  • Field analysis of geological samples using delayed neutron activation analysis
    Patent number: 6577697
    Abstract: A system and method for rapidly analyzing elemental abundances in rock or soil samples (14) under field conditions. The system uses a portable neutron source (12) to allow neutron activation analysis of elements having identifiable radioactive decay characteristics. A radiation detector (18) detects radiation released by the sample (14) and provides radiation testing results to an amplifier (26) for computing the concentration of trace elements in the sample with a high degree of accuracy.
    Type: Grant
    Filed: March 19, 2002
    Date of Patent: June 10, 2003
    Assignee: Southwest Research Institute
    Inventors: English C. Pearcy, Mark S. Jarzemba, James R. Weldy
