Japan says seawater radioactivity below limits near Fukushima (www.channelnewsasia.com)

Tests of seawater near Japan's Fukushima nuclear power plant have not detected any radioactivity, the environment ministry said on Sunday (Aug 27), days after authorities began discharging into the sea treated water used to cool damaged reactors.

Japan started releasing water from the wrecked Fukushima plant into the Pacific Ocean on Thursday, sparking protests within Japan and neighbouring countries, in particular China, which banned aquatic product imports from Japan.

Japan and scientific organisations say the water is safe after being filtered to remove most radioactive elements except for tritium, a radioactive isotope of hydrogen.

As totally expected.

I'm no scientist, but even I know the basics of how it works. And then there's the actual scientists...

[-] Track_Shovel@slrpnk.net 39 points 1 year ago

I talk about it here briefly

It is safe, but 'radio active water release' sells headlines

[-] Redhotkurt@kbin.social -4 points 1 year ago

Fuck off with your Japanese cocksucking behavior.

Wat

[-] Track_Shovel@slrpnk.net 27 points 1 year ago

I'm just as confused as you are. That's not what I wrote.

[-] Redhotkurt@kbin.social 18 points 1 year ago

Frick. I'm a moron. I am so sorry, I replied to the wrong comment.

[-] Track_Shovel@slrpnk.net 9 points 1 year ago

Haha all good

[-] IWantToFuckSpez@kbin.social 10 points 1 year ago

Dude read too much Chinese propaganda

Super safe. We should all do it. Sure even the fish'd appreciate it, you absolutely dumbfuck.

How can you possibly think it is safe?

"Only this, only that, only a bit, only so many rads". They're still dumping their fucking issue into everyone's ocean. Fuck off with your Japanese cocksucking behavior. They're terrorists as far as I'm concerned.

[-] Pogbom@lemmy.world 29 points 1 year ago

Do you have any evidence to go against the tests in the article or are you just rambling?

[-] emperorgormet@sh.itjust.works 22 points 1 year ago

Well it’s been filtered for all radioactive material except tritium and is well below the level of concentration the UN allows for drinking water. They are not detecting any radiation currently and and releasing the water very slowly over 30 years. Did you just not read the article or what?

[-] chaogomu@kbin.social 16 points 1 year ago

You do realize that the ocean has been full of radioactive material for billions of years, right? Uranium oxide is water-soluble. You can literally pull uranium out of ocean water if you know the right chemistry.

Hell, you're currently being exposed to ionizing radiation right this second. So am I, so is every one. Go outside, pick up a handful of dirt and there will be trace amounts of uranium, and likely some thorium. Have a radon detector in your basement? That's radioactive, and comes from the natural decay of uranium.

Do you drink well water? Water-soluble oxides of uranium. Which is why damp basements accumulate radon.

The detected levels of radiation in this discharge water are actually lower than standard background radiation from all the uranium that's literally everywhere.

[-] VonCesaw@lemmy.world 4 points 1 year ago

Then why dont I have superpowers yet

[-] chaogomu@kbin.social 6 points 1 year ago

Little doses of radiation don't lead to superpowers, you need a really big dose. And by superpowers I mean cancer.

[-] nbafantest@lemmy.world 12 points 1 year ago

All water gives off some levels of radiation. Every water drop you've ever drank has.

The levels are very low.

This is no exception.

Please stop posting anti-nuclear nonsense.

[-] claudiop@lemmy.world 11 points 1 year ago

Did it occur to you that most things in nature have radioactive isotopes and that for nuclear reactors we look for the most radioactive bunch, refine them to remove the least radioactive bits and then use them in reactors?

If you reverse that process (well, not really a reversal as you now have different atoms) and re-dillute stuff in nature in a sensible way, you're not going to get anything that is substantially above ambient levels. The oceans are tremendously big and the waste water is already quite treated. One is not going to notice a change in relative terms anywhere on earth unless high-precision equipment is used.

This is not a very-scientifically-accurate comment, but if it was you would not understand so lets keep it like this.

[-] Bipta@kbin.social 9 points 1 year ago

I don't say this lightly: you are an insufferable moron.

