The primary risk of using nuclear power is the health effects of radiation, but other negative effects include potential reactor accidents and radioactive waste. Although radiation exposure is the primary concern, there are other concerns to the community, such as job loss if the reactor is shut down, as well as the ecological damage caused be radioactive waste.
As the events at Chernobyl proved, an accident at a nuclear reactor can be deadly. It can kill and injure tens of thousands of people, causing them to uproot from their homes. It can also cause an area to be completely uninhabitable for years. The issue in other areas is the radioactive waste leaking into the soil and surrounding water sources. Increased radiation leads to increased risk of developing cancer.
