Harvard University research revives use of decades-old famous St. Louis Baby Tooth Survey via St. Louis Post-Dispatch

Michele Munz

Harvard University neuroscientist and epidemiologist Marc Weisskopf is interested in the idea that early childhood can determine one’s health trajectory for life.

As part of a multimillion-dollar federal grant to study exposure to metals, his team at Harvard will revive the Baby Tooth Survey in St. Louis, a famous study in the 1950s and ’60s that involved measuring radioactive fallout in about 320,000 donated teeth.

The study helped speed approval of the Limited Test Ban Treaty in 1963, which barred nuclear weapons tests in the atmosphere, outer space and under water, likely saving millions of lives.

[…]

The leftover baby teeth from the Washington University-led research were discovered in 2001 in an old ammunition bunker at the university’s Tyson Research Center.

The teeth were donated to a small nonprofit, the Radiation and Public Health Project, whose director and sole employee Joe Mangano lives near Ocean City, New Jersey. The teeth are in a storage locker near his home.

[…]

But Mangano has maintained his excitement about possible discoveries to be made studying the teeth. A mutual friend introduced Mangano to Weisskopf, director of the Harvard Chan-NIEHS Center for Environmental Health, correctly guessing he would share in Mangano’s excitement.

“Teeth give this opportunity to get a picture of what is going on in early life,” Weisskopf said, “and the idea that some 60,000 people whose baby teeth are sitting in a closet somewhere is very intriguing to me.”

[…]

Part of the research will involve finding 1,000 adults in their 60s and 70s who participated in the Baby Tooth Survey and looking for associations between metal concentrations in their baby teeth and current cognitive health.

Most of the tooth survey participants are from the St. Louis area, and Missouri is home to about 33 Superfund sites — toxic waste dumps requiring federal long-term cleanup. Harvard’s study will require sending new toenail and blood samples.

[…]

Nuclear fallout

The idea for collecting the baby teeth was hatched in the mid-1950s during the build-up of the Cold War between the U.S. and Soviet Union, which together tested hundreds of nuclear weapons.

About 100 took place at a Nevada testing site, where a few ended up dropping much of their fallout over the Midwest, including one of the largest — the Tumbler-Snapper George test on June 1, 1952, when a 2,700-pound nuclear bomb detonated atop a 300-foot tower.

High-altitude wind took the radioactive cloud in different directions across the country. Much of the radioactive material fell over Iowa, Missouri and Illinois in a rainstorm, author Richard Miller recounted for a Post-Dispatch story in 2002. Miller wrote “The U.S. Atlas of Nuclear Fallout, 1951-62.”

[…]

A group of prominent St. Louis scientists and physicians was concerned about the effects of radioactive fallout from the tests. They formed the Citizens Committee for Nuclear Information, and with help from Washington University, created the Baby Tooth Survey.

The survey was considered a great citizen-scientist collaboration, set out to determine whether children’s bodies were absorbing radioactive fallout from atmospheric nuclear weapons testing.

It entailed volunteers visiting schools, churches and PTA meetings, churches, libraries and dental clinics distributing registration forms. Between 1958 and 1970, parents sent in thousands of teeth along with their information cards.

The study found that children born at the height of the Cold War in 1963 had 50 times as much strontium 90, a radioactive isotope found in bomb fallout, in their teeth as children born in 1950 before most of the atomic bomb tests.

Strontium 90 had ended up in pastures, in grass consumed by goats and cows. It worked its way into children’s milk and showed up in children’s bones and teeth.

Dissecting payouts for decontamination work in Fukushima via Japan Times

By Philip Brasor

Many of the print and broadcast features related to the 10th anniversary of the 2011 earthquake and tsunami addressed the current circumstances of the people affected, with a recurring theme of how difficult it has been to move on, especially for those who lost loved ones. Amid these stories was one that stood out like a rusty nail, since it covered a less sympathetic response to the crisis: greed.

three-part series in the Asahi Shimbun focused on the city of Tamura in Fukushima Prefecture, in particular a highland district called Utsushi-chiku with about 1,850 residents, mainly farmers. Some fled after hydrogen explosions at the Fukushima No. 1 nuclear power plant on March 12, 2011, though they weren’t ordered to since Utsushi-chiku was outside the mandatory evacuation zone. However, the government subsequently restricted the distribution of crops grown in the area, so agriculture stopped.

