Summary

Radioactive substances were released from the TEPCO Fukushima Daiichi Nuclear Power Station (FDNPS) accident into the environment, beginning on 11 March 2011. A large amount of radioactive material was released into the atmosphere from the three damaged cores and 80% of it was deposited into the ocean. Radioactive materials also discharged directly into the ocean as leaked stagnant water from the reactor housing. River runoff and groundwater discharge can also be considered as minor sources of the FDNPS-derived radioactivity in the ocean.
