Iodine-125 Half-Life: 59.4 days
Properties: heavy, grayish-black, metallic-looking material
Used in the treatment of prostate cancer, lung cancer, brain cancer
A low energy gamma emitter; maximum energies of 35 keV
The BRACHYSOURCE® iodine-125 implant
Iodine-131Half-life : 8.02 days
Properties: Nonmetallic, purplish-black crystalline solid
Used in brachytherapy or short-range therapy to treat thyroid cancer
Helps treat non-malignant thyroid disorders
Used due to its short half-life and useful beta emission
Strontium-89 & Samarium-153Strontium-89 Half-life: 50 days
Stontium-89 Properties: Silvery metal that rapidly turns yellowish in air
Samarium-153 Half-life: 46.3 hours (1.93days)
Samarium-153 Properties: Reactive, yellowish metal
Used to provide pain relief for metastatic bone disease(cancers that have spread from the original tumor to the bone)
Samarium-153 is used due to its short half-life
Phosphorus-32Half-life: 14.29 days
Properties: Reactive
-White phosphorus: waxy, transparent solid
-Red phosphorus: red powder
-Black phosphorus: looks like graphite powder
Used to control a disease called 'Polycythemia vera', where an excess of red blood cells are produced by the bone marrow.
Used due to its short half-life
Red phosphorus powder
Palladium-103 Half-Life: 16.99 days
Used to manufacture brachytherapy permanent implant seeds
The seeds are primarily used for the treatment of early stage prostate cancer
Used due to its short half-life and low energy emission