When local authorities recruited people for work to remove contaminated topsoil and reduce radiation from the explosion, many residents signed up since no skills or experience were needed. About 450 formed a special project team, supervised by local construction companies, that started doing cleanup work in November 2012. Each worker received a daily wage of ¥9,500, which was considered good pay. One woman worked between two and five days a week, 7½ hours a day. There was no work quota and, she reports, everyone enjoyed the neighborly camaraderie of toiling together.

The job officially ended in September 2014. The woman said she had made ¥3 million altogether, but there was more. The cleanup funds had come from the central government, and there was still about ¥1.3 billion unspent, so all the workers received a kind of bonus. In the end, each made on average about ¥35,000 an hour for all the work they did. The woman got an extra ¥7 million, which allowed her to send her son to a private university and buy a new car. Many workers received more. As the deputy team leader put it, “It was like money falling from the sky.”

According to a special documentary that NHK aired on March 10, ¥5.6 trillion has so far been spent on cleaning up contaminated areas, but much of it has been for things not directly tied to the cleanup itself. The goal was to bring the affected area back to “normal” as soon as possible so that evacuees could return, but, 10 years later, that hasn’t happened, or, at least, not to the degree originally envisioned. After 90% of the work was finished, an estimated 60% of the radiation had been reduced. The cleanup had become a self-generating public works project with its own profit motives for contractors and subcontractors.

[…]

NHK mainly accuses organizing entities for this waste of funds, so the residents of Utsushi-chiku can’t really be blamed for the excess money they made, since they didn’t endeavor to get rich off the cleanup operation. But in the summer of 2019, at a meeting to dissolve the project team, the deputy team leader confessed he had received millions in yen in extra payments. As it turned out, a total of ¥26 million had been paid to the team’s officials, and, when other members found out, they were angry. Three officials have since been “expelled” from the team, and are now pariahs in the town. The Asahi Shimbum implies that even some ordinary members may have been parties to expense padding and other accounting abnormalities.

One farmer told the Asahi Shimbum that before the cleanup, some residents received large compensation payouts from the government because of their relative proximity to the accident while others received much less, even if they were neighbors, thus giving rise to resentments. Once the cleanup started, however, everybody had the same chance to make money and nobody complained. The work, in fact, made it possible for them to endure and eventually return to farming. But what does that mean when, as a result, their sense of community has been destroyed?

Bill Gates’ bad bet on plutonium-fueled reactors via Bulletin of Atomic Scientists

By Frank von Hippel

One of Bill Gates’ causes is to replace power plants fueled by coal and natural gas with climate-friendly alternatives. That has led the billionaire philanthropist and Microsoft co-founder to embrace nuclear power, and building nuclear power plants to combat climate change is a prospect worth discussing. But Gates has been persuaded to back a costly reactor design fueled by nuclear-weapon-usable plutonium and shown, through decades of experience, to be expensive, quick to break down, and difficult to repair.

In fact, Gates and his company, Terrapower, are promoting a reactor type that the US and most other countries abandoned four decades ago because of concerns about both nuclear weapons  proliferation and cost.

[…]

The consortium that is to build the Versatile Test Reactor, at an estimated cost of up to $5.6 billion, includes Bill Gates’ Terrapower.

Gates is obviously not in it for the money. But his reputation for seriousness may have helped recruit Democratic Senators Cory Booker, Dick Durbin, and Sheldon Whitehouse to join the two Republican senators from Idaho in a bipartisan coalition to co-sponsor the Nuclear Energy Innovations Capabilities Act of 2017, which called for the VTR.

I wonder if any of those five Senators knows that the VTR is to be fueled annually by enough plutonium for more than 50 Nagasaki bombs. Or that it is a failed technology. Or that the Idaho National Laboratory is collaborating on plutonium separation technology with the Korea Atomic Energy Research Institute at a time when about half of South Korea’s population wants nuclear weapons to deter North Korea.

