Fukushima

Study: Fukushima Radiation Has Already Killed 14,000 Americans




23 May, 2013


A new study published in the peer-reviewed journal International Journal of Health Services alleges that 14,000 people have already died in the United States due to Fukushima.

Specifically, the authors of the study claim:

An estimated 14,000 excess deaths in the United States are linked to the radioactive fallout from the disaster at the Fukushima nuclear reactors in Japan, according to a major new article in the December 2011 edition of the International Journal of Health Services. This is the first peer-reviewed study published in a medical journal documenting the health hazards of Fukushima

.[The authors] note that their estimate of 14,000 excess U.S. deaths in the 14 weeks after the Fukushima meltdowns is comparable to the 16,500 excess deaths in the 17 weeks after the Chernobyl meltdown in 1986. The rise in reported deaths after Fukushima was largest among U.S. infants under age one. The 2010-2011 increase for infant deaths in the spring was 1.8 percent, compared to a decrease of 8.37 percent in the preceding 14 weeks.

The authors seem – at first glance – to have pretty solid credentials. Janette Sherman, M.D. worked for the Atomic Energy Commission (forerunner of the Nuclear Regulatory Commission) at the University of California in Berkeley, and for the U.S. Navy Radiation Defense Laboratory in San Francisco. She served on the EPA’s advisory board for 6 years, and has been an advisor to the National Cancer Institute on breast cancer. Dr. Sherman specializes in internal medicine and toxicology with an emphasis on chemicals and nuclear radiation.

Joseph J. Mangano is a public health administrator and researcher who has studied the connection between low-dose radiation exposure and subsequent risk of diseases such as cancer and damage to newborns. He has published numerous articles and letters in medical and other journals in addition to books, including Low Level Radiation and Immune System Disorders: An Atomic Era Legacy.

Sherman also claims that a study in British Columbia of infants under 1 year of age allegedly corroborates the increased deaths due to Fukushima:

But a Scientific American blog post and Med Page Today slam the study as being voodoo science. However, Scientific American does admit:


Certainly radiation from Fukushima is dangerous, and could very well lead to negative health effects—even across the Pacific.

What Do Other Experts Say?
Pediatrician Helen Caldicott said recently:
May I say that North America has received quite a large fallout itself.
***
We’re going to see an incredible increase in cancer, leukemia, and — down the time track — genetic disease. Not just in Japan but in the Northern Hemisphere, particularly North America.

Caldicott also wrote in a New York Times Op-Ed:

Children are innately sensitive to the carcinogenic effects of radiation, fetuses even more so. Like Chernobyl, the accident at Fukushima is of global proportions. Unusual levels of radiation have been discovered in British Columbia, along the West Coast and East Coast of the United States and in Europe, and heavy contamination has been found in oceanic waters.

Nuclear engineer Gunderson says that the Japanese will suffer one million cancer deaths from Fukushima, and that we’ll see a statistically meaningful increase in cancer on the West Coast of America and Canada from Fukushima. Gundersen says that – after Japan – the most radioactive areas are the Cascades and Portland.

There is certainly evidence that West Coast residents – especially in Seattle, Portland and other areas near the Cascades – have been hit with some radiation. And there is certainly evidence that radioactive contamination has spread in the United States, and will continue to spread for some time to come.
Why Is The Science So Hotly Debated?

Why is there so much dispute about the number of deaths which Fukushima could cause on the West Coast?

However – in the real world – radiation affects small children much more than full-grown adults. And small particles of radiation – called “internal emitters” – which get inside the body are much more dangerous than general exposures to radiation. See this and this.

In addition, American and Canadian authorities have virtually stopped monitoring airborn radiation, and are not testing fish for radiation. (Indeed, the EPA reacted to Fukushima by raising “acceptable” radiation levels.)

So – as in Japan – radiation is usually discovered by citizens and the handful of research scientists with funding to check, and not the government. See this, this, this, this, this and this.

The Japanese government’s entire strategy from day one has been to cover up the severity of the Fukushima accident. This has likely led to unnecessary, additional deaths.

So the failure of the American, Canadian and other governments to test for and share results is making it difficult to hold an open scientific debate about what is happening.

