Gregory's ServerInteresting that you don't know this. Coal contains radioactive elements that are released into the air as a result of combustion. In fact, more radiation has been released by burning of coal than all the nuclear accidents in history.
Nuclear waste is a unique problem only when you don't compare it with the waste products from coal plants or dealing with the lifecycle of solar or wind generation. All human activities generate waste, and while nuclear waste is uniquely challenging it is also very small in scale and containment, something that is not true for other waste problems.
