On the 25th anniversary of the worst nuclear accident in history, Olga Betko travelled to Chernobyl - in her native Ukraine - to find the people who are living in the "dead zone".

In the last week of April 1986, when the nuclear reactor exploded, showering deadly radiation over the surrounding area, thousands of power station workers and their families were evacuated.

By then many had been contaminated.
