Isotop seng

**[[Seng]]** (**<sub>30</sub>Zn**) yang terbentuk secara alami terdiri dari 5 isotop stabil: 64Zn, 66Zn, 67Zn, 68Zn, dan 70Zn dengan 64Zn sebagai yang paling melimpah (48,6% kelimpahan alami). Dua puluh lima radioisotop telah dikarakterisasi dengan yang paling melimpah dan stabil adalah 65Zn dengan waktu paruh 244,26 hari, dan 72Zn dengan waktu paruh 46,5 jam. Semua isotop radioaktif yang tersisa memiliki waktu paruh kurang dari 14 jam dan sebagian besar memiliki waktu paruh kurang dari 1 detik. Unsur ini juga memiliki 10 keadaan meta.

Seng telah diusulkan sebagai bahan "penggaraman" untuk senjata nuklir. Lapisan 64Zn yang diperkaya secara isotop, diiradiasi oleh fluks neutron energi tinggi yang intens dari senjata termonuklir yang meledak, akan berubah menjadi isotop radioaktif 65Zn dengan waktu paruh 244 hari dan menghasilkan sekitar 1,115&nbsp;MeV radiasi gama, secara signifikan meningkatkan radioaktivitas luruhan selama beberapa tahun. Senjata semacam itu tidak diketahui pernah dibuat, diuji, atau digunakan.
