The Radiation Interactions and Dosimetry Group maintains a number of radioactive sources of ⁶⁰Co and ¹³⁷Cs which are useful for instrument calibration, radiation effects studies, and radiation research. These sources range in activity from 10 Ci to 25 kCi and are available for use by qualified researchers in government, industry and academia.
