Because it apparently killed between 32 and 43 depending what you read. 31 people died as an immediate result of Chernobyl. Long term radiation from Chernobyl may kill anywhere from 100 to thousands of premature deaths, but I also don't count the continual nuclear and chemical disaster that is a normally operating coal power plant or its contribution to premature deaths, let alone its contribution to climate change. Only the deaths as a direct result of the explosion, just to go a little easier on coal.
