Unit environmental transport assessment of contaminants from Hanford`s past-practice waste sites. Hanford Remedial Action Environmental Impact Statement

Scoring methods and results for qualitative evaluation of public health impacts from the Hanford high-level waste tanks. Integrated Risk Assessment Program

“…The URF values created for this study are based on the modular risk analysis approach developed for the HRA-EIS (Strenge and Chamberlain 1995;Whelm et al 1995). The environmental setting data and exposure factors are those used and reported in the HRA-EIS.…”

RAMS (Risk Analysis - Modular System) methodology

“…Sciences, Inc., to facilitate regional-scale risk analysis. This methodology is described in several documents (Strenge and Chamberlain 1994;Whelan et al 1995). The MRA methodology was developed for regional and site-wide chronic release risk computations involving a large number of release sites and contaminants with different waste forms and for various environmental settings and transport and exposure pathways.…”

“…The unit risk factors developed and utilized by this approach are produced in accordance with the Modular Risk Analysis (MRA) methodology as described in Strenge and Chamberlain (1994) and Whelan et al (1995). The MRA methodology is based on the assumption of linearity between the release site source, the environmental transport, and the impacts at the receptor.…”
