The objective of this research is to develop a comprehensive evaluation methodology for assessing and weighting the impact of responders’ mental model state related to radiation and risk on their response quality. The first phase of this research utilized an expert focus group to develop an Expected Mental Model State (EMMS) for HAZMAT technicians in RDD incidents. The methodology used the well-established qualitative grounded theory methodology to create an influence diagram architecture to conceptually capture and codify key areas relevant to effective emergency response.

The derived Expected Mental Model State for HAZMAT technicians established the following fourteen key conceptual principle domains: (1) radiation detection equipment, (2) radiation detection operations, (3) response zones, (4) worker protective considerations, (5) public protective considerations, (6) important reference documents, (7) responder confidence level/trust, (8) inherent radiation sentiment origins, (9) core understandings about RDD response, (10) radiation protection principles, (11) radiation dose, (12) radiation characteristics, (13) realistic RDD principles of dispersion of material, and (14) radiation units. Figure 1 in the associated research paper presents a collapsed overview of the EMMS structure, reflecting the conceptual domains; from which 301 specific subtopics emanated.
