Description

Sensitive low background assay detectors and sample analysis are available for non-destructive direct gamma-ray assay of samples. Neutron activation analysis is also supported by the Facility. In the Building 72 facility, shielded by 1.5 m of low activity concrete sensitivities of 0.5 ppb U, 2.0 ppb Th, 1.0 ppm K, 0.04 pCi/kg 60Co are routinely obtained. For the Facility located in the Sanford Underground Research Facility 50 ppt U, 200 ppt Th, 100 ppb K, and 0.004 pCi/kg are obtained for ~1 kg samples with a two week assay.
