LONG BEACH, Calif.—Scientists working together on Kelp Watch 2014 announced today that the West Coast shoreline shows no signs of ocean-borne radiation from Japan’s Fukushima nuclear power plant disaster, following their analysis of the first collection of kelp samples along the western U.S. coastline.

Kelp Watch 2014 is a project that uses coastal kelp beds as detectors of radioactive seawater arriving from Fukushima via the North Pacific Current. It is a collaborative effort led by Steven Manley, marine biology professor at California State University, Long Beach (CSULB), and Kai Vetter, head of applied nuclear physics at the Lawrence Berkeley National Laboratory (Berkeley Lab) and a nuclear engineering professor at the University of California, Berkeley.

Citizen science campaign aims to collect ocean samples and fund radiation analysis

Woods Hole Oceanographic Institution (WHOI) marine chemist Ken Buesseler began sampling and analyzing seawater surrounding the Fukushima Dai-ichi nuclear power plant three months after the 2011 disaster. Today, he launched a crowd sourcing campaign and citizen science website to collect and analyze seawater along the West Coast of North America as the radioactive plume travels 5,000 miles across the Pacific Ocean.

Japan fisheries data provides a look at how the ocean is faring 18 months after the worst accidental release of radiation to the ocean in history

Japan’s “triple disaster,” as it has become known, began on March 11, 2011, and remains unprecedented in its scope and complexity. To understand the lingering effects and potential public health implications of that chain of events, scientists are turning to a diverse and widespread sentinel in the world’s ocean: fish.

Events on March 11 began with a magnitude 9.0 earthquake, the fourth largest ever recorded. The earthquake in turn spawned a massive 40-foot tsunami that inundated the northeast Japanese coast and resulted in an estimated 20,000 missing or dead. Finally, the wave caused catastrophic damage to the Fukushima Dai-ichi nuclear power plant, resulting in the largest accidental release of radiation to the ocean in history, 80 percent of which ended up in the Northwest Pacific Ocean.

Cybersecurity expert Hathaway discusses risks of modern digital world

The near future of digital technology could allow citizens to turn on their toaster ovens via the Internet from just about anywhere, but these developments could pose serious threats to individuals’ safety, according to a cybersecurity expert.

Melissa Hathaway, a former senior director for cyberspace in the National Security Council, highlighted examples of the threats the Internet has created for both national and personal security during a University of Delaware Global Agenda speaker series presentation on Wednesday night, April 11, in Mitchell Hall.

An international research team is reporting the results of a research cruise they organized to study the amount, spread, and impacts of radiation released into the ocean from the tsunami-crippled reactors in Fukushima, Japan. The group of 17 researchers and technicians from eight institutions spent 15 days at sea in June 2011 studying ocean currents, and sampling water and marine organisms up to the edge of the exclusion zone around the reactors.

Led by Ken Buesseler, a senior scientist and marine chemist at the Woods Hole Oceanographic Institution (WHOI), the team found that the concentration of several key radioactive substances, or radionuclides, were elevated but varied widely across the study area, reflecting the complex nature of the marine environment. In addition, although levels of radioactivity in marine life sampled during the cruise were well below levels of concern for humans and the organisms themselves, the researchers leave open the question of whether radioactive materials are accumulating on the seafloor sediments and, if so, whether these might pose a long-term threat to the marine ecosystem. The results appear in the April 2 online edition of the journal Proceedings of the National Academy of Sciences (PNAS). (more…)

ANN ARBOR, Mich.— A year after the crisis at Japan’s Fukushima Daiichi nuclear power plant, scientists and engineers remain largely in the dark when it comes to fundamental knowledge about how nuclear fuels behave under extreme conditions, according to a University of Michigan nuclear waste expert and his colleagues.

In a review article in this week’s edition of the journal Science, U-M’s Rodney Ewing and two colleagues call for an ambitious, long-term national research program to study how nuclear fuels behave under the extreme conditions present during core-melt events like those that occurred at Fukushima following the March 11, 2011, magnitude 9.0 earthquake and tsunami.

*Berkeley Lab Researchers Developing Promising Treatment for Safely Decontaminating Humans Exposed to Radioactive Actinides*

The New York Times recently reported that in the darkest moments of the triple meltdown last year of the Fukushima Daiichi nuclear power plant, Japanese officials considered the evacuation of the nearly 36 million residents of the Tokyo metropolitan area. The consideration of so drastic an action reflects the harsh fact that in the aftermath of a major radiation exposure event, such as a nuclear reactor accident or a “dirty bomb” terrorist attack, treatments for mass contamination are antiquated and very limited. The only chemical agent now available for decontamination – a compound known as DTPA – is a Cold War relic that must be administered intravenously and only partially removes some of the deadly actinides – the radioactive chemical elements spanning from actinium to lawrencium on the periodic table – that pose the greatest health threats.
