Gamma Spectrometry
|
 |
|
Services offered include activity measurements of various long-lived natural and man-made radioisotopes using a Ge(Li) spectrometer. For solids, a 10g dry particulate sample is counted directly. For water and aqueous solutions, elements are pre-concentrated from a 500ml sample. The detection limits listed below assume low total activity.
