The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Remembering the victims of the atomic bombings 75 years ago — IPPNW peace and health blog

As we recall the unprecedented horrors that the citizens of Hiroshima and Nagasaki experienced on August 6 and 9, 1945, we reaffirm the determination of our organizations to ensure that nuclear weapons are never used again. There is no vaccine against the deadly threat of nuclear war, which could prove to be humanity’s “final epidemic.” We therefore call on all nations to join the 2017 Treaty on the Prohibition of Nuclear Weapons.

The complexities and pitfalls of citizen science

One such tactic, which was witnessed after Fukushima, occurred through the reframing of radiation risks as simplistic and natural, unrelated to the specific risks associated with Fukushima. For instance, the government distributed pamphlets that explained that radiation naturally exists in our food, ch as the potassium levels present in bananas.

Yet such information is irrelevant to the hazards of internalizing fission products from a nuclear power plant. While bananas have naturally occurring potassium, it would require eating around 20 million bananas to get radiation poisoning.  On the other hand, each radionuclide released during nuclear meltdown events like Fukushima possesses specific biological signatures and presents particular risks when inhaled or ingested.

“……..there are inherent political complexities involved when citizens or nongovernmental organizations step in and claim expertise in areas typically reserved for state agencies and experts. Like those entities, citizen science has its own potential pitfalls.

For one, corporate polluters or state agencies can potentially exploit citizen science, delegating the monitoring of contamination to the victims of a disaster. For instance, by the end of this year, Japan’s Nuclear Regulation Agency plans to remove 80 percent of radiation monitoring posts in Fukushima, arguing that the radiation levels in many areas have stabilized themselves—owing also in part to the presence and efficiency of monitoring networks provided by citizens. This decision has been controversial, since problems of radioactive contamination persist in Fukushima. For instance, one of the main radioactive pollutants, Cesium-137, has a long lifespan and can emit radiation for nearly 300 years.

Retiring these posts will force citizen scientists to take on the burden of monitoring, shifting liability for ensuring safe living conditions onto the shoulders of the nuclear victims. In addition, the growing impact of citizen science can lead to reduced public expenditure, minimal government intervention, and risk privatization, meaning that risk becomes individual and private. Too much delegation to citizens runs the risk of creating societies where individuals have to take care of themselves in increasingly polluted environments, while interpreting complex data about controversial environmental dangers. And not every community can afford to purchase expensive monitoring devices or test food in a consistent manner.

Citizen scientists also risk reproducing forms of ignorance around certain hazards.   n post-Fukushima Japan, what is meant by the “science” of citizen science is often synonymous with a tracking and monitoring agenda, where individuals resort to the very same technologies and knowledge forms used by states, nuclear lobbies, or radiological protection agencies.

Yet many anthropologists and historians have argued that what we know (and don’t know) about the extent of radiation hazards and dangers was embedded in a culture of secrecy, denial, and propaganda that was shaped by the nuclear arms race of the Cold War. Considerations over international security and political stability were often prioritized over the safety of workers or citizens who had been exposed to radiation. As a result, some of the negative effects of radiation were downplayed through different tactics.

One such tactic, which was witnessed after Fukushima, occurred through the reframing of radiation risks as simplistic and natural, unrelated to the specific risks associated with Fukushima. For instance, the government distributed pamphlets that explained that radiation naturally exists in our food, ch as the potassium levels present in bananas.

Yet such information is irrelevant to the hazards of internalizing fission products from a nuclear power plant. While bananas have naturally occurring potassium, it would require eating around 20 million bananas to get radiation poisoning.  On the other hand, each radionuclide released during nuclear meltdown events like Fukushima possesses specific biological signatures and presents particular risks when inhaled or ingested. During my fieldwork in Fukushima, I witnessed that this legacy of misinformation was carried on by some citizens who unwittingly replicated these propagandist forms of knowledge by making similar naturalistic or overly simplistic comparisons.

As citizen science efforts grow, it is also critical to consider to what extent citizen involvement might put individuals at risk of adverse health effects. This is a tricky question when one considers that certain members of the population, like children, are more sensitive to radiation than others. In Fukushima, some Japanese parents have understandably opted to evacuate rather than rely on citizen science, arguing that doing so would expose their children to unacceptable levels of radiation and that forcing children to be responsible for their own safety is unethical.

