Risk communication is a crucial component of any dose reconstruction or risk assessment. RAC works hard to maintain open communication among all stakeholders for each project and has found this to be particularly important in public studies. We learned early on that public credibility is earned by a commitment to constant public involvement. RAC’s past work on public dose reconstruction studies (Hanford Environmental Dose Reconstruction (HEDR), Fernald Dosimetry Reconstruction Project, Rocky Flats Historical Public Exposures Project, and Cerro Grande Fire Risk Assessment) has provided team members with the technical knowledge and experience working with stakeholders to foster open communication among scientists, decision-makers, and citizen groups. RAC’s policy is simple and consistent: work hard to involve all potentially interested parties in the project early and often; make certain that key research staff, properly trained in public participation, are involved in all public interactions; and respond to stakeholder concerns quickly and positively.
