[Thermoluminescent dosimetry studies on absorptive behavior of bones without and with metal implants].
The absorption and scattering in bones with and without metal implants (femur, humerus, ramus mandibulae) is investigated in an automatic water phantom by means of thermoluminescent dosimetry, a semi-conductor detector, and the ionization measuring chamber for different types of radiation. In case of Co-60 gamma radiation a strong back scattering is observed which increases the dose by up to 50% at the side of entry of radiation and reduces the dose at the other side by equally up to 50%. If ultrahard X-radiation of 9 MeV is used under the same conditions, there is considerably less back scattering and an increased forward scattering. Electron radiation of 10 MeV causes a considerable dose increase of up to 45% due to back scattering.
