Nuclear: not a secure option

Highly radioactive water has leaked from a reactor at Japan's crippled nuclear complex. The plant, which is location 150 miles north of Tokyo has been unstable since the tragic earthquake, which left more than 27,000 people dead or missing across northeast Japan.

Fires, explosions and radiation leaks have repeatedly forced engineers to suspend efforts to stabilize the plant, including on Sunday when radiation levels spiked to 100,000 times above normal in water inside reactor No. 2.

More than 70,000 people have been evacuated from an area within 12 miles of the plant. Samples of rainwater in Massachusetts, Virginia and Pennsylvania have registered “very low” concentrations of radioactive material.

Also, the first signs of radiation have reached the Portuguese island of Azores, in the Atlantic Ocean. The radioactive particles, Xenon 133, traveled a long way from Fukushima - more than 11471 kilometres (7100 miles). Fortunately, its low levels do not cause any harm to human beings.
