As concern about climate change has grown, nuclear energy — long a polarizing subject — has gained increasing favorability. Its low carbon footprint, reliable power supply and strong safety record convinced many critics that nuclear power should be a bigger part of our energy mix.
That newfound favorability suffered a setback on March 11, 2011, when an earthquake struck off the coast of Japan. The resulting tsunami damaged the backup systems essential to the safe shutdown of the Fukushima Dai-ichi nuclear power station. Over the next several weeks, as the Japanese people struggled to limit the extent of the damage, a slow-motion accident unfolded. While the world watched, radioactive cesium, iodine and other nuclides were released to the air and surrounding ocean.
Suddenly, the nuclear power renaissance seemed very much in doubt.
For more than 50 years, Oregon State’s Department of Nuclear Engineering and Radiation Health Physics (NERHP) has been engaged in nuclear power plant design and safety research. Lately, our department has been in the spotlight because of our focus on creating safer and simpler nuclear technology, such as the NuScale small modular reactor. But Fukushima brought attention to a lesser-known competence at OSU: radioecology.
Oregon State is one of the last U.S. academic institutions actively doing research in this unique, interdisciplinary field, which focuses on the movement of radioactive nuclides and their impact on humans and the environment. We travel to places like Johnston Atoll in the Pacific to evaluate radiological risk and find strategies to clean up Cold War-era contamination. We study radionuclide uptake by plants and animals — findings that have been incorporated into environmental protection standards for the U.S. Department of Energy, as well as guidance by the International Atomic Energy Agency and the International Commission on Radiological Protection.
After Fukushima, we answered hundreds of calls from the public and media. In June 2011, we participated in a Woods Hole Institution expedition to the Fukushima coast on the research vessel Ka’imikai-O-Kanaloa with funding from the Gordon and Betty Moore Foundation and the National Science Foundation. We designed and built a radiological sampling system for seawater and helped collect and analyze marine organisms for contamination. We studied mechanisms of radiological contamination of tea plants in Japan. With Corvallis-based Earthfort, we tested the company’s proprietary compound for reducing the movement of radiocesium in soils in hopes that it might be used in Japan. And we joined the OSU Marine Council Action Coordination Team dealing with marine debris arriving on our coastline.
Our research has helped put Fukushima in perspective. The tragic accident caused a slowdown in nuclear power development worldwide. But today, scientists are reasonably confident that the radiation will have no measurable public health effects. And the best reasons for pursuing this energy technology remain: reliable power with minimal carbon emissions.
We will remain on the frontlines of reactor safety, radioecology and environmental protection. We will continue to advocate for more research and public education in radiation sciences so that as a society we can make informed choices about our energy mix.
Editor’s note: Higley’s expertise has been highly sought by news media covering the consequences of the Fukushima disaster. See her comments on the burial of radioactive wastes in the Nov. 5, 2012 Christian Science Monitor.

There are hundreds of tonnes on MOX fuel sitting on the floor of the Pacific Ocean. A constant leak of highly radioactive water from the corium that melted though the containment in three reactors going straight into the Ocean. Not to mention the airborne pollution.
People do not realise that this IS A MASS EXTINCTION EVENT and the bioaccumulation of radioactive substances WILL end all life on this planet.
Wonder why we are having extreme weather? – Hot particles in the stratosphere from Fukushima constantly circling the northern hemisphere.
There has been a total media cover up to the true extent of this ongoing crisis that gets worse by the day and no fix and no plan on how to fix.
Quote “scientists are reasonably confident that the radiation will have no measurable public health effects” the uninformed may say this but they are very very wrong. There is no fixing any of this tragedy – please stop telling people otherwise.
Just take a look at the following – Health effects – thanks to these unstoppable death machines;
To start with the nuclear industry does not have a satisfactory answer on what to do with the waste it produces. There is no technology to remove or clean up and this alone should be reason enough to stop.
The accident at Fukushima is a runaway train “China syndrome” times 3 (three corium’s are still melting). We will never be able to stop them and clean up, as a result Fukushima will kill all life on earth by the bioaccumulation of radionuclides in all species that breathe, drink or eat.
To promote nuclear as an answer to energy shortages is simply suicide – it is just a matter of time… Do you have children?
So when a large solar CME hits earth and takes down the cooling systems of a “Safe, clean, low carbon nuclear powerstation” we’ll have Fuku all over again but not just one.
People need to know that facts before making informed decisions and telling them it is safe is a lie and a crime to humanity.
The author and moderators of this article have no soul and have been bought by an industry that was set up to make bombs – disgusting evil display of couldn’t care less and at the price of our children’s lives.
Very safe, let us build lots more.
Uranium is far from “low carbon” – http://news.bbc.co.uk/1/hi/sci/tech/7371645.stm
Anyway CO2 produced by man is a drop in the Ocean – it is due to the sun – be informed!
Reasoned, well researched and accessible literature we can all use.
