Our dear friend and colleague, Professor Joonhong Ahn, died in Japan on Sunday, June 19; private services were held on Tuesday, June 21. Since his diagnosis of advanced liver cancer in April, 2015, and throughout his treatment regimen, he maintained a relentless pace of work in service to the profession, the department and his students.
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.
Graduate student, Ryan Pavlovsky, and Professor Kai Vetter went out to Half Moon Bay recently to measure radiation levels following some recent widely publicized measurements indicating increased radiation levels on a beach north of the town of Half Moon Bay.
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.
