For anyone interested, updated in April, on tuna, Cesium 137 mentioned...
It’s much worse than that. For the record:
The government ceased monitoring [at least publicly] radioactive isotopes from Fukushima well over a decade ago and the site has been leaking/dumping radioactive water continuously ever since due to natural springs flooding the corium (the melted cores).
I’ve not consumed Pacific seafood since that time, knowledgeable of the effects of Cesium 137, which mimics calcium (goes to the bones), has a half-life of 30 years and in under 2 minutes at that time a single particle emits the power of almost 20 CT scans to the surrounding living tissue of the victim.
The whitewash continues...
