Ataremae, it's going to be radioactive for many many years

6 ( +6 / -0 )

half life of cesium is 30-ish years, so yeah. Entire area if not the prefecture needs to be blocked off. It is the storage site. Let's say a safety factor of 10% so 33 years times 5 half-lives makes it 165 years. 50+25+12.5+ 6.25+3.125= 96.875% reduction

Also it's doubtful that in 165 years or more there will be anyone around still working with nuclear energy. Various multiple nearby villages will have to keep the knowledge for generations so that far into the future it can still be managed to be assessed and reduced by whatever means are available then. Educational lessons of today must survive into the future. Even without computers as a safety measure. Multiple villages so that one earthquake doesn't make this education disappear

This would be on top of additional national education too, but you need specific keepers of the understanding, away from the brown envelopes

Then in 165 to 200 years the area can be saved. For such a well educated country this should be well understood, but sadly this is not the case. It is in their paycheque to not understand it. That mentality has to stop

It’s so strange that the media reports on cesium, strontium etc when the actual fuel rods that power the reactors are made of processed uranium which has a minimum half life of 160,000 years........

ah if that's the case then it'll be up to the next generation of humans since that's about as long as we've been a species!

Hard to say if there will be a next gen though. We'll probably stop the chain with climate change or nuclear war or both. Thus fulfilling Fermi's Paradox

So TEPCO lied??I'm shocked...smh

iodine has very short half life about 8-10 days. Why are they finding it after 7.5 years? Sounds fishy

News flash: readioactive water is still radioactive.

I found an interesting documentary on Netflix. Dark Tours/Japan. I believe it was filmed last year or the year before. Pretty scary stuff.

Doesn't really come as a surprise.

At least they admitted it (this time).

How much more can we expect to come?

6 ( +6 / -0 )

They called it "tritium water," but it actually wasn't.

When they announced the water was safe enough to release in the ocean, I called it, “BS” and it actually is!

Matsumoto said the plant will treat the water further to ensure contamination levels are reduced to allowable limits.

These would be the allowable limits they keep raising, would it not?

Lets all take a minute to reflect on the great leader Abe’s statement to the IOC, “Fukushima dai-ichi is under control.” This is quite obviously a blatant lie.

These ‘temporary’ holding tanks were only designed to last four years. Now, it is 8 years since the disaster with millions of tons of radioactive water stored in ageing tanks, which is growing daily and they still have no idea what to do with it. It would seem the meltdowns were only the first nuclear disaster. The second will come when this water is released into the great garbage patch known as, the Pacific Ocean.

No idea, but let's trust TEPCO. THOUSANDS OF TONS of nuclear waist next to the ocean. Mmm wonder where that's going to go.

Tritium is irradiated hydrogen, which is impossible to remove from water, of course. Furthermore, it will break down and disperse in the ocean with ‘little’ environmental impact if the water is ‘gradually’ released in small amounts. However, they are talking about millions of tons of it and once they start releasing it, it will be like opening a flood gate.

Mmm wonder where that's going to go.

Straight to Hawaii and California.

It depends on the isotope. Iodine-129 has a half life of 15.7 million years.

Then they should release more information about what they found, so we can guess what they are hiding.

@Since1981. Thanks, wish I had Netflix. I’ve only been there twice with my Geiger counter and I can truly say I can back him up. The NZ dude. Can’t watch the doc, but did read some articles about Japanese govt and prefecture reaction. They want to sue Netflix and ban it off the internet.

Of course it is.

It’s one of those problems that doesn’t just go away if you close your eyes and forget about it for a few years - you know, the type the government doesn’t like.
