Chernobyl scientist says nuclear disaster produced 'invisible enemy'
The horrors of the world’s worst nuclear accident greeted Natalia Manzurova when she arrived in the Ukraine after the 1986 explosion at Chernobyl.

Its sagging, bleeding skin showed evidence of radiation burns. Through clouded eyes, the dog looked sadly at her.