Small Modular and Advanced Nuclear Reactors: A Reality Check via IEEE

By M.V. Ramana

Abstract:Nuclear power has been declining in importance over the last quarter century, with its share of global electrical energy generation decreasing from 17.5 percent in 1996 to around 10 percent in 2019. Small modular and advanced nuclear reactors have been proposed as potential ways of dealing with the problems—specifically economic competitiveness, risk of accidents, link to proliferation and production of waste—confronting nuclear power technology. This perspective article examines whether these new designs can indeed solve these problems, with a particular focus on the economic challenges. It briefly discusses the technical challenges confronting advanced reactor designs and the many decades it might take for these to be commercialized, if ever. The article explains why the higher construction and operational costs per unit of electricity generation capacity will make electricity from small modular reactors more expensive than electricity from large nuclear power plants, which are themselves not competitive in today’s electricity markets. Next, it examines the potential savings from learning and modular construction, and explains why the historical record suggests that these savings will be inadequate to compensate for the economic challenges resulting from the lower generation capacity. It then critically examines arguments offered by advocates of these technologies about job creation and other potential uses of energy generated from these plants to justify subsidizing and constructing these kinds of nuclear plants. It concludes with an assessment of the markets for these technologies, suggesting that these are inadequate to justify constructing the necessary manufacturing facilities.

Advanced nuclear reactors no safer than conventional nuclear plants, says science group via Reuters

By Timothy Gardner

WASHINGTON (Reuters) – A new generation of so-called “advanced” nuclear power reactors that Washington believes could help fight climate change often present greater proliferation risks than conventional nuclear power, a science advocacy group said on Thursday.

President Joe Biden, a Democrat, has made curbing climate change a priority and has supported research and development for advanced nuclear technologies.

The reactors are also popular with many Republicans. Last October, the month before Biden was elected, the U.S. Department of Energy, awarded $80 million each to TerraPower LLC and X-energy to build reactors it said would be operational in seven years.

Advanced reactors are generally far smaller than conventional reactors and are cooled with materials such as molten salt instead of with water. Backers say they are safer and some can use nuclear waste as fuel.

“The technologies are certainly different from current reactors, but it is not at all clear they are better,” said Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists.

“In many cases, they are worse with regard to … safety, and the potential for severe accidents and potential nuclear proliferation,” said Lyman, author of the report UCS released Thursday called “‘Advanced’ Isn’t Always Better”.

[…]

But fuel for many of those reactors would have to be enriched at a much higher rate than conventional fuel, meaning the fuel supply chain could be an attractive target for militants looking to create a crude nuclear weapon, the report here said.

Also, nuclear waste from today’s reactors would have to be reprocessed to make fuel. That technique has not been practiced in the United States for decades because of proliferation and cost concerns. Other advanced reactors emit large amounts of radioactive gases, a potentially problematic waste stream.

Lyman said advanced nuclear development funds would be better spent on bolstering conventional nuclear plants from the risks of earthquakes and climate change, such as flooding. The report recommended that the Department of Energy suspend its advanced reactor demonstration program until the Nuclear Regulatory Commission (NRC) requires prototype testing before reactors can be licensed for commercial use.

Toxique: The Aftermath of French Nuclear Testing in the South Pacific via Princeton School of Public and International Affairs

By B. Rose Huber

Between 1966 and 1996, the French government conducted 193 nuclear weapon tests in the islands of the South Pacific. These explosions profoundly altered the health, wellbeing, and environment of the people living in this region, who spent decades amid radioactive polluted air, water, and soil.

Using hundreds of declassified French government documents, on-the-ground interviews in France and in Polynesia, and countless hours of advanced computer simulations, a new book co-authored by a researcher at Princeton’s Program on Science and Global Security (SGS) challenges the official public story of the human and environmental aftermath of French nuclear weapon testing in the South Pacific. Many of the documents, interviews, and simulations are on a dedicated new website in French and English that is being released with the book.

“Toxique,” released in French on March 10, was co-authored by Sebastien Philippe, associate research scholar with SGS, which is based at the Princeton School of Public and International Affairs; and Tomas Statius, a journalist from the award-wining French investigative media Disclose. Also involved in the project is Interprt, a collective of spatial designers focusing on environmental justice issues who designed the associated online platform.

The book is the result of a two-year exploration of the consequences of this nuclear testing and the continued struggle of local communities and veterans to seek justice and compensation. It finds that the total population exposed above the threshold necessary for compensation could be 10 times more than is currently believed based on existing government studies. It also shows how French veterans were exposed to radiation during the tests, from the maintenance of contaminated equipment, and during the attempted clean-up of the atolls.

In this episode of Endnotes, Philippe describes what motivated him to pursue this investigative project, and how he hopes the results will help the people of the South Pacific.

