New Berkeley Airborne Radioactivity Monitor System is Online!
The Berkeley Radwatch team has installed a new system that allows us to see natural airborne radioactivity, in (almost) real time. This system is unique world-wide as it is not only based on a high-resolution and highly sensitive gamma-ray detector which collects data continuously but makes the data available to the public on an hourly basis. The detection system allows us to measure and identify very small amounts of specific radio-isotopes we can find in our environment. 

This project represents an interesting intersection between research and public education to better understand some of the radiation that is part of the world we are living in. We encourage everyone to check it out and observe the changes over time. We will continue to upgrade the site by providing more information and detailed data from the nuclear radiation detector and the weather station. We will offer ideas for research projects to analyze and study the changes of radio-isotopic concentrations over time and correlations with the meteorological data we are providing.

Reflecting our expanded activities in monitoring radiation we have established a new initiative called Berkeley Rad Watch. The former Berkeley Air and Water Monitoring activity will be part of it. We will continue to perform a wide range of air and sample measurements and will continue to release the data and results as unfiltered and unrestricted as before. In addition to facilities on UC Berkeley campus, we are now using measurement facilities at Berkeley Lab, such as the Low-Background Counting Facility. With the new website, we updated the Frequently Asked Question section addressing some more recent concerns about the expected arrival of small amounts of radioactive cesium on the North American West Coast over the next years.

NE graduate student Ryan Pavlovsky measures and analyzes radiation on beaches in Half Moon Bay – Variations in radiation levels can be explained by variations of naturally occurring thorium and uranium

Ryan Pavlovsky, one of our graduate students, and NE professor Vetter went out to Half Moon Bay recently to check out radiation levels following some recent widely publicized measurements indicating increased radiation levels on a beach north of the town of Half Moon Bay. In addition to a simple Geiger counter they took a state-of-the art, high-resolution gamma-ray spectrometer to find out what is causing the variations of the radiation levels. Ryan's report can be read here. As the main outcome, he can explain the increased radiation levels by the increased concentration of naturally occurring thorium and uranium in the sand. No radiation that can be attributed to the releases from Fukushima is observed. Detailed sand measurements are still ongoing. Stay tuned.

NE Professor Vetter and Keenan Thomas are part of new Kelp Watch 2014 Initiative

NE Professor and Head of Applied Nuclear Physics at Berkeley Lab Kai Vetter and Keenan Thomas have joined forces with Professor Steven Manley from California State University, Long Beach (CSULB) to launch “Kelp Watch 2014,” a scientific campaign designed to determine the extent of radioactive contamination of the state’s kelp forest from Japan’s damaged Fukushima nuclear power plant following the March 11, 2011, earthquake and tsunami.

The project will rely on samples of Giant Kelp and Bull Kelp from along the west coast from Alaska to Baja California as well as from Chile.

“The California kelp forest is a highly productive and complex ecosystem and a valuable state resource. It is imperative that we monitor this coastal forest for any radioactive contaminants that will be arriving this year in the ocean currents from Fukushima disaster,” said Manley, an expert in marine algae and kelp. “I receive calls and emails weekly from concerned visitors and Californians about the effect of the Fukushima disaster on our California marine life,” he continued. “I tell them that the anticipated concentrations that will arrive are most likely very low but we have no data regarding its impact on our coastal ecosystem. Kelp Watch 2014 will provide an initial monitoring system at least in the short-term.”

The project includes the participation of 19 academic and government institutions and three other organizations/businesses. These participants will sample kelp from the entire California coastline as far north as Del Norte County and as far south as Baja California. The sampling will begin in mid-February and will end in late winter. “What I have attempted to do is to organize marine scientists and educators from up and down the coastline to collect a large amount of kelp several times a year so that we can ascertain the amount of radioactive material entering our kelp forests,” Manley explained. “The response has been overwhelming. Recently I was contacted by a scientist in Washington State, who wants to send samples. I said ‘Sure.’”

