Isotop itrium
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.
