Cesium-134, one of several radioactive isotopes released in the incident, is called the “fingerprint” of Fukushima because it does not occur naturally in the environment and has a relatively short half-life of only two years (the half-life of radioactive isotopes is the length of time it takes for half of the radioactivity to decay—therefore any cesium-134 detected would have had to come from a recent release). While C-134 was detected 100 miles due west of Eureka as recently as November 2014, confirming the arrival of Fukushima currents to our shores, the amount was well below the limit allowed by U.S. drinking water standards.
Cesium-137, which exists as residual background radiation leftover from nuclear testing in the mid-1900s (with a half-life of 30 years), is still being detected along the entire west coast at levels higher than would otherwise be present, though still well below government-established safety limits.
Much less radiation has swept into the seas off Fukushima than into the South Pacific where OVER 1000 nuclear bombs were exploded. Yet, conditions for sea life in the South Pacific seem to have recovered nicely:
The doomers that claim Fukushima radiation is destroying the Pacific should look at the test case of the Marshall Islands. The radiation there has been so bad people could not go back to their homes for over 50 years, YET, sea life is THRIVING:
‘Quite odd’: coral and fish thrive on Bikini Atoll 70 years after nuclear tests

Scientists say marine life has proved ‘remarkably resilient’ despite the Pacific island being declared a wasteland in the 1950s

The former island paradise of Bikini Atoll is slowing blooming back to life, 70 years after the United States dropped 23 nuclear bombs on it, including a device in 1954 that was 1,100-times larger than the Hiroshima atom bomb.
A team of scientists from Stanford University have been surprised to discover an abundance of marine life apparently thriving in the crater of Bikini Atoll, which was declared a nuclear wasteland after the bombings, with its 167 inhabitants relocated to other islands.
Steve Palumbi, a professor in marine sciences at the university, said the effects of radiation poisoning on ocean life have never been studied in-depth, and his team’s initial research suggests it is “remarkably resilient”.
Animals studied by scientists in and around the Chernobyl blast showed deformities and mutations, but the Stanford teams initial research suggest the marine life in Bikini may have fared significantly better.
Plutonium is very heavy, so it would have been confined to near the source. They only find it near to the reactors that exploded, not in the sea. Plutonium would not be transported in sea water because it would sink to the ocean floor.
