The RTR system and medical response, GIS systems approach. The response to a nuclear or large radiological disaster requires accounting for the physical destruction and the presence of radiation. The damage zones include severe, moderate and light damage, dangerous fallout zones and a zone where time in the zone is monitored. The RTR system⁽¹⁰⁾ includes sites that will form and be determined spontaneously, RTR1, 2 and 3, and others that are predetermined sites (e.g. assembly centres, medical centres [Veterans Administration (VA), National Disaster Medical System (NDMS) and RITN], evacuation centres, community reception centres (CRCs), and Emergency Support Function (ESF) shelters). The coordination of information is accomplished using GeoHEALTH, which is the GIS approach developed by ASPR⁽¹²⁾. (Figure reproduced with permission from Hrdrina et al.⁽¹⁰⁾)
