Isotop itrium: Perbedaan antara revisi

Revisi terkini sejak 28 Agustus 2026 03.57

Itrium (₃₉Y) yang terbentuk secara alami hanya terdiri dari satu isotop stabil, ⁸⁹Y; oleh karena itu, itrium adalah unsur monoisotop dan mononuklida. Radioisotop yang paling stabil adalah ⁸⁸Y, yang memiliki waktu paruh 106,6 hari dan ⁹¹Y dengan waktu paruh 58,51 hari. Semua isotop lainnya memiliki waktu paruh kurang dari satu hari, kecuali ⁸⁷Y, yang memiliki waktu paruh 79,8 jam, dan ⁹⁰Y, dengan waktu paruh 64 jam. Mode peluruhan yang dominan untuk isotop di bawah ⁸⁹Y yang stabil adalah penangkapan elektron dan untuk isotop di atasnya adalah emisi beta. Tiga puluh lima isotop tidak stabil telah dikarakterisasi.

⁹⁰Y ada dalam kesetimbangan dengan isotop induknya ⁹⁰Sr, yang merupakan produk dari fisi nuklir.
