Greenpeace has issued a report that says more than 90-thousand people are likely to die of cancers caused by radiation from the Chernobyl nuclear disaster. That's a far higher figure than a United Nations report that predicted the death toll would be around four thousand.
The differing conclusions underline the contentious uncertainty that remains about the health effects of the world's worst nuclear accident as its 20th anniversary approaches on April 26th.
The Greenpeace report, citing data from Russia, Belarus and Ukraine, suggests the UN report was deliberately misleading.
The UN report had suggested that many of the health problems and complaints in the regions around Chernobyl were connected with unhealthy lifestyles, including heavy drinking and smoking.
