On 9 July 2014, Japan provided the IAEA with an update to current information on radioactivity in seawater at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS).
The update shows that all radionuclides (i.e. Cs-134, Cs-137, total Beta and H-3) have remained low and stable from 29 June to 5 July 2014 at the sampling points T-1 and T-2-1. The NRA also provided an update on sea area monitoring results for radioactivity obtained from sea water samples taken at a distance of 2 to 200 kilometres from TEPCO's Fukushima Daiichi NPS.
