International Atomic Energy Agency: "Fukushima 4th Discharge Tritium Levels Far Below Japan's Standards"

The International Atomic Energy Agency (IAEA) announced that the concentration of radioactive nuclides in the contaminated water from Fukushima Daiichi Nuclear Power Plant's fourth discharge (referred to as 'treated water' by the Japanese government) was significantly below the standard limits, based on an on-site inspection.

On the 29th (local time), the IAEA stated, "IAEA experts stationed on-site on the 28th, when Tokyo Electric Power Company (TEPCO) began the fourth discharge, independently collected and analyzed samples, confirming that the tritium concentration was far below Japan's operational standard."

They added, "During the previous three discharges, tritium concentrations were also much lower than the standard limits," and "Director General Rafael Grossi plans to visit Japan later this month to inspect the discharge situation."

According to discharge-related data that TEPCO shares with the IAEA in real-time, the tritium concentration in the diluted contaminated water was 254 becquerels (Bq) per liter as of 8:10 PM Japan time on the same day.

The IAEA explained that this figure is even lower than one-fortieth of Japan's operational standard. Japan's operational standard is 1500 Bq/L.

Japan's operational standard is stricter than other international safety standards. The World Health Organization (WHO) sets the tritium concentration guideline for drinking water quality at 10,000 Bq/L.
