摘要：

A technique for the measurement of body iron utilising nuclear resonant scattering of gamma rays has been developed. 847 keV photons emitted from a gaseous 56MnCl2 source are resonantly scattered from 56Fe present in the body. Measurement is made using large volume Ge(Li) detectors. The spatial uniformity of activation, the sensitivity of the detection system and the limits of detection have been investigated. Measurements were made on a liver phantom. The resonance scattering technique permits determination of normal levels of Fe in the liver with a radiation dose of 2 rem.
