Japan nuclear accident

Advice for Australians on exposure to radiation arising from the nuclear accident in Japan

Following the Great East-Japan, or Tohoku earthquake and tsunami on 11 March 2011, a series of engineering design and equipment failures caused severe damage to four of the reactors at the Fukushima Dai-ichi Nuclear Power Plant (NPP). It is the largest nuclear accident since the Chernobyl accident of 1986.

  • In most parts of Japan, including Tokyo, radiation levels are now within the normal range of background radiation. More detailed travel advice for Japan, including the location of any restricted areas, can be found on the smartraveller website.
  • In Australia, ARPANSA has assessed that the impact on the health of people and the environment from the Fukushima Dai-ichi NPP accident is negligible.
  • ARPANSA continues to monitor the situation at the Fukushima Dai-ichi site and will provide further advice if there is a significant change to the situation in Japan.
