"Radiant Seaweed" - US West Coast Seaweed Showing Radioactive Cesium From Fukushima.(Simply Info)
New testing done by Worcester Polytechnic Institute, Dept. of Civil and Environmental Engineering found Fukushima cesium in US Pacific sea weed. The samples were standardized against a known amount of cesium 137 and cobalt 60. The finding of cesium 134 would indicate this is at least partially from the Fukushima nuclear disaster.
“Washington State Pacific coast eel weed sample contained 0.22 pCi/g of Cs134 and 0.24 pCi/g of Cs137. It also contained 0.1 pCi/g of Co60”
These values converted to the more common bq/kg are:
Cesium 134: 8.14 Bq/Kg
Cesium 137: 8.88 Bq/Kg
Cobalt 60: 3.7 Bq/Kg
They also tested nori sheets from a market in Chiba prefecture Japan.
“One of two Japanese nori samples from a Chiba Prefecture market contained 1.1 pCi/g of Cs134 and 1.7 pCi/g of Cs137. (That’s 41 and 63 Bq/kg, respectively.) The other was nondetect for these isotopes.”
Cesium 134: 41 bq/kg
Cesium 137: 63 bq/kg
Cobalt 60: none detected
