  • Radioactive tracer well logging utilizing bromine
    Patent number: 5164591
    Abstract: Radioactive tracer well logging has typically utilized iodine as a source of gamma rays. Bromine-82 is utilized as the source of gamma radiation in this process. Because bromine-82 emits more energetic gammas and more gammas per decay, less activity is required. Because bromine has a shorter half-life and has less of a tendency to concentrate in a human's thyroid gland than iodine, consequences of incidental releases are less severe.
