Idaho National Laboratory - Idaho Falls, Idaho

What is the Dose Reconstruction Process?

Gather information about area of radiation exposure and assess data
Identify pathways of internal and external exposure
Determine methods of calculation to estimate screening doses and exposures
Develop methods to assess and estimate environmental doses
Determine risk of environmental exposures through selected calculation method
Document reconstruction procedures and results

Fact Sheet:
CDC Research Involving Radiation Releases from the Idaho National Laboratory[PDF-108 Kb]

Overview

During the past 40 years, the Department of Energy has operated and tested more than 50 reactors at the Idaho National Engineering and Environmental Laboratory (INEEL) in southeastern Idaho. Also tested were waste-disposal, fuel processing, and fuel handling facilities. The Radiation Studies Branch started a dose reconstruction study at this site in 1992. The purpose of this research is to identify the release of chemicals and radioactive materials since the site opened and determine the potential health effects of these releases on the community. The CDC and its contractors have conducted a complete document search and created a bibliographic database, Phase I. A subsequent contractor conducted additional searches, plus copied many documents identified in Phase I. This database is available on the Internet.

Project Activities

The CDC has completed preliminary studies of the radionuclide and chemical releases (following are final reports). The National Academy of Sciences has conducted a review of the radionuclide report.
