Radiation emergencies that potentially could occur in University facilities fall into 5 general categories:

This list is not exhaustive. The ordering suggests but does not ensure a gradation from less to more serious; any of these incidents could have serious consequences and could require immediate action. See the Radiation Safety Handbook (pdf) for the full text and instructions pertaining to radiation emergencies. 

The general rule is to take whatever immediate action is required to stop or reduce the exposure, and call for help. Immediate action could be righting a container, using an eyewash, turning off an x-ray beam, or removing contaminated clothing. Tell colleagues in the immediate area what has happened. An important caveat is that your initial response should not place anyone--including yourself--in greater jeopardy. Announcements should be loud and clear so there is no misunderstanding about what is occurring.

Emergency Postings

Laboratories are required to maintain an emergency posting outside of the laboratory by the door on which are listed the names and phone numbers of primary and secondary contacts who can be called by the police or other emergency responders. They should be persons who know what is going on in the laboratory and can provide information about potentially hazardous materials or situations. Please take the time now to review the information on your emergency posting. Make sure it is current, accurate and legible.
