I spent some time in Belarus near the contamination zone working in an orphanage a decade ago. I did not see children with deformities; what I did see was the huge state neglect of damaged kids who had been left there by alcoholic parents. There were a number of deaf children, however, who could say if this was down to radiation?
In some cases, kids had grandparents outside who did what they could; and the over-worked staff in the orphanage who did their best to care for their welfare were heart-warming.
It was desperately sad. However, I came away with a slightly jaundiced view of the arguments put forward by some Irish aid charities about deformities and radiation. The problems in Belarus is grinding poverty, alcoholism, neglect of its population by its government, and yes, disabilities in the general population.
