Officially 9,000 people have died from the disaster at Chernobyl, but maybe it's time to...
...meet sisters Irina and Yelena.
They live in an area of Belarus contaminated by the Chernobyl disaster 20 years ago today.
Irina had a brain tumour which had to be removed, which is a pretty rare event.
Yelena has also had a brain tumour, which had to be removed.
Both now have thyroid problems.
Not one penny has been spent on a war on terror of nuclear power.
Greenpeace believe the total count of casualties from the diaster will reach over 90,000 deaths.
It is believed that 20,000 people in the UK have cancer from the fallout on British soil.
The government is "undecided" whether there is a nuclear solution to the world's energy problems.
