Isotop polonium

Polonium (₈₄Po) memiliki 42 isotop, semuanya bersifat radioaktif, antara 186 dan 227 nukleon. ²¹⁰Po dengan waktu paruh 138,376 hari memiliki waktu paruh terpanjang dari semua polonium alami. ²⁰⁹Po, dengan waktu paruh 125,2 tahun, memiliki waktu paruh terpanjang dari semua isotop polonium. ²⁰⁹Po dan ²⁰⁸Po (waktu paruh 2,9 tahun) dapat dibuat melalui pemborbardiran proton terhadap bismut di dalam siklotron.
