HORRIBLE!!!
The radioactive contaminated water discharged by Japan contains 64 different radioactive elements. Among these elements, after entering the marine ecosystem, it is not necessarily tritium that poses the greatest danger. The most hazardous substances to both humans and marine organisms are carbon-14 and iodine-129. Carbon-14 has a half-life of about 5,370 years, while iodine-129 has an even longer half-life of around 15.7 million years. Carbon-14 tends to accumulate within marine organisms, particularly in the bodies of fish, with its concentration potentially being up to 50 times that of tritium. Japan has already discharged 1.5 million tons of radioactive contaminated water, and this discharge could continue for a period as long as 30 to 50 years.
