Principles of public health emergency response for acute environmental, chemical, and radiation incidents

In recent years there have been many environmental, chemical, and radiation disasters that have challenged the emergency preparedness of countries around the globe. This chapter on the principles of public health emergency response for acute environmental, chemical, and radiation incidents summarizes the stages of response to emergencies using a generic ‘all hazards’ framework and a ‘source–pathway–receptor’ risk assessment model which is adaptable to any situation and conforms with international obligations. The stages identified address incident management arrangements for emergency response including international obligations; public health risk assessment; public health risk management techniques and countermeasures; public reassurance in emergencies and incidents and finally the need to identify and publish the lessons from incidents Remembering that before any response can be mounted, the event has to be detected and identified as requiring special action. Detection requires early warning and forecasting to clinical awareness, timely surveillance, and intelligence. A significant number of evidence gaps remain and so detailed documentation and follow-up of future incidents will continue to be needed to fill those gaps and improve emergency preparedness and response in the future. By the use of case studies of some significant environmental, chemical, and radiological incidents and processes the stages of the emergency response are illustrated to facilitate an all hazards approach.
