AB  - OBJECTIVE: To investigation the shielding property to (125)I of several different 
      prosthetic materials used in clinical when prostheses are used as carriers of 
      (125)I seed in tumor treatment. METHODS: (125)I seeds were taken as the radiation 
      sources to establish a model in vitro and the radiation doses were measured by 
      thermoluminescent dosemeters (TLD). The shielding property of titanium plate, 
      cochrome plate, and poly methyl methacrylate (PMMA) plate were detected, 
      calculated and compared with that of plumbum plate in the control group. RESULTS: 
      The radiation doses of the radiation source at 10 mm distance through the 
      following materials were measured, and the results are 2.805 mGy (0.09 mm thick 
      titanium plate), 1.082 mGy (0.48 thick titanium plate), 0.390 mGy (0.41 mm thick 
      cochrome plate), and 0.261 mGy (0.67 mm's cochrome plate), and 2.885 mGy (1.685 
      mm thick PMMA plate). CONCLUSIONS: The shield property of cochrome is optimal. 
      The poly methyl methacrylate behaves to some extend as a shield to the (125)I 
      seed which can shield the radiation as the effects of plumbum when adopted 
      together with the 0.557 mm's (or more) titanium plate.
