Fish and wildlife that inhabit the Columbia River and Hanford Site are monitored for radioactive contaminants for several reasons. Wildlife has access to areas of the site that contain radioactive or chemical contamination, and fish can be exposed to contamination entering the river along the shoreline. Fish and some wildlife species exposed to Hanford contaminants might be harvested for food and may potentially contribute to offsite public exposure. In addition, detection of contaminants in wildlife may indicate that wildlife are entering contaminated areas or that materials are moving out of contaminated areas.
Samples are collected at various locations annually. Bone and muscle samples are analyzed to evaluate radiation levels.
Detailed information on fish and wildlife surveillance is available in the 2006 Hanford Site Environmental Report.
