Information on radiation for Australians in Japan

This Bulletin is current for Sunday, 27 March 2011.
The Bulletin was issued on Saturday, 26 March 2011, 21:43:21, EST.

This travel bulletin should be read in conjunction with our travel advice for Japan.

The Department of Health and Ageing (DOHA) and Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has issued the following advice on exposure to radiation arising from nuclear incidents in Japan, based on available information and current assessments:


Advice on exposure to radiation arising from nuclear incidents in Japan

Advice for Australians remaining in Japan on food and water precautions, the availability and use of potassium iodide tablets and on appropriate sheltering from radiation if required have been provided today by Australia's Chief Medical Officer and the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).

Extensive advice on these new topics of concern, together with information for people returning from Japan and for use by GPs is contained on this website and is updated regularly.

As a result of new assessments of the situation in Japan, ARPANSA and the Department of Health and Ageing recommended, as a precautionary measure, that Australians within an 80 km zone from the Fukushima nuclear power plant move out of the area.

The US had made a similar recommendation in accordance with the standard guidelines of their Nuclear Regulatory Commission. Their guidelines would require a zone of 80 km (50 miles) around the Fukushima nuclear power plant.

ARPANSA is closely following the safety issues surrounding the Fukushima Dai-ichi site and in particular the current status of the four reactor units and the spent fuel ponds at a number of the reactor units. ARPANSA notes that the Japanese Government has increased the International Nuclear and Radiological Events Scale (INES) rating for this event to INES Level 5 (an accident with wider consequences) for three of the reactor units.

The ARPANSA modelling of airborne radioactive material released from Fukushima Dai-ichi predicts that for Saturday and Sunday any airborne radioactive material will be pushed south-east out to sea. There is a predicted wind shift along the east coast early Monday morning, airborne radioactive material in this region may be pushed to the west towards Tokyo city for a short period of time with a time of arrival Monday afternoon. At around lunchtime Monday there is a predicted wind shift around the reactor site, any airborne radioactive material will then be pushed to the north-west, with possible landfall to the northern part of mainland Japan later that day.

Australians returning home from Japan are highly unlikely to be contaminated or exposed to significant radiation and will not require checks for radioactivity. However, if people wish to seek medical advice they should contact their local GP.

ARPANSA and the Chief Medical Officer advise that iodine tablets are only required when exposed to substantial radiation doses from radioactive iodine. There is no current need for those returning from Japan or those in Japan outside the exclusion Zone to consider the use of potassium iodide tablets at this time.

Discussions continue with medical organisations and state and territory health authorities on these issues. Further information will continue to be provided by the Australian Government as the situation develops.
