The heart is one of the organs most vulnerable to the effects of radiation, and every year, 6,000 children in the Ukraine are born with genetic heart diseases and defects. One of these defects is the deadly condition known as “Chernobyl Heart.” This is a defect in the heart of children caused by radiation from Chernobyl, and it causes physical holes in the heart of the child, along with a host of other issues.Over 68% of all deaths in Ukraine are due to cardiovascular disease alone and more than 50% of children are not operated on because of lack of facilities and training. Ukraine has an under-five mortality rate of 15%, by comparison to 5% in the UK, and this has been attributed mainly to congenital heart diseases.
