Radiation safety role in institutional disaster planning

United States Nuclear Regulatory Commission (NRC) materials license applicants (non-nuclear power) must submit spill procedures with their application. While our counterparts in the nuclear power industry historically have concerned themselves with disaster drills and evacuation plans as a result of fire, explosion, or an act of terrorism, other licensees are looking only at minor spills of unsealed radioactive material and only at tile radiation hazard. Beyond NRC regulations, various oversight and accrediting organizations require, or at a minimum encourage, a written disaster plan outlining actions to be taken for events likely to occur in the region of the institution. Some of these organizations require drills to practice implementation of the written plan. On 5 May 1999, Mayo Clinic performed a wide-scale disaster drill involving Rochester City and Olmsted County response organizations, and several Mayo Clinic departments. Planning took several months; the drill took approximately three hours. Participants gathered at several meetings post-drill for "debriefing" sessions to discuss successes, areas for improvement, and lessons learned. There were three overriding lessons learned: critical responders need special identification to allow access to the disaster site; initial victim surveys are for gross contamination only; and access to the potentially contaminated disaster site might take weeks or months following a real event.
