Five million people still live in the areas contaminated with radiation after the explosion at the Chernobyl nuclear power plant on 26 April 1986. Anna and Vasyl Malashenko live in the Ivankiv district of the Kyiv region – an area next to the exclusion zone in Ukraine. A few years after the disaster they moved to Western Ukraine but then came back. Vasyl, who runs a farm on a 70-hectar plot, says he doesn’t feel any radiation, but Anna, who used to work at the local radiological laboratory knows it’s there, “you just don’t see it”.