Sampling will take place several times in 2014, and processed kelp samples will be sent to the Lawrence Berkeley National Lab’s Low Background Facility for detailed radionuclide analysis. As data becomes available it will be posted for public access. “Working with Dr. Vetter and his group is a perfect collaboration because of their vast experience in measuring radioactivity in a variety of biological samples, including seaweeds,” Manley noted. “His enthusiasm and support of Kelp Watch 2014 has been most gratifying. If the kelp takes up the radioactive material, we should detect it.”

Vetter pointed out that “UC Berkeley and Berkeley Lab’s analysis within the new Kelp Watch initiative is part of a larger, ongoing, effort to measure Fukushima related radionuclides in a large variety of objects. We have two main objectives—to learn more about the distribution and transport of these materials in our world, and to make the results and explanations available to the public.

“Making our results available is a critical aspect of our work as it allows us to address concerns about Fukushima radiation levels and to explain the meaning and potential impact of these levels,” he added, “particularly in the context of the natural radiation background we are exposed to in our daily lives.”

Several institutions—Moss Landing Marine Laboratory (California State University), Marine Science Institute (UC Santa Barbara), Coastal and Marine Institute (San Diego State University) and CSULB—have volunteered to serve as regional processing centers where needed. Also participating are marine scientists from the Universidad Autónoma de Baja California in Baja Norte Mexico.

“At the present time this entire initiative is unfunded by any state or federal agency, with time and costs being ‘donated’ by the participants,” Manley said. “I hope that this changes. USC Sea Grant funded an earlier related study of mine and I hope it or some other funding agency will help fund this more extensive project. “Still, more participants are signing up weekly,” he concluded. “We encourage scientists, educational institutions and other interested organizations to participate in the collecting and/or processing.”

NE Grad wins Big Ideas@Berkeley: Contest Results

Congratulations to NE Grad Tuan Hoang and his collaborators Hanh-Phuc Le (EECS) and Long Tran (CEE, Transportation) who were awarded 1st place ($5000) in the Clean & Sustainable Energy Alternatives category of the Big Ideas@Berkeley contest for their entry PT-EGen: Harnessing the Energy of Moving Cars.  Their project was among 37 chosen from over 160 submissions received from several UC campuses.

They propose to build a device that can be installed on streets, favorably downhill sections of steep hills like those in SF or Berkeley hills, or on highway exits, to slow down cars leaving the highways. These devices can also replace current speed bumps at areas needing traffic calming devices such as schools, hospitals, etc. and many other scenarios. These devices would be installed in modules and not cause drastic changes to current roads. When vehicles run over the devices, they will be pressed down and the energy collected will be stored in the type of elastic energy of the coils and  converted to electricity stored in batteries for later use. This device is not a "clean" device since energy is harnessed from vehicles moving on the roads, however, there are situations where these devices can bring favorable consequences. Highways are the best places to implement this idea since drivers may complain about the energy they are giving up, although extremely small. Policy and licensing are the biggest hurdle.

Announcing the Death of Professor Paul Chambré

(Photo Credit: Archives of the Mathematisches Forschungsinstitut Oberwolfach)

It is with sadness that I announce the passing of an esteemed and distinguished faculty member of the Department of Nuclear Engineering, Emeritus Professor Paul L. Chambré on April 13, 2013. He was 94 years old.

Paul joined the faculty of Mathematics Department, University of California, Berkeley as an Assistant Professor in 1951, after he received his PhD degree in Mechanical Engineering of UC Berkeley. In July 1960 he was jointly appointed as an Associate Professor by Mathematics Department and Nuclear Engineering Department, and then promoted to Professor in 1962. He led the research and education in the fields of applied mathematics, neutron transport, mathematical modeling for reactor safety, such as LOCA, optimal feedback control of a nuclear reactor, heat transfer in two-phase flow, and later radionuclide transport in geological media for nuclear waste management. He retired from the University of California in 1989, but continued his affiliation as Professor of the Graduate School.  Paul played a major role in launching the careers of his students and in mentoring of junior colleagues.  He will be missed.
