[1] WALD, p. 204: “There were a couple of public laws in Michigan, dating as far back as 1953…The Department of Public Health was named the official radiation control agency…The Department of State Police was designated as the coordinator of civil defense activities as if and when the governor proclaimed an emergency…The state of Michigan plan reads with simple eloquence: ‘In the event that an incident occurs which releases radioactive materials in concentrations that may be a public health hazard, this plan will be implemented. Implementation will commence by proclamation of an emergency by the Governor by the Director of the Department of Public Health.’”

Scranton appeared at a news briefing to say that Metropolitan Edison, the plant's owner, had assured the state that ‘everything is under control.’”
