  • Patent number: 4016418
    Abstract: A method for determining the source strength of a radioactive sample such as iodine-125 or cobalt-60, which emit pairs of quanta of radiation in coincidence, or near coincidence, and for determining the counting efficiency of a detection instrument analyzing such samples. A first counting channel is used to count events attributable to single quanta, a second counting channel is used to count events attributable to coincident pairs of quanta, and the sample source strength is computed from the results of measurement in these two counting channels. Then, the counting efficiency in a third channel designed for subsequent use in analyzing test samples may be determined from the counting of events in the third channel.
