Fission is a breaking of atom, into 2 pieces, with the release of energy.
So all the K40 Radioactive Potassium in the Oceans is from a primordial source, perhaps the "big bang", or just God if you wish.
Ocean critters have been swimming and reproducing in 11,800 Bq/M3 and slightly higher for hundreds of millions of years. Some in the turtle family sit on the bottom often, and live for 300 years.
And things seems to work out fine in the Kenny Boy "Radioactive Ocean"
There are attacks on the ocean from many directions. Chemicals, Acoustic, pH (acidity), Mining, Over Fishing. The "blob" being 1 deg F higher seems kind of like a joke to me.
But "we" just recently blasted 400,000 pounds of radiation and heavy metals into the ocean via Fukushima, and NO US GOVERNMENT FUNDING is researching this? And 1500 plus days of minimal 300 tons of radioactive water, admittedly leaking into the ocean from the underground river that the Fukushima plant was built on....and no one is researching this?
HINT: it is not Domoic Acid that is doing most of the dying sea life in, only 1 or 2% is Domoic acid.
Review and ask any questions
Geek alert -- this is kind of important, BECAUSE it creates a problem for the nuclear industry, and especially for used fuel "processing". This three way fission produces a lot more tritium in reactors than was predicted....another problem for the power reactor "people".
For those that want to dive down the rabbit hole even further, there is another type of fission called
ternary fission, which simply means "three way fission"
This is still a pretty vague science, with a 100% uncertainty on how often it happens, but it is small.....either .2% up to .4%. So pretty much ANY molecular weight products can be created when this happens, but for the most part the larger fragments still follow the same double hump "guide".
But in reality 90% of the small fragments are Helium 4
and 7% are triton (tritium)
much of the rest is Helium 6 which almost immediately turns into Lithium 6
Cross-section data for 33 nuclides have been obtained radiochemically and used to construct a mass-yield curve for the fission of
