4170 Bq/Kg of Radioactive Cesium in Crickets in Iitate-mura, Fukushima

A researcher (vice president) at Tokyo University of Agriculture and Technology collected 500 crickets (1 kilogram) in Iitate-mura in Fukushima Prefecture, and found 4,000 becquerels/kg of radioactive cesium. He also tested locusts in different locations in Fukushima, and found radioactive cesium in them.

Bio-concentration at work. No information whether he tested other nuclides like radioactive silver (Ag-110m). Professor Bin Mori of Tokyo University found radioactive silver highly concentrated (1000 times the amount in the environment) in Nephila clavata he caught in Iitate-mura.

From Yomiuri Shinbun (1/12/2012):


A survey conducted by Hajime Fugo, vice president of Tokyo University of Agriculture and Technology (specialty: insect physiology) found over 4,000 becquerels/kg of radioactive cesium in crickets (500 of them that weigh about 1 kilogram) from within the planned evacuation zone 40 kilometers away from Fukushima I Nuclear Power Plant.


In another location, 200 becquerels/kg of radioactive cesium was found from locusts.


The survey was done in October last year. 500 crickets were collected in the northern part of Iitate-mura in Fukushima Prefecture, which is in the planned evacuation zone 40 kilometers from the plant. 2,000 locusts were collected in locations 60 to 80 kilometers from the plant, including Motomiya City (around City Hall), northern part of Sukagawa City, Koori-machi (near Town Hall) and near Inawashiro Lake in Inawashiro-machi.


Average 4,170 becquerels/kg of radioactive cesium was detected from crickets in Iitate-mura, 196 becquerels/kg from locusts in Sukagawa City, 82 becquerels/kg and 75 becquerels/kg from locusts in Koori-machi and Motomiya City respectively.

Umm, is the government and workers at all nuclear plants around the world going to admit, that nuclear power and the chemistry used are a danger now!? It is sad when you read about these situations and part of the end results that never change for the better.
