Andrea Bonisoli-Alquati, a willowy Italian biologist, is sitting with a team of his colleagues in one of the very few restaurants in Chernobyl.
In this half-empty dingy canteen, while the speakers blare out euro-pop, Andrea is eating dinner on the first evening of a six day scientific excursion to the 30km exclusion zone that surrounds the infamous Chernobyl nuclear power plant.
He is one of an international team of a dozen researchers who are here to study the ecosystem that was left behind after the 1986 accident."
