No detectable amount of tritium has been found in fish samples taken from waters near the crippled Fukushima No. 1 nuclear plant, where the discharge of treated radioactive water into the sea began a month ago, the government said Monday.
Tritium was not detected in the latest sample of two olive flounders caught Sunday, the Fisheries Agency said on its website. The agency has provided almost daily updates since the start of the water release, in a bid to dispel harmful rumors both domestically and internationally about its environmental impact.
The results of the first collected samples were published Aug. 9, before the discharge of treated water from the complex commenced on Aug. 24. The water had been used to cool melted nuclear fuel at the plant but has undergone a treatment process that removes most radionuclides except tritium.
ignorance and paranoia about radioactivity go hand in hand.
i know so many otherwise smart people who lose it on this issue. because they just think any radioactivity = destroy planet forever . completely ignorant to how it actually works, and just think every power plant must eventually chernobyl and that one barrel of nuclear waste is enough to destroy 1000s of miles or something equally absurd.
totally sad.
Yet one litre of oil can contaminate over a million litres of water.
I talked about how water released are usually modeled and risk assessments done in another comment abour the pending release a few weeks ago but I can’t find it.
While I can’t speak for all regulatory bodies, and you could be a shitass and release toxic crap without doing a risk assesmsent, it’s very unlikely that this is the case here, particularly because it’s TREATED water that’s being released. That means they have a treatment system (there’s a fucking rabbit hole and half…) which they are using to treat the water to some acceptable criteria/standard. This mean some sort of modeling and risk calculation has been done otherwise they would have just gone ‘yolo pump the water into the ocean’.
Tritium isn’t toxic, it’s mildly radioactive.
Tritated water is toxic just like heavy water. You’d just have to drink a truly ridiculous amount for it to be toxic, to the point that the radiation is a much bigger problem than the toxicity.
Edit: fully tritated water is actually worse, now that I think about it. The radioactive decay will periodically knock off a hydrogen atom, which makes it very reactive. That’s not what this is though.
Water is toxic, if you drink an only mildly ridiculous amount and don’t get some salt too. I say this having been hospitalized for hyponatremia several years back, due to unwisely drinking plain water instead of anything with salts in it when sick.
Oh for sure, I’m a nurse. Heavy water/tritated water is cytotoxic like a chemotherapy drug however, vs just messing up your osmotic balance. Your proteins conformiational structure from hydrogen bonds can’t function correctly with it and you can’t replicate your DNA/RNA because of the difference in size of the hydrogen and your cells die. Starts with diarrhea, ends with death. You need like a 20% proportion of it to see those effects though, so like I said, truly ridiculous amounts of tritated water. More than the entirety that they’re releasing.
I think most reasonable objections to this were that they would be unable to filter out the actual bioaccumulating radioisotopes from the water and it should’ve been kept in retention. In the end you either trust they will or not. I trust they will.
Water eats beta- and even alpha particles in a small radius. Ionized water even more so.
The sea is vast. A pond is but a drop to the sea.
It wasn’t a decision to be taken lightly, but it was a good gamble.
Nobody’s particularly concerned about the actual radiation of the tritium. It’s just that it is actively picked up by your body and used like any other water with the same biological half life of water at 7 days. It can cause some problems in that time. It’s not really a problem of it getting integrated into anything, since all it’ll do is knock itself off of and destroy whatever it gets incorporated into when it decays.
I don’t understand why people think concentrating it and keeping large quantities on-site is preferable to heavily diluting and releasing it. A giant vat of radioactive water sounds like another disaster waiting to happen.
Because they don’t believe that they’ve removed the heavy metals that end up in the food web and sitting in the littoral area seabed until it’s picked up by lifeforms again. Tritium dilutes, but fission products do not.
Yeah they talk about nuclear waste and how it needs to be stored for so long, without recognizing that fossil fuels spew their waste, including radiation, directly into the atmosphere, where it is causing apocalyptic global warming. Having it in barrels is actually a big plus.
