BARC-made ‘BARC I-125 Ocu-Prosta seed’ is an ideal choice to treat retinoblastoma and uveal tract melanoma, two forms of rare eye cancers. UPSC has asked many questions from the achievements of Indian Institutes like ISRO, BARC, TIFR etc. Also, under development of Science and Technology, this issue is important. Iodine-125 is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat prostate cancer and brain tumors. BARC scientists produce Iodine 125 in a batch process by irradiating 4 gramme of xenon-124 gas in the Dhruva reactor for a period of 15 days. Xenon -125 produced by the neutron interaction decays into I-125.
