iodine-125
Radioactive halogen variant
Iodine-125 is a radioactive isotope of iodine with a half-life of about 59 days, commonly used in medical applications.
It serves as a radiation source in brachytherapy for treating certain cancers, particularly prostate cancer, where tiny seeds containing the isotope are implanted directly into tumors.
Iodine-125 also has laboratory applications as a tracer in radioimmunoassays and other diagnostic procedures due to its relatively low-energy gamma emissions.
