Government radiation monitoring in areas near Japan’s crippled Fukushima nuclear plant is unreliable, Greenpeace charged on Tuesday, with heavily populated areas exposed to 13 times the legal limit.
The environmental group said authorities were wasting time cleaning up evacuated areas and should prioritise decontamination efforts in places where people live, work and play.
Greenpeace found that in some parks and school facilities in Fukushima city, home to 285,000 people, radiation levels were above three microsieverts per hour. Japan’s recommended radiation limit is 0.23 microsieverts per hour. [...]
Fairewinds’ Chief Engineer Arnie Gundersen and Boston Chemical Data Corporation’s Founder Marco Kaltofen have an in-depth conversation regarding the challenges of measuring radiation exposures to people around the globe. Kaltofen explains the scientific methodology involved in accurately analyzing and measuring radioactive releases from Fukushima Daiichi, including the impact of hot particles on human physiology.
Arnie Gundersen: Hi, I am Arnie Gundersen from Fairewinds. This is the first video on the new Fairewinds site. We worked really hard to make it user friendly and searchable and we hope you like it. If you have any questions, please send us a comment.
You recall Marco Kaltofen. He presented at the American Public Health Association a couple of months ago and we heard his presentation. Today, I had a longer conversation with Mr. Kaltofen. Mr. Kaltofen runs the Boston Chemical Data Corporation and he is a professional engineer. He talks about radiation in the environment and especially radiation from the Fukushima accident. I hope you enjoy the conversation between Mr. Kaltofen and me. Continue reading »
The highest is Watari District in Fukushima City, close to 20,000 becquerels/kg of radioactive cesium. Kashiwa City in Chiba and Ichinoseki City in Iwate, about 200 kilometers south and north of Fukushima I Nuclear Power Plant respectively, also tested rather high, with close to 6,000 becquerels/kg of radioactive cesium.
