[...] Cesium-137 has a radioactive half-life of 30 years, while cesium-134 loses half its radioactivity after two. Fisher said concentrations of the isotope might undergo a “moderate buildup” in marine life higher up the food chain, but it’s not likely to concentrate as much as some dangerous industrial toxins like mercury. [...] 

Japan’s agriculture and fisheries ministry reports 13 types of fish have been caught off their shores with cesium levels above regulatory limits in recent weeks, and those limits are scheduled to go down. [...]
