[Radiation monitoring in the area of metallic dental replacement during cobalt 60 gamma radiation and in electron radiation of oral tumors].

In the radiotherapy of malignant tumors of the oral cavity, the exact distribution of radiation dosage in the neighborhood of metallic dental replacement has been uncertain so far. Many authors therefore asked that crowns and bridges be removed before radiotherapy. By means of lithium fluoride thermo-luminescence dosimetry, punctate measurements of doses are possible for the first time. In view of the dose values obtained, removal of metallic dental replacement before the beginning of radiotherapy as a prophylactic measure to prevent radioosteomyelitis appears not to be necessary.