仲間の自死、見せかけの復興「このまま戻れない」…原発事故「自主」避難者たちの不条理な現在地 via 東京新聞

東京電力福島第一原発事故の後、福島県内の旧避難指示区域外から逃れた人たちは「自主避難者」と呼ばれ、さまざまな支援の外に置かれた。同県郡山市から川崎市に母子避難した松本徳子さん(59)もその1人だ。自主避難者への住宅無償提供が打ち切られた後、自死を選んだ同郷の母親もいた。

「避難をした人、しない人。それぞれの選択が尊重される社会を願ってきたが、かなわなかった。不条理です」と自主避難者の現状を見つめる。(安藤恭子)

◆いないことにされる私たち

 「五輪に向け、福島は今『復興』の一色。その一方、私たち区域外避難者はいないことにされ、この国は原発をやめようとしない」。3月10日夕、横浜・象の鼻パークで開かれた東日本大震災の追悼イベント。松本さんが聴衆に語りかけた。「この10年で何かが変わった、とされることには憤慨しています」 

松本さんが生まれ育った郡山は、福島第一原発から約60キロ離れている。当初は避難するつもりはなかったが、震災の3カ月後、当時12歳の次女が大量の鼻血を出し、吐き気や下痢をもよおすようになった。「少しでも被ばくしない所へ」。自営の夫を残し、2011年秋に川崎市に移転した。 

17年3月、自主避難者への住宅の無償提供政策が打ち切られたが、郡山には帰れなかった。「自宅の庭にはまだ汚染物が残っていたから。娘も体調を崩した怖さを覚えている」と松本さん。除染は進んでも、放射線量が高い場所や食べ物は存在する。次女は川崎で高校を卒業し、就職した。

(略)

◆声を上げられなかった人たちの分まで

 16年にできた「避難の協同センター」(東京)の代表世話人に就き、自主避難者らの相談に応じてきた。17年5月、相談者の1人で郡山から母子避難していた女性が自死をした。「睡眠剤をのんだから、またね」。電話で話したのが最後だった。 

女性は仕事を掛け持ちし、自分の物を切り詰めて子どもたちの学費を貯金していた。家族に母子避難を反対され、自分を責めてもいた。「頑張っていた彼女を、貧困が追い詰めた。住宅無償提供の打ち切りを決めた国や行政の選択は間違いだ」。五輪を前に自主避難者をなかったことにする「見せ掛けの復興」がうたわれている。松本さんの目には「棄民政策」と映る。

(略)

2月の地震でも原発事故の恐怖はよみがえり「このままでは帰れない」と心に決めている。戻れば、福島が大丈夫と認めることになるからだ。「子どもたちに、原発が安全なエネルギーと思ってほしくない。同じ過ちを繰り返さないため、声を上げられなかった人たちの分まで、おかしいと言い続けなければと思っているんです」

「人生を懸けてビキニ事件語った」 元乗組員、大石又七さん死去 via 毎日新聞 (goo ニュース)

[…]

第五福竜丸展示館の学芸員、市田真理さん(53)は「人生を懸けてビキニ事件を語っていた」と振り返る。最後に会ったのは2019年12月。学生を連れて行くと、「話したいことがたくさんある」と言ったという。その後は新型コロナウイルスの感染拡大で面会がかなわず、「もう一度、一緒に講演する約束だったので、信じられない。命懸けで伝えようとしたことを受け継いでいかなければ」と声を詰まらせた。

 平和研究が専門の竹峰誠一郎・明星大教授(44)は「(差別や偏見から)第五福竜丸の船員の多くが沈黙せざるを得ないなか、大石さんは証言した先駆者。大石さんの存在なくしてビキニ事件の深さや背景は語れない」と功績を語った。大石さんと一緒にマーシャル諸島を訪ねており、「マグロやカツオの知識が豊富で、船に乗った時は輝いていた。被害を受けなければ太平洋の海と生きた人なのだろう。優しい人だったが、証言には悔しさや怒りがあった」と思いをはせた。

 高知県でビキニ事件の被災者支援を続ける市民団体「太平洋核被災支援センター」事務局長の山下正寿さん(76)=高知県宿毛市=は「自らの体験を積極的に発信し、強い信念で活動していた」と話す。山下さんは高校教諭だった1988年、高校生と被災調査を進めるなかで大石さんと知り合った。大石さんが生徒らを見つめ、「事件は隠してはいけない。事実を素直に受け止め、調査を頑張ってほしい」と強く訴える姿を今も覚えている。ビキニ事件をテーマにした講演会でも何度か顔を合わせたといい、「核被害の問題に広く関心を持ち、廃絶を訴えた人を失ってしまった」と惜しんだ。【椋田佳代、松原由佳】
