Abstract An application of dual photon absorptiometry for measuring Bone Mineral Content (BMC) and the amount of organic matrix in bones in vitro is described. Dual photon absorptiometry was performed using a153Gd source and a Gammatec GT 50 scanner. Although the method is well known in clinical research of osteoporosis and has previously been described, the fundamental principles of the method are demonstrated graphically as this paper is directed to a new audience. Measurements on 9 sections of autopsy and 11 sections of archaeological femoral bones showed that the sum of measured mineral and measured organic matrix was consistent with the weight of the sections with an accuracy of 1.1. and 3.3. per cent respectively. As a further control of the reliability of the method, nine sections were ashed by heating to 800°C for 14 hours. A high correlation could be demonstrated between BMC and ash-weight as well as between the organic matrix and the loss of weight during heating.
