DuMond spectroscopy is a new technique for the determination of bone mineral density. The instrument consists of an Americium-241 source mounted in an absorber post located on the surface of a sodium iodide detector. The analysis is based on the energy distribution of photons scattered by the tissue. Measurements made using a series of powdered bovine cortical bone and wax mixtures gave an R value of 0.991. Repeated measurements made on a series of calcaneus specimens gave a precision of 0.96%.