Citizen scientists are hardly homogeneous groups, as mothers, farmers, and urban citizens do not experience hazards and recovery in the same way. In that regard, factors such as gender, employment, and social class strongly influence why people enter citizen science, how science is mobilized, and how data about a controversial hazard ends up being interpreted. For instance, people like Natsuo have used the results gathered by citizen science to highlight the dangers of living in Fukushima, while other citizen science organizations help bring people back to their beloved region. These conflicts can result in even more fragmented communities and conflicts within and around citizen science. ……

In Japanese, two words—shiru and wakaru—can be used for the verb “knowing.” Shiru means “to find out” or “to learn.” It implies a process of acquisition of knowledge and information. Wakaru, on the other hand, is closer to “understanding this knowledge.” Shiru comes before wakaru, and in a way, one can know but not necessarily understand. Wakaru consequently shows a greater and more personal level of comprehension often based on a given context.

For Masayuki, state institutional experts possessed shiru, but not wakaru. Having been directly affected by radioactive contamination, Masayuki strongly believed that the inhabitants of a place, the jūmin (literally, the people who resided) were best suited to manage their life in a post-Fukushima Japan.  https://www.sapiens.org/culture/fukushima-citizen-science/

New fast test to detect ionising radiation

Scientists create a speedy finger-prick test to scan for radiation exposure in mice, Stat, By JULIET ISSELBACHERJULY 15, 2020  
Researchers have developed a simple finger-prick test that scans a single drop of blood to rapidly determine whether the body has been exposed to toxic levels of radiation.

Catastrophic radiological events — like nuclear detonations — can threaten massive populations with acute radiation syndrome, which wreaks havoc on the gastrointestinal system and destroys bone marrow, leading to infections and internal bleeding. In preparation for the possibility of such a public health disaster, scientists at Ohio State have devised a speedy and scalable method for estimating radiation exposure. They published their proof-of-concept research, conducted in mice, Wednesday in Science Translational Medicine.

Timing is key when it comes to assessing radiation dosage in members of an exposed population. Victims above a certain dose threshold require immediate and aggressive treatment, such as a blood transfusion or cytokine therapy.

“Early detection will save lives,” said Naduparambil Jacob, senior author of the study and a molecular biologist at Ohio State University Comprehensive Cancer Center.
The current “gold standard” test for radiation exposure is a dicentric chromosome assay, which looks for hallmarks of radiation-induced DNA damage. The problem is that this test takes around three or four days to yield results — a waiting period that can make it harder for clinicians to know how to proceed and can potentially jeopardize patient outcomes.
“If it takes you four days to get the result, then it’s not helpful in immediate management,” said C. Norman Coleman, a researcher at the National Cancer Institute who was not involved with the study. “The idea of getting some kind of number pretty quickly that tells you what you need to do is useful for the medical system and also for the patient.”

The test Jacob’s team developed has the capability to turn out a number within hours……….   https://www.statnews.com/2020/07/15/radiation-syndrome-exposure-test/

Citizen science and Fukushima radiation

Being Clear-Eyed About Citizen Science in the Age of COVID-19

An anthropologist explores the network of citizen monitoring capabilities that developed after the Fukushima nuclear disaster in Japan in 2011 for what they might teach all of us about such strategies for the covonavirus pandemic. Sapiens MAXIME POLLERI / 15 JUL 2020 “……………  The earthquake and subsequent tsunami led to core meltdowns within some of the Fukushima power plant’s nuclear reactors. This malfunction, along with other technical incidents, resulted in the atmospheric release of radioactive pollutants, which spread predominantly over the northeastern part of Japan, forcing a widespread evacuation of Fukushima residents. By March 12, the area around the power plant had been evacuated; those living and working within 20 kilometers of the radius of the plant were forced to relocate. In the days, weeks, and months following this disaster, uncertainty around the scale and extent of contamination grew swiftly—much like what we see occurring throughout the world during the COVID-19 pandemic.

Most notably, the public grew increasingly concerned about the legitimacy of institutional experts’ ability to control and explain the risks of residual radioactivity, while citizens like Natsuo were unable to get adequate information through traditional media venues. Initially, data about radioactive contamination came sporadically and was often explained in hard-to-understand metrics by scientists who were cherry-picked by the state to send reassuring messages to citizens.

