Japan Fukushima Nuclear Disaster

On 11 March 2011, the Japan earthquake struck approximately 72 km east of the Oshika Peninsula, Japan. At magnitude 9.0, this was the largest earthquake recorded in Japan since records began. The earthquake triggered a tsunami with an estimated height of 14 m at the Fukushima Dai-Ichi site that in less than an hour.

The tsunami resulting 6 m high sea defenses, disabling the shared reactor heat exchangers and diesel generators and breaking the connection to the power grid. With external assistance hindered by flooding, debris and earthquake damage, these serious events led to overheating of the reactors. In the hours and days that followed several hydrogen explosions occurred and the reactor cores of Units 1, 2 and 3 experienced significant to full meltdown.

Fukushima continues to leak hundreds tons of radioactive water into the Pacific Ocean every day. It will continue do so indefinitely as the source of the leak cannot be sealed as it is inaccessible to both humans and robots due to extremely high temperatures.


Impatct on Australia ?

ARPANSA (Australian Radiation Protection and Nuclear Safety Agentcy ) has assessed that the health impact for people living in Australia from the Fukushima Dai-ichi nuclear power plant (NPP) accident is negligible.

Will radiation from Japan reach Australian waters?

It has been estimated that it will take about 5 years (from March 2011) for radioactive materials released to the ocean at Fukushima to reach the north coast of Western Australia, and about 10 to 15 years to reach the east coast of Queensland. By the time it arrives in Australian waters it is expected that the radioactive material will have been diluted to such low levels that they will be difficult to detect.

ARPANSA investigated Contamination of the ocean and atmosphere based on the results of international atmospheric and ocean modelling and daily air monitoring at five locations in Australia.

ARPANSA results and conclusions

No radioactive caesium or iodine from the Fukushima Dai-ichi NPP accident was detected at Australian air monitoring stations. Very low levels of radioactive xenon ( 133 Xe) were detected in Darwin during April 2011, which were assessed to have no impact on the health of any person living in Australia.

No food samples tested by ARPANSA exceeded internationally accepted limits . Some foods had very low levels of contamination. These were targeted for continued testing to ensure the safety of Australian consumers (testing discontinued in 2014).

You may found lots of website rave about water pollution from Fukushima, most of them quoted a chart source from US NOAA ( National Oceanic and Atmospheric Administration).

Chart below indicate Tsunami may effect area, and hight of
tsunami wave. not for pacific ocean contamination.

Althought our Darwin growing facility is not affect by this rumor
but true is true.

Contamination water & fallout

It took just over two years for the radioactive plume from Fukushima, Japan, to travel via ocean currents and reach the shores of North America, researchers say.

A radiation plume from the March, 2011 nuclear accident in Fukushima, Japan took about 2.1 years to travel via ocean currents and ultimately cross the waters of the Pacific Ocean to reach the shores of North America. That's according to to a study published at the end of 2014 (December 29) by the Proceedings of the National Academy of Sciences.

As Kuroshio current clockwise running from Japan --> California -->Hawaii --> Guam --> Japan. This region may accumlated high radiation pollution in long term.

Products from these regions may need take extra care.
