25 years after Chernobyl

Today our guest is Stephen Thomas, Professor of Energy Studies, University Of Greenwich. Twenty-five years ago, the explosion at the Chernobyl nuclear power plant in USSR showed how the peaceful atom can be lethal.

Thousands of people were affected and acres of land laid to waste. Decades later, the world thought it had left the tragedy far behind and learnt to deal with nuclear energy. But last month, a tsunami hit an atomic power plant in Japan and fears of a radioactive meltdown resurfaced. So between a nuclear and a non-nuclear world, which do we choose? Here is Professor of Energy Studies from the University of Greenwich Stephen Thomas.
