Other analytical techniques that have been employed for measuring barium and its compounds in environmental media include x-ray fluorescence spectroscopy (XFS), neutron activation analysis (NAA), scintillation spectroscopy, and spectrography (Boothe and James 1985 Landis and Coons 1954 Larsen 1973 Murata and Noguchi 1974 Oppenheimer et al. 1984). XFS and NAA methods are less sensitive than other available analytical methods for measuring barium or its compounds in environmental media. Scintillation spectroscopy and spectrography are less commonly used to measure barium in the environment relative to other analytical methods.
