In reply to the discussion: Fukushima radioactive waters to hit US any day now [View all]muriel_volestrangler
(104,632 posts)66. Your title: "to hit US any day now"
You don't claim it's already here in the OP. Perhaps you've contradicted yourself somewhere in this thread, and claimed it's already here. Do you think that would give you any more credibility?
What your link says:
The radioactive ocean plume from the 2011 Fukushima nuclear plant disaster will reach the shores of the US within three years from the date of the incident but is likely to be harmless according to new paper in the journal Deep-Sea Research 1.
...
Observers on the west coast of the United States will be able to see a measurable increase in radioactive material three years after the event, said one of the papers authors, Dr Erik van Sebille.
However, people on those coastlines should not be concerned as the concentration of radioactive material quickly drops below World Health Organisation safety levels as soon as it leaves Japanese waters.
Two energetic currents off the Japanese coast the Kuroshio Current and the Kurushio Extension are primarily responsible for accelerating the dilution of the radioactive material, taking it well below WHO safety levels within four months.

What the paper says:
Following the March 2011 Fukushima disaster, large amounts of water contaminated with radionuclides, including Cesium-137, were released into the Pacific Ocean. With a half-life of 30.1 years, Cs-137 has the potential to travel large distances within the ocean. Using an ensemble of regional eddy-resolving simulations, this study investigates the long-term ventilation pathways of the leaked Cs-137 in the North Pacific Ocean. The simulations suggest that the contaminated plume would have been rapidly diluted below 10,000 Bq/m3 by the energetic Kuroshio Current and Kurushio Extension by July 2011. Based on our source function of 22 Bq/m3, which sits at the upper range of the published estimates, waters with Cs-137 concentrations >10 Bq/m3 are projected to reach the northwestern American coast and the Hawaiian archipelago by early 2014. Driven by quasi-zonal oceanic jets, shelf waters north of 45°N experience Cs-137 levels of 1030 Bq/m3 between 2014 and 2020, while the Californian coast is projected to see lower concentrations (1020 Bq/m3) slightly later (20162025).

So, that science you keep on claiming you're paying attention to says it hasn't arrived yet. You've just made up a claim that it's already done so. You've no evidence for it at all; and that's why your posts on this subject are a joke. I think you're the only person to be banned from E&E for being wilfully ignorant.

I noticed you skipped an important part of the 1st sentence: But is likely to be harmless

Can't do scaremongering and say "likely to be harmless" at the same time...nt

Not all ionizing radiation is the same. Alpha and beta particles are easily shielded against.

Maybe the starfish deaths along the Northwest coast are related to it?
