When it comes to the destructive power of nuclear energy, we're all aware of the atomic bombs dropped on Hiroshima and Nagasaki, and the meltdown at the Chernobyl power plant.

But did you know about the man who was suffered some of the worst radiation burns in history after an accident at work?

Ouchi worked at Tokaimura Nuclear Power Plant in Japan, a conversion facility which created the nuclear fuel rods for other locations.

30 September, 1999 began as any other work day would for Ouchi and his colleagues Masato Shinohara and Yutaka Yokokawa, who were unaware of how drastically their lives would change forever.

The three men were assigned to a task which required them to mix uranyl nitrate inside a huge metal vat, a task which is extremely dangerous. Unfortunately the men had little experience in handling such a volatile substance and made a miscalculation while mixing the harmful liquids - it would later be revealed the group had used16kg of uranium, 13.6kg over the limit, - which led to disaster.

The men witnessed a shocking blue flash as dangerous amounts of radiation and gamma rays were released into the atmosphere from the uncontrolled reaction - which is not good news.

All three men immediately received high does of radiation, with Yokokawa, who was the furthest away, absorbing 3,000 millisieverts (mSv) of radiation.
