Japan confirms low radioactivity in seawater near Fukushima after water release

According to the environment ministry, samples collected from 11 locations near the plant indicated concentrations of the radioactive isotope tritium below the lower limit of detection, which is 7 to 8 becquerels of tritium per liter. The ministry stated that the levels of tritium present would not have an adverse impact on human health or the environment.

The ministry plans to release weekly test results for at least the next three months and will subsequently assess the timing for further disclosures. The tests conducted by Japan's fisheries agency on fish in waters around the plant also did not detect tritium.

Tokyo Electric Power Co (Tepco), the operator of the Fukushima plant, confirmed that seawater near the site contained less than 10 becquerels of tritium per liter, which is well below its self-imposed limit of 700 becquerels and significantly below the World Health Organization's drinking water limit of 10,000 becquerels.

Tepco further stated that there have been no significant changes detected in the seawater conditions since the water release began. The situation continues to be monitored closely amid ongoing concerns about the potential environmental impact of discharging treated water from the Fukushima plant into the ocean.