Fukushima No. 1 can’t keep its head above tainted water



21 May, 2013



Tokyo Electric Power Co. must decommission the three reactors, but the water is thwarting the effort. The decommissioning, if it ever starts, will take decades.
Here are some questions and answers on the encroaching problem and its implications for public health and the environment:
Why is radioactive water accumulating and how much is there?
As of May 7, Tepco had routed 290,000 tons of radioactive water into some 940 huge tanks at the complex, but 94,500 tons remain inside the basement floors of the reactor buildings and other facilities.
Tepco must perpetually pour water over the melted cores of reactors 1, 2, and 3 via makeshift systems to prevent the fuel from melting and burning again.
But the cores’ containment vessels were damaged by the meltdowns, allowing the highly radioactive coolant water to leak and flow into the basements. The dangerous radiation levels have prevented workers from getting close enough to fully assess the damage, let alone start the decommissioning process.
Compounding the problem is some 400 tons of groundwater that is also entering the basements of the tsunami- and explosion-damaged buildings, mixing with the leaking coolant water.
Tepco has been operating a water-recycling system to drain the basements that is supposed to extract cesium before recirculating the water back to the reactors. But the added inflow of the groundwater is exacerbating the threat.
In response, all Tepco has been able to do is build more storage tanks.
What problems will the water eventually pose?
Tepco says there is a limit to how many tanks the complex can accommodate before the site runs out of storage space.
Tepco said it can boost storage capacity from 430,000 tons from this year to 700,000 tons by mid-2015 by clearing a forest and other space in the compound. The move is expected to buy them about three years’ time.
Tepco is proposing some of the water be dumped into the sea after processing it to remove most, but not all, radioactive isotopes. Local fishermen strongly oppose the plan as it will taint the image of their produce.
Previous discharges into the Pacific have effectively contaminated the sea. Failure to store it means it will probably flood the whole compound and end up in the ocean anyway.
Neither Tepco nor government experts have come up with any other viable solutions.
Will the processed water pose health or environmental risks?
According to Tepco, the processed water could theoretically be safe, but fishermen and consumers disagree.
Tepco has been using an advanced liquid processing system made by Toshiba Corp. to decontaminate the coolant water.
ALPS can bring the density of 62 main radioactive substances below detectable levels, including strontium and plutonium.
Tritium is the exception, however. Tepco says the tritium level in the contaminated water is between 1 million and 5 million becquerels per liter. The legal limit is 60,000.
Tepco thus wants to dilute the water to bring the tritium density below the legal limit by dumping it into the sea. It has promised not to dump any without gaining the nod of local fishermen first.
Tritium, a common hazard at nuclear plants, can increase the risk of cancer if ingested and has a half life of 12.3 years. It is about 1,000th as radioactive as cesium-134 and -137.
Are there other concerns over water-related facilities?
Tepco revealed on April 5 that radioactive water stored in makeshift cisterns with coamings and surface covers were leaking into the soil.
This forced the utility to stop using the reservoirs, which were basically lined trenches with lids, and pump some 24,000 tons of tainted water out of them and into aboveground tanks.
The transfer is expected to be finished later this month.
Experts also are worried about the integrity of the 940 aboveground tanks built as of April 1, since 280 of them are considered “temporary” because they can only be used for up to five years. These are made of steel plates bolted together with waterproof packing to seal the seams, unlike welded steel tanks that offer a longer-term solution.
Tepco will need to start repairing or replacing the temporary tanks in spring 2016.
Tepco has dug 12 wells to intercept groundwater before it seeps into the reactor building basements. Will this work?
Yes, but only to a certain extent.
The wells were dug on the mountainside above the damaged buildings. Tepco plans to pump up as much groundwater as possible to keep it from entering the basements as it heads to the sea.
But Tepco estimates the wells can only pump up 100 of the 400 tons leaking into the buildings every day.
Tepco was going to release the well water into the sea because its radioactivity is much lower than the safety standards for drinking water set by the World Health Organization.
It suspended the plan on May 13 after the local fisheries association vetoed the idea, fearing any further discharge would only worsen the already marred image of local seafood.
