Many news organizations have reported a widespread rotten-egg smell in southern California Monday. This smell is of course due to sulfur. It was immediately blamed on a fish die-off in the Salton Sea, which has been a dead or near-dead lake for decades.
There has been a criticality in Fukushima last week. Large amounts of krypton-85 were detected in unit 1, a rise in temperature in reactor 2, and large amounts of hydrogen in unit 1 and oxygen in unit 2. We have had fission and radiolysis. Radiolysis is the splitting of water (H2O) into hydrogen and oxygen. There must have been a lot of water involved, because these two gases went into widely separated puffs, units 1 and 3.
In other words, corium has hit a large pool of water.
Sulfur-35 is a radionuclide that is produced from neutrons interacting with seawater. There is a paper published last year that documented sulfur-35 in California air in both aerosol and gas form. Neutrons are emitted in a criticality. What is likely is that corium has encountered seawater and is producing sulfur-35. See the graphic above for the path of this plume.
Sulfur-35 collects in the testes and causes testicular cancer.
What happened was either:
1. There is an underground pool of seawater that is due to the earthquakes opening up a fissure underground where the seawater leaked… OR
2. Corium has entered the ocean directly.
If #2 is true, this might never stop.
