Radiological Electron Microprobe

Housed in EMSL's Radiochemistry Annex, the field emission electron microprobe (EMP) enables chemical analysis and imaging of radionuclides with high spatial resolution in radioactive samples.

The EMP allows non-destructive imaging and compositional elemental analysis of solid-phase materials at high spatial resolution with parts per million sensitivity to aid in analysis of inorganic and radionuclide fate and transport in geochemical systems. Its cathodoluminescence capabilities affords identification of episodic growth in minerals. Initial experiments conducted on natural samples from the Hanford Site provide complementary data to ongoing activities in EMSL's microfluidics and Subsurface Flow and Transport capabilities.
