Sensitive laboratory technique for both qualitative and quantitative analysis of elements in samples. Target nuclei are bombarded with neutron beams to start nuclear reactions which emit characteristic gamma ray radiations.
Services available at the Geological Survey TRIGA Reactor (GSTR) site in Denver with information on irradiation, neutron activation analysis, fission track radiography, and geochronology and tours of the facility.
