be “crushed” ASAP if they are to maintain their complete control over the Japanese people!

    Ever since 3/11, the rest of the World’s attention has been focused on the Trillion Dollar Eco-Disaster at Fukushima and Japan’s response to their triple melt down.  What we have learned is that the Government has allowed TEPCO to not only remain in Control of this debacle but they have actually enabled the Utility to place huge numbers of Japanese citizens at risk rather than demand that the Utility think first of human health instead of Corp. shareholder profits.  The fact that radioactive pollution has now spread Globally and is affecting the rest of the Planet is hardly mentioned in MSM which points to an even greater problem for the rest of mankind; we are helpless and as yet unable to demand any “better” treatment from Japan because our own Leaders are for the most part are in full support of the those Utility backed Leaders in Japan.

    Kudos to Germany and many other Countries for pointing the finger at Nuclear Power and the Trillion Dollar Eco-Disaster RISK every nuclear complex now represents!  People globally now are becoming informed and starting to demand answers to basic questions and once people start asking questions perhaps change will occur, even if not for the Japanese themselves…  one thing is for certain, the Japanese people will be affected by their Trillion Dollar Eco-Disaster for much longer than the estimated 40 to 100 years that it will take to “tidy up” after Fukushima…

    The folks that I talk with seem numb. Fukushima gets a “yeah” and a nod. Maybe a “it’s bad.” 

    I live thirty miles from Plant Hatch in South GA. Tritium was found leaking into a well under the facility.  The five sentence announcement of that fact in the local paper didn’t generate so much as a yawn.  When officials were asked if the Tritium might leek into the underground water supply the probably not response stood. 

    But, then Vinod Khosla’s  Range Fuels defunct ethanol plant, now owned by LanzaTech, didn’t generate even an article in the local paper. 

    The plant that was supposed to be the clean and wonderful bright future for GA,  by way of  burned trees to ethanol, spent three years and well over $150 million, to include $6 million in Ga. tax money, on its way to being purchased on the  courthouse steps by LanzaTech for $5 million.  
    Talk about a sweet deal. Local response. Zip.

    Where did the $5 million go you ask. To help defray the  $40 million lost by the AgDept’s $80 million dollar loan guarantee. 

    P.S. The DOE lost $40 million of its $75 million grant. Ethanol? What ethanol. Technical difficulties were sited as the problem. That and the insight shared by a former CEO of Range Fuels. ” No one has figured out how to do it commercially yet.” Naw.

    I think folks are worn out with this.  Every day brings a new trauma of some kind. They are in survival mode. It won’t work. We gotta stay in the game.

    “They” aren’t going to take care of it. “They” will take advantage of it.

  • Kimroberson

    Curtis makes a very good point.  I’m sorry to hear of the situation in your community, it does seem like a struggle for survival all around. The issue that Ms. Charman so eloquently outlined brings something sinister very close to home.  The radioisotopes she wrote about cause DNA damage not only to us but to our children’s children..I’ve been talking endlessly about this since the end of March. 

    Cesium 137 with a half life of 30 years and a hazardous life for thousands more has been found in our food supply in CA (the major grower for much of US produce and dairy).  This is well documented by Univ. of Ca. Berkeley School of Nuclear Engineering (UCBSNE) on their website. Which essentially proves that radioisotope by products of nuclear power are now in US kitchens ..recent early Jan. sample tested positive for cesium again..YOUNG CHILDREN ARE UNSUSPECTEDLY DRINKING MILK WITH CESIUM AND STRONTIUM>>WHICH CAUSE CANCER.  Strontium is attracted to the bones and absorbed much like calcium. 

    I’m w/FFAN, quoted in the Ms. Charman’s piece and also in the video linked to it.  We issued a press release on the day of the anti incineration event which is featured in the video.  Sent it to Center for Investigative Reporting in Berkeley, the AP wire, spoke in detail and sent several links to both reporters, and several others..working this non stop with a group of dedicated experts and parents since Spring (shortly after when I started the petition posted earlier).. we did get a cameraman out to the event (a friend of a friend situation) so there was a 30 second blurb that night on one Bay Area news channel about the incineration and also that cesium 137 has been detected consistently now in CA topsoil, but that is mostly it for TV, and nothing of the event in print media until now unless I’m forgetting something..safe to say nothing in the mainstream media. Steve Hoffman and a few others have been blogging about it, thankfully.

    FFAN has had several meetings w/US Senators Barbara Boxer and Dianne Feinstein’s staff in SF and DC..at one point telling Feinstein face to face of the UCBSNE findings, followed by a footnoted letter sent as requested by her to her ‘personal and confidential’ fax …there is a STORY here!~ Ms. Charman told a huge piece of it which has restored a bit of my faith in journalism in this country.  FFAN is comprised of Nuclear Information and Resource Service, Beyond Nuclear, Ecological Options Network, Citizens for Health, and more.  We have a virtual clearinghouse of information and resources on the issue.

    Good piece, Karen Charman. This is a chilling scenario. If the UK is considering lifting restrictions on sheep farms in Wales because of contamination from the Chernobyl nuclear disaster 26 years ago, it’s probably too soon, even. But just think of the effects on our food supplies, not to mention air and water, should such a catastrophe befall one of the numerous 38+-year-old nuke power plants in the USA . . .
