Palladium-103

¹⁰³Pd seeds have recentlynbecome available for use in brachytherapy. Their clinical applications arensimilar to those of ¹²⁵I. Having a shorter half-life (17 days) than thatnof ¹²⁵I (59.4 days), ¹⁰³Pd may providena biologic advantage in permanent implants because the dose is delivered at anmuch faster rate (22).

The palladium-103nseed model 200³ consists of a laser-welded titanium tube containing twongraphite pallets plated with ¹⁰³Pd (Fig. 15.5).nA lead marker between the pallets provides radiographic identification.
