> In addition to high levels of hazardous radionuclides such as strontium-90,
TEPCO on 27 August 2020 acknowledged for the first time the presence of
high levels of carbon-14 in the contaminated tank water
- Reason077 4y agoThe idea is that the strontium-90, carbon-14, etc can be filtered out, leaving just the tritiated water to be discharged.
- pera 4y agoAccording to the article I cited: > Greenpeace said it had confirmed with Tepco that the system was not designed to remove carbon-14 Maybe there are updates on this matter but I couldn't find anything online.
- Reason077 4y agoSounds like you're right about the carbon-14: "C-14 also cannot be removed by ALPS, but its concentration is far lower than its regulatory standard for discharge."

- tablespoon 4y agoIs the carbon-14 an actual health concern, or just a PITA for future archeologists?
- gus_massa 4y agoNitpicking: The archeologist already have tables to fix variations of the C_14 vs C_12 in the past https://en.wikipedia.org/wiki/Radiocarbon_calibration https://en.wikipedia.org/wiki/Radiocarbon_calibration
- xyzzy21 4y agoExcept if you consider the "entropy" of doing that, you have an enormous amount of energy inputs required.
