Effective Risk Communication: The Nuclear Regulatory Commission's Guidelines for External Risk Communication [open pdf - 1MB]
"Today's environment for risk communication is complex. Public fear and concern about exposures to hazards have increased along with a corresponding demand for information. The NRC is working to integrate risk analysis into its regulatory activities, and this trend is mirrored in many other government agencies in the United States and abroad. As risk analysis becomes an important dimension of public policy, the need to improve risk communication with internal and external stakeholders is also increasing."
