Supplemental Operational Guidance for Minimizing Potential Inhalation Doses to Workers and Volunteers at Community Reception Centers and Public Shelters.

In the event of a nuclear explosion in an urban environment, contaminated persons may be directed to Community Reception Centers (CRC) and/or public shelters. This paper is a companion document to a previous paper that addresses the inhalation hazard to workers at a CRC from resuspension of fallout from the evacuees. To limit the inhalation hazard evacuees must be screened to prevent severely contaminated persons from entering a CRC. The suggested screening level is 10,000 dpm cm -2 and rapid methods of screening arriving evacuees are presented. Practical advice is provided on methods that can be used to limit contamination within a CRC. These methods include alterations to heating and cooling systems and the implementation of monitoring strategies to guard against unexpected increases in airborne activity levels.
