#Radiation in Japan: Spiders in Iitate-mura Concentrating Radioactive Silver 1,000 Times, EX-SKF, November 8, 2011:
Dr. Bin Mori is a professor emeritus at University of Tokyo, Faculty of Agriculture.
In his post on October 30, Professor Mori wrote about his discovery, probably the world first, he made in spiders (Nephila clavata) he caught in Iitate-mura, Fukushima Prefecture
The following is my translation of Dr. Mori’s October 30 blog post, with his express permission:
- Cs-134 ＋Cs-137 = 3,656 Bq/kg
- Ag-110m ＝1,397 Bq/kg
In the forest where the spiders were caught, the ratio of radioactive cesium (134+137) to Ag-110m was about 2,500 to 1. Using the above numbers, I calculated that nephila clavatas bio-concentrated the radioactive silver in the soil to about 1,000 times.
