Determination of 32 elements in rocks by neutron activation analysis and high resolution gamma-ray spectroscopy

Analysis for trace elements in magnetohydrodynamic (MHD) pilot power plant effluents

“…Rocks are known to be high in many of the same elements, and the activation analysis procedures used for rocks may be suitable for slag and fly ash. Several papers reporting the use of neutron activation for the analysis of rock samples (31)(32)(33)(34)(35)(36)(37)(38) outlined excellent procedures.…”

Determination of trace elements in 13 organic solvents by instrumental neutron activation analysis

“…Determination of radionuclide activity was made by Ge(Li) -ray spectrometry using a Nuclear Data ND 6620 spectrometer. Conversion of -ray spectra to elemental concentrations was carried out by using either spanal or Fourier programs in the Washington State University Amdahl 470 computer (17,18). Corrections for decay during counting (for Tu2 < 10 min), overlapping -ray peaks (e.g., 203Hg/75Se at 280 kev), and neutron flux variations between irradiation levels were made in the FOURIER and spanal programs.…”

Full details of counting procedures and -ray spectra reduction have been presented elsewhere (17,18).…”

Neutron activation techniques for the measurement of trace metals in environmental samples

“…Mercury and zinc can be measured instrumentally utilizing a special coincidence-anticoincidence Ge(Li) detector system (Cooper and Perkins, 1972). Utilizing Ge(Li) diode spectrometry and group radiochemical separations, the pollutant elements of interest can be be measured (Filby et al, 1970;Morrison et al, 1969;Peterson et al, 1969).…”
