The WHO don't exactly agree with you.
From your link:
"5 SEPTEMBER 2005 | GENEVA - A total of up to 4000 people could eventually die of radiation exposure from the Chernobyl nuclear power plant (NPP) accident nearly 20 years ago, an international team of more than 100 scientists has concluded."
I have concluded I COULD eventually die from sexual exhaustion occasioned by a three way with Taylor Swift and Kylie Minogue. That doesn't mean it WILL happen.
Their own numbers put the death toll at fewer than 50 people to date - you can expect most of those to be the poor first responders. How many decades ago was Chernobyl now? Peanut allergies have probably killed more Belarussions, AIDS too, and suicide certainly.
The fact is that the risk to the general populace from nuclear power is extremely low. More people have probably died due to premature respiratory illness in Xian in China (home of the terracota warriors) than will have died due to nuclear power globally in the history of nuclear power. Coal fired power being the main cause of pollution in Xian; the locals all come out when it rains at night as its the only way to see the stars.
