This document identifies and describes the potential postclosure pathways of radionuclide release, migration, and exposure from low-level radioactive waste disposal facilities. Each pathway identified is composed of a combination of migration pathways (air, surface water, ground water, food chain) and exposure pathways (direct gamma, inhalation, ingestion, surface contact). The pathway identification is based on a review and evaluation of existing information, and not all pathways presented in the document would necessarily be of importance at a given low-level waste disposal site. This document presents pathways associated with undisturbed (ground water, gas generation), naturally disturbed (erosion, bathtubbing, earth creep, frost heave, plant and animal intruder), and inadvertent intruder (construction, agriculture) scenarios of a low-level waste disposal facility. 20 refs., 1 fig.
