An electronic spreadsheet has been developed to estimate the maximum individual and population dose from chronic liquid releases occurring at the Savannah River Site. Environmental pathways include external exposure, resulting from recreational activities on the Savannah River and ingestion of water, fish, and invertebrates of Savannah River origin. Quality assurance principles are applied by protecting the spreadsheet from unauthorized change and providing version number, time and date on each page of output. Improvements have been made to LADTAP II's fish and invertebrate consumption pathway model used to estimate population dose. Build-up of shoreline sediments is assumed to have occurred over the past 40 years, the approximate operating time of the Savannah River Site. Additionally, the swimming dose model has been improved by considering tritium absorption through the skin during submersion. Given a typical annual release, the skin absorption dose dominates the swimming and boating dose to both the maximum individual and population.
