title: In vivo measurement of absolute tissue iodine content by fluorescence excitation.
abstract: A method based on the measurement of fluorescent and transmitted photons has been developed for the quantitative determination of stable iodine concentrations in tissues. The results are independent of the thickness of the material surrounding the measuring site. The method yields an accuracy of better than 3% for both Ge semiconductor and NaI(TI)detector arrangements.
