On 8 April 2014, Japan provided the IAEA with an?update?to current information on radioactivity in seawater at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS).

Japan's Nuclear Regulatory Authority (NRA) continues to closely monitor the radioactivity levels in seawater and reports that levels of Cs-134 and Cs-137 at T-1 and T-2-1, and total Beta at T-2-1 are likely to be elevated temporarily on 4 April 2014. These sampling points near Fukushima NPS are sentinels to assess effects on the environment by incidents including a leakage of contaminated water.

The NRA also provided an update on the?sea area monitoring results?for radioactivity obtained from sea water samples taken at a distance of two to 200 kilometres from TEPCO's Fukushima Daiichi NPS.
