Abstract
Ytterbium-169 is a promising source for future high dose rate (HDR) brachytherapy procedures. The lower energy gamma rays emitted by the radionuclide are readily shielded by gold foils as experimentally demonstrated using Gafchromic films. The dose from a ytterbium-169 source was decreased approximately 30% at 1, 2, and 3 centimeters as a result of shielding with 100 microns of gold. This is approximately three times more effective than shielding an iridium-192 source, which had a dose reduction of approximately 10% as a result of the 100 microns of gold.
