Isotop lutesium

Lutesium (₇₁Lu) yang terbentuk secara alami terdiri dari satu isotop stabil, ¹⁷⁵Lu (97,41% kelimpahan alami), dan satu radioisotop berumur panjang, ¹⁷⁶Lu dengan waktu paruh 3,78 tahun (2,59% kelimpahan alami). Tiga puluh lima radioisotop telah dikarakterisasi, dengan yang paling stabil, selain ¹⁷⁶Lu, adalah ¹⁷⁴Lu dengan waktu paruh 3,31 tahun, dan ¹⁷³Lu dengan waktu paruh 1,37 tahun. Semua isotop radioaktif yang tersisa memiliki waktu paruh kurang dari 9 hari, dan sebagian besar memiliki waktu paruh kurang dari setengah jam. Unsur ini juga memiliki 18 keadaan meta, dengan yang paling stabil adalah ^177mLu (t_1/2 160,4 hari), ^174mLu (t_1/2 142 hari) dan ^178mLu (t_1/2 23,1 menit).

Isotop lutesium memiliki berat atom berkisar mulai dari 149,973 u (¹⁵⁰Lu) hingga 183,961 u (¹⁸⁴Lu). Mode peluruhan utama sebelum isotop stabil yang paling melimpah, ¹⁷⁵Lu, adalah penangkapan elektron (dengan beberapa emisi alfa dan positron), dan mode utama sesudahnya adalah peluruhan beta. Produk peluruhan utama sebelum ¹⁷⁵Lu adalah isotop iterbium, dan produk utama sesudahnya adalah isotop hafnium. Semua isotop lutesium bersifat radioaktif atau, dalam kasus ¹⁷⁵Lu, stabil secara pengamatan, artinya ¹⁷⁵Lu diprediksi bersifat radioaktif tetapi tidak ada peluruhan aktual yang teramati.

Lutesium-177

Lutesium (¹⁷⁷Lu) klorida, yang dijual dengan merek Lumark di antara yang lain, digunakan untuk pelabelan radioaktif obat-obatan lain, baik sebagai terapi anti-kanker atau untuk skintigrafi (pencitraan radio medis). Efek sampingnya yang paling umum adalah anemia (jumlah sel darah merah rendah), trombositopenia (jumlah trombosit darah rendah), leukopenia (jumlah sel darah putih rendah), limfopenia (tingkat limfosit rendah, sebuah jenis sel darah putih tertentu), mual, muntah, dan kerontokan rambut ringan dan sementara.
