The absorbed dose prcduced in active bone marrow by radium treatment of carcinoma of the cervix was measured in a wax and cork phantom containing a real skeleton and closely resembling the human body with respect to size, shape, density, and atomic nunnber. Certain representative bones of the skeleton were fitted with miniature ionization chambers that measured the radiation dose prcduced by three arrangements of radium in cervix applicators of the Manchester type. The mean absorbed active marrow dose prcduced by radiation from a cervix applicator contaning 87.5 mg of radium was 99.7 rads in forty hours. The mean absorbed dose for the smallest applicator, which contained 50 mg of radium, was 58.7 rads. The integral active marrow dose ranged from 1.04 x 10/sup 5/ gram- rads for the largest applicator to 0.61 x 10/sup 5/ gram-rads for the smallest. All exposures were forty hr each. Measured doses at points A and B in the pelvis and doses calculated by conventional dosRhetry methcds showed a close correlation, attributable to the short distances between these points and the sources.
