Japan is about to start releasing treated wastewater from the Fukushima nuclear power plant into the Pacific Ocean. At first, this sounds like a terrible idea, but in fact, it is sensible and safe. Similar releases have occurred around the world for decades, and nothing bad has ever happened. 

The radioactivity in the Fukushima water is almost entirely tritium, a form of hydrogen. For scale, the Pacific Ocean contains 8,400 grams of pure tritium, while Japan will release 0.06 grams of tritium every year. The minuscule amount of extra radiation won’t make the tiniest jot of difference. A lifetime's worth of seafood caught a few kilometres from the ocean outlet has the tritium radiation equivalent of one bite of a banana. 

In South Korea and Pacific Rim nations, a disinformation campaign has whipped the public into a frenzy about the release. In truth, almost everything is radioactive, including the Pacific Ocean, where tritium accounts for a modest 0.04% of total radioactivity. Increasing this tiny amount by a tiny amount is hardly end-of-the-world stuff. It is time for informed scientists to stand up and be counted, and face down the doomsayers.
