The mass was named for its wrinkled appearance, which reminded some observers of the wrinkled skin of an elephants leg and foot. Dozens more people contracted serious radiation sickness; some of them later died. Despite the challenges of accidents and war, nuclear energy represents the future, as electricity consumption in the world is growing, he said.