[-] Track_Shovel@slrpnk.net 0 points 1 year ago

Lmfao.

[-] Cethin@lemmy.zip 3 points 1 year ago

There is naturally radioactive elements dissolved in water and it doesn't really hurt us. We're bathed in radioactivity all day every day and it doesn't really hurt us. Releasing this water will effectively change nothing. There's a lot of water in the ocean and it's already naturally dissolved radioactive elements, like uranium and other things. How is a tiny bit more going to cause harm?

[-] Track_Shovel@slrpnk.net 2 points 1 year ago

Lol. K.

Wanna bet most people making a scene out of it don't even use sunscreen?

The sun pumps out some amazing stuff. It happens to be the OG nuclear reactor.

[+] allan@lemmy.world -7 points 1 year ago

Sunscreen doesn't protect from gamma rays, does it? It's not really fair to compare radioactivity with sunshine.

[-] Eximius@lemmy.lt 4 points 1 year ago* (last edited 1 year ago)

UV radiation is quite damaging (although part of the popular "summer tan" culture) on its own. However, we also receive higher energy photons (above UV: xray, gamma) as well as some energetic muons from the sun. You get a 4x of a daily dose of radiation if you grab a flight. Around that of an xray. All of which is mostly ignored by people.

You are correct that gamma ray radiation is by far the most damaging radiation. Beta and alpha radiation can be stopped by pieces of paper (or your skin), gamma radiation will go through your house, your car, your wife, hit a dna molecule in your hair follicle, and make that hair follicle permanently gray.

More interestingly, putting the "radioactive" seawater in perspective: tritium fizzles into some beta radiation, of 18kev energy. Assuming, magically, all this (beta radiation) energy was deposited perfectly into your DNA (nearly impossible because it is beta radiation), resulting in maximal damage, in somewhere important and not the dead layer of your skin, doing a tiny calculation we can compute this damage to be that of a photon of 0.07nm wavelength (18 kev), of similar energy used in simple xray imaging (CT imaging uses 5x higher energy). With 10 becquerels / liter, 100 liters of water surrounding you, could inflict a horrible dose of 24 (hours) * 3600 (sec / hour) * 10 x 100 x 18 kev * 1.60218e-16 (Joule / kev) / 70 (kilograms per human) = 3.55958619e-9 Sv in a day

That is a terrifying amount of 3.6 nSv. Almost close to 1/20 that of a banana you eat (I am not joking, just smiling heavily).

Fun facts: https://xkcd.com/radiation/

The fact that people talk about radioactivity in this news, and chinese being angry and the world going apeshit is...... unfathomable.

[-] VonCesaw@lemmy.world 19 points 1 year ago

The elites dont want you to know this but the Godzillas in the ocean are free you can take them home I have 458 Godzillas

[-] sin_free_for_00_days@sopuli.xyz 15 points 1 year ago

On one hand it's weird how people are so upset about this, on the other these morons were talking about radioactive fallout hitting the US right after the tsunami hit. They aren't the brightest bulbs.

[-] freeman@lemmy.pub 14 points 1 year ago

Yeah it mostly seems reactionary nonsense.

Like you ca. swim at the top of a pool in a tractor coolant tank. Water is very cool at diffusing radioactivity (if that’s the right term, it’s probably not).

Heck we have legit crashed nuclear subs at the bottom of the ocean, and places we have just straight dumped waste much more potent than this water.

[-] cyborganism@lemmy.ca 4 points 1 year ago

It's only at 4.3 rads. It's not ideal, but it's okay.

[-] Schmuppes@lemmy.world 1 points 1 year ago

Take some Rad-Way from time to time.

[-] Chetzemoka@kbin.social 1 points 1 year ago

The solution to pollution is dilution ¯\_(ツ)_/¯

[-] schroedingershat@lemmy.world -2 points 1 year ago

Because no human activity could ever have effects that accumulate at the macro scale. All that plastic has been successfully diluted and SO2, CO, CFCs and CO2 are all harmless once released.

[-] Chetzemoka@kbin.social 1 points 1 year ago

(I mean, we're talking about radioactive water from one nuclear power plant. I'm pretty sure the adage applies in this case.)
