Table 3. A comparison of DCFs (ratios of TRAK per seed) between 125I (model: IAI-125A) and 103Pd (model: IAPd-103A) notched COMS plaques with two seeds removed.

The data were normalized to those for a prescription depth of 5 mm. DCF: dose conversion factor, TRAK: total reference air kerma, COMS: Collaborative Ocular Melanoma Study.
