Isotop indium

Indium (49In) terdiri dari dua nuklida primordial, dengan yang paling umum (~ 95,7%), 115In, terukur memiliki radioaktivitas meskipun lemah. Peluruhan spin-terlarangnya memiliki waktu paruh 4,41 tahun.

Isotop yang stabil, 113In, hanya 4,3% dari total indium alami. Di antara unsur-unsur dengan isotop stabil yang diketahui, hanya telurium dan renium yang serupa terjadi dengan isotop stabil dalam kelimpahan yang lebih rendah daripada isotop radioaktif berumur panjang. Selain 115In, radioisotop yang berumur panjang adalah 111In, dengan waktu paruh 2,8047 hari. Semua radioisotop lain memiliki waktu paruh kurang dari satu hari. Unsur ini juga memiliki 47 isomer, yang paling lama hidup adalah 114m1In, dengan waktu paruh 49,51 hari. Semua keadaan meta lainnya memiliki waktu paruh kurang dari satu hari, sebagian besar kurang dari satu jam, dan banyak yang terukur dalam milidetik atau kurang.

111In digunakan secara medis dalam pencitraan nuklir, sebagai tag nuklida pelacak radioaktif untuk lokalisasi kamera gama dari radiofarmasi protein, seperti oktreotida berlabel 111In, yang mengikat reseptor pada tumor endokrin tertentu (pemindaian oktreotida). Indium-111 juga digunakan dalam pemindaian sel darah putih indium, yang menggunakan teknik medis nuklir untuk mencari infeksi tersembunyi.
