IAEA experts sampled seawater from Kitaizumi Beach in Minamisoma, Japan, and confirmed the tritium concentration is far below Japan’s operational limit.

International Atomic Energy Agency (IAEA) experts confirmed on Tuesday that the tritium concentration in seawater samples taken from a popular beach destination in the city of Minamisoma in the Fukushima Prefecture is far below Japan’s operational limit.

Seawater from Kitaizumi Beach in Minamisoma was sampled on 4 July by IAEA experts stationed at the Agency’s office at the site of the Fukushima Daiichi Nuclear Power Station (FDNPS), following consultation with the Government of Japan. The IAEA confirmed that the tritium concentration in the seawater from Kitaizumi Beach is far below the operational limit of 1500 becquerels per litre and is in line with international safety standards. Tritium exists naturally and is found in rainwater, seawater, tap water and inside the human body.

Minamisoma is about 30 kilometres north of the FDNPS, where Tokyo Electric Power Company (TEPCO) has been discharging diluted ALPS-treated water since August 2023. TEPCO began discharging the seventh batch of ALPS-treated water, which is approximately 7800 cubic metres of water, on 28 June and plans to conduct a series of controlled discharges into the sea over a period of decades. The IAEA has earlier confirmed that the tritium concentrations in the seven batches of ALPS-treated water were far below operational limits.
