Japan started releasing treated radioactive water from the wrecked Fukushima nuclear power plant into the Pacific Ocean on Thursday, a polarising move that prompted China to announce an immediate blanket ban on all aquatic products from Japan.
China is “highly concerned about the risk of radioactive contamination brought by… Japan’s food and agricultural products,” the customs bureau said in a statement.
The Japanese government signed off on the plan two years ago and it was given a green light by the U.N. nuclear watchdog last month. The discharge is a key step in decommissioning the Fukushima Daiichi plant after it was destroyed by a tsunami in 2011.
My understanding is that they can chemically remove damn near everything except the tritium. It’s because the tritium hydrogen atoms aren’t in the place of regular hydrogen in H2O.
So essentially they can’t filter the water out of the water, if that makes sense.
