On 6 August 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 27 July to 2 August from measurements obtained at the sampling points T-1 and T-2-1. The Nuclear Regulatory Authority (NRA) of Japan 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.
