US institution “Very low level of contaminant from Fukushima detected in West coast”/ Large areas left untested
On 11/10/2014, Woods Hole Oceanographic Institution announced they detected Cesium-134 from seawater of west coast of US.
Half-life of Cs-134 is only 2 years, therefore the detected Cs-134 originated in Fukushima for sure. They didn’t comment the specific reading of the contamination, but stated it was lower than 2Bq/m3 (> 0.2 Bq/m3), which is largely lower than the “harmful level”.
The sample was collected off the northern California coast this August.
The map below shows the sampling point and the rough readings of Cs-134, which was released by the institution.
Fukushima Diary found that they didn’t collect samples in the large area of the coast (red circled) though they took samples relatively throughout offshore.
Cs-134 was detected at 10 sampling locations but seawater is not tested at the nearest coastal area for some reason.
At this moment, Fukushima Diary hasn’t found the reason why they didn’t test the samples, where can be the most crucial for public health.
