In preparation for any possible public health emergency related to the current orange (high) threat level, the Centers for Disease Control and Prevention (CDC) is disseminating a series of notices on potential hazards. This is the fourth in a series of four updates. This message focuses on possible chemical threats.
During an orange (high) alert public health agencies and clinicians should be prepared to respond to a terrorist event involving chemical agents. Local and state public health and environmental health officials would be the first called upon to respond to protect the public's health.
During an orange (high) alert public health agencies and clinicians should be prepared to respond to a terrorist event involving radiation or nuclear weapons. Local and state health and radiation control officials would be the first called upon to respond to protect the public's health. The Centers for Disease Control and Prevention (CDC) will be ready to support the states in such an event.
There are several possible scenarios for a radiological terrorist emergency. Radioactive material could be introduced into the food or water supply. A "silent source" of radiation could be placed where people could be exposed (under a subway seat, in a food mall, etc). Conventional weapons could be used to widely disperse radio active materials ("dirty bomb"). A nuclear facility, nuclear waste facility or nuclear reactor could be destroyed by an airplane crash or an explosion. A small nuclear device could be detonated resulting in physical devastation similar to the World Trade Center on September 11, 2001. For information about the types and scope of injuries related to these types of scenarios, please see: http://www.bt.cdc.gov/radiation/emergencyfaq.asp.
An emergency involving radiation would include special challenges for public health responders and clinicians. Treatment of casualties is more difficult because of the contamination and the complications associated with other trauma. People who were not wounded in an immediate attack could still be harmed by exposure to radiation. The debris from the event and other normally harmless materials will be contaminated with radiation. The affected area may be much larger than the immediate scene of the crime. The radiological threat, invisible and uncertain in terms of long-term health impacts, will cause considerable public fear and concern. Finally, the incident will be difficult to manage until appropriate monitoring equipment and well-trained technical individuals are available.
In a radiological or nuclear emergency, a broad public health response involving state, local, and Federal public health agencies will be required. If required, the Department of Energy will establish a Federal Radiological Monitoring and Assessment Center to coordinate the development of radiation monitoring data for use by decision makers. CDC may also join the Food and Drug Administration, the U.S. Department of Agriculture, and the U.S. Environmental Protection Agency to form an Advisory Team for Environment, Food, and Health to assist state and local decision makers. Public health activities that may be required, depending upon the magnitude the event, include the following:
Because these activities will require a collaborative public health effort, state and local health officials may wish to visit CDC's website at http://www.bt.cdc.gov/radiation/index.asp to obtain more information about radiological events and emergency preparedness.
The Federal Response Plan and the Federal Radiological Emergency Response Plan provide information about how federal agencies will coordinate their support for state and local officials.
State and local public health authorities should contact their state radiation control program director for assistance in responding to a radiological or nuclear emergency in their jurisdiction.
For further medical guidance, contact the Radiological Emergency Assistance Center/Training Site, or REAC/TS.
Additional medical guidance can be found at the Department of Homeland Security's Report on Medical Treatment of Radiological Casualties.
