Regarding the Sept. 15 Kyodo article “Cesium in sea may return in 20 to 30 years“: I was wondering how cesium could affect sea life and the repercussions it could have on those who eat seafood.

The possible return of cesium-137 to Japan’s coast (after circulating in the Pacific Ocean in a clockwise pattern) and its nearly 30-year half-life suggests that the quantity released into the ocean from the Fukushima No. 1 nuclear plant won’t disperse much and that edible fish will be exposed to radiation.

In that case, should we not follow the progress of the cesium flow in the ocean and conduct tests to guarantee that fish are safe to eat? Or will the cesium be sufficiently dispersed so that it won’t be harmful to humans? Anyway, thanks for your hard work.
