Comparison of Biological Effectiveness of COMS Eye Plaques with I-125 and Pd-103 Sources Using Equivalent Uniform RBE-Weighted Dose

Authors: Jonathan J. Chen, Alexei V. Chvetsov, Yulun He, Ramesh Rengan, Andrew Stacey, Kent Wallner

Affiliation: University of Washington and Fred Hutchinson Cancer Center, University of Washington

Abstract Preview: Purpose: To show that the RBE of low-energy photon sources used in COMS (Collaborative Ocular Melanoma Study) eye plaques compensates for protracted irradiation and attenuation of low-energy photons i...