Moreover, radioactive contamination was later found to be present in some food products and in school yards where children had been playing that lay beyond the official zone of evacuation. Over the ensuing months and years, the public lost confidence in the state’s response and began to take matters into their own hands, mobilizing expert practices of their own. Widespread grassroot actions led to citizen science networks in which people tracked radiation in their environment, organized learning workshops on radiation dangers, and tested food for contamination, often through local organizations or individual households.

As an anthropologist who conducted fieldwork on the Fukushima nuclear disaster between 2015 and 2017, I came to realize that citizen science can rise up to fill in the gaps of state responses toward crises, for better or for worse. As we’ve seen play out throughout the COVID-19 pandemic in various parts of the world, governance and leadership have often been confusing, mismatched, and at times utterly misleading. The case of Fukushima offers lessons about both the promises and pitfalls of citizen science and how civil society is playing an increasingly important role in managing various disasters, catastrophes, and crises.

The Geiger counter of Masayuki was not silent for long before it began to emit the distinctive “clicking” sound associated with radiation monitoring devices. The “click” grew louder in intensity as we located a hot spot, an area where the level of radiation is significantly higher than elsewhere. Masayuki dutifully noted the number provided by the device before leaving to search for another hot spot. We were standing in the Japanese village of Iitate, situated in the prefecture of Fukushima. It was common at this time for citizens to own their own Geiger counters—often purchased off the internet using international donations or made at home as DIY devices—to measure the level of radiation around them.

When I first came to this rural village in the spring of 2016, more than five years had passed since the nuclear disaster. The forced evacuation of citizens from Fukushima and the surrounding areas had proved short-lived; by 2012, the Japanese state had already embraced a policy of repatriation to irradiated areas like Iitate village, which is where I met Masayuki and citizens like him in 2016. ……….

While happy to be back in their beloved region, many residents were critical of the state radiation-monitoring networks that were supposed to provide them with adequate information to allow them to live safely in the village. Indeed, state data on radiation was often provided through fixed monitoring in precise locations or through an average radiation level taken in the village. This kind of information was not practical enough for residents, who wanted to know the specific radiation levels behind their houses or in their rice paddy fields.

Likewise, official depictions of radiation levels through clear-cut chromatic zones did little to offer the citizens reassurance. As a result of the perceived limitation of state measures, residents quickly decided to track radiation themselves as a means to keep the map of their village relevant—often finding contamination that was not evident from state mapping. In the house of one farmer, I witnessed homemade models that exhibited a 3D topography of Iitate’s geographical landscape. These models had been made using 3D printers, and the level of radiation had been monitored by the citizens themselves.

In particular, the local knowledge of the geography of Iitate helped citizens to attain a level of precision that far exceeded that of the government map. Citizens soon learned that radiation doses could be higher at the bottom of a hill than farther upslope or that the woods behind one’s home, having trapped radiation, might impact the radiation level inside houses. These practices helped strengthen a community that had previously felt helpless in the face of an imperceptible radiation threat. Geiger counters became the ears and eyes of citizens like Masayuki, enabling them to make sense of and gain some semblance of control over a hazard that cannot be registered by the senses.

After the Chernobyl nuclear disaster in 1986, one of the main sources of radiation exposure stemmed from consumption of food products such as milk or wild mushrooms that had been contaminated by radioactive fallout. In an effort to make sure that this did not happen in Japan, the government took on the task of testing the food produced in Fukushima, implementing a limit to the allowable amount of radioactivity in food products.

Within months after the meltdowns, the government assured the public of the safety of its food products, encouraging citizens to consume foods sold at public fairs and other public events. However, citizens of Fukushima also consume food harvested from streams, forests, home gardens, and mountain areas—where state monitoring was largely absent or insufficient.

Again, citizens mobilized to fill in the gaps in food testing: With the help of public donations, citizen scientists were able to purchase scintillation detectors, which are used to measure radioactive contaminants in foodstuff. Such testing enabled citizens to gain an understanding of the types of foods most prone to radioactive contamination, such as mushrooms, green leafy vegetables, citrus, sea cucumber, and seaweeds. This in turn helped people avoid eating the most risky foods. Together with state monitoring, such citizen science practices resulted in lower consumption of contaminated foods.

While such examples demonstrate the power and potential of citizen science, there are inherent political complexities involved when citizens or nongovernmental organizations step in and claim expertise in areas typically reserved for state agencies and experts. Like those entities, citizen science has its own potential pitfalls……..  https://www.sapiens.org/culture/fukushima-citizen-science/
