Environmental Radioactivity Section Objectives

To support metrology improvements in the radiochemistry community through research and development of low-level radionuclide Standard Reference Materials (SRM's) and measurement quality assurance.

Goals and Program Summaries

  • Provide environmental natural-matrix SRM's for validation of radiochemical methods.

  • Provide traceability testing of common environmental and bioassay materials to the low-level radiochemistry community.

  • Develop a standard sequential extraction protocol for use in the environmental assessment community. The sequential extraction methodology provides unique insight into the geochemical partitioning of radionuclides in soils and sediments.
