Fukashima waste

Could the ocean dilute all the waste water from Fukashima to harmless levels if dispersed properly?

I’m sure it could; the ocean contains almost unfathomable amounts of water. You’d have to tow a lot of that waste water out to a far distance at sea and put a little bit here and there, though.

At some point they will have to get rid of it. They keep building more tanks to hold the water, sounds like an unsustainable plan they are using.

If they just dumped all of into the ocean right now, there’d be a little bit of an increase in radiation around there, but it would go to undetectable levels in days, if not hours. The reason that they don’t do this is not really environmental or based on any science, but based on laws and policy made by people who are not scientists.

Also, the radioactive contamination of the water is mostly fission products, not actinides. The half lives for that is much shorter. Most if not all of the worst stuff is already gone, and what is left will mostly be gone within a couple decades at most.

Well, this is patently wrong, since we can detect the radiation in the water from the US shore. Today.

For the purposes of anyone searching later, I feel obliged to point out that the standard English spelling is Fukushima (cite: Fukushima nuclear disaster - Wikipedia)

Well, to be fair, we do have extremely good detectors, we can still detect the cesium 137 in the environment from nuclear tests half a century ago. So yeah, I meant to say completely insignificant levels.



And that is from 4 years ago. With Cesium 134 having a half life of 2 years, that means that those numbers are at around a quarter of that now.

The rest of my point stands.

There was detectable radiation in the ocean water even before Fukushima. There has always been some radiation in the ocean because radiation is a natural part of the the environment. The question is not whether it is possible to detect radiation in the ocean (the answer is always “yes”) but whether or not those levels pose a significant hazard.
