People living along the Pacific Coast, including in Sitka and Southeast Alaska, have been wondering about the impacts of radiation in the food supply ever since the March 2011 earthquake in Japan and Fukushima Dai-ichi nuclear power plant meltdown.
Dr. Lee Cooper of the University of Maryland, a Scientist in Residency Fellow at the Sitka Sound Science Center, will discuss the current state of the science on Fukushima radiation and its likely impact on the Gulf of Alaska during a brown-bag lunch presentation from 12:30-1:30 p.m. on Friday, March 14, at the Sitka Pioneer Home Chapel. Bring your lunch and questions to the presentation, which is sponsored by the Sitka Sound Science Center and the National Science Foundation.
According to the Sitka Sound Science Center:
It is projected that dissolved contaminants, particularly the radioactive isotopes of cesium, 137Cs and 134Cs from the Fukushima Dai-ichi Nuclear Power in Japan, will reach Southeast Alaska this year. Because the amount of radiation released is uncertain and the accident site is still leaking to some extent, it is difficult to know exactly what the peak concentrations of radioactive cesium will be in local waters, but it is not likely to exceed levels that were observed during the bomb fallout era 40 to 50 years ago. Cesium is chemically very similar to potassium, which is a common ionic salt in seawater, so fortunately the concentration of cesium into the foodweb and into seafood harvested for food is comparatively modest.
Nevertheless, it is important to put into perspective the potential risks involved and communicate this to the public. This talk will summarize the newest scientific information that is available on the impacts of the accident, based upon a special session held in late February at the Ocean Science Meeting in Honolulu and attended by scientists studying Fukushima impacts, ranging from Japan and East Asia to the Woods Hole Oceanographic Institution.
