'''[[Barium]]''' ('''56Ba''') yang terbentuk secara alami adalah campuran dari enam [[isotop]] [[Isotop stabil|stabil]] dan satu isotop [[Nuklida primordial|primordial]] [[radioaktif]] berumur panjang, 130Ba, teridentifikasi sebagai tidak stabil dengan cara geokimia (dari analisis keberadaan [[Produk peluruhan|anak]]nya, [[xenon-130|130Xe]], dalam [[batu]]an) pada tahun 2001. Nuklida ini meluruh melalui [[penangkapan elektron ganda]] (menyerap dua [[elektron]] dan memancarkan dua [[neutrino]]), dengan [[waktu paruh]] (0,5–2,7) tahun (sekitar 1011 kali [[Umur alam semesta|usia alam semesta]]).

Ada total tiga puluh tiga [[Radionuklida|radioisotop]] yang diketahui selain 130Ba. Yang berumur paling panjang adalah 133Ba, yang memiliki waktu paruh 10,51 tahun. Semua radioisotop lain memiliki waktu paruh lebih pendek dari dua minggu. [[Isomer nuklir|Isomer]] yang berumur paling panjang adalah 133mBa, yang memiliki waktu paruh 38,9 jam. 137mBa yang berumur lebih pendek (waktu paruh 2,55 menit) muncul sebagai [[produk peluruhan]] dari [[produk fisi]] umum [[sesium-137|137Cs]].

114Ba diprediksi mengalami [[peluruhan gugus]], memancarkan inti [[Karbon-12|12C]] untuk menghasilkan [[Timah-102|102Sn]]. Namun, peluruhan ini belum teramati; batas atas pada rasio percabangan peluruhan tersebut adalah 0,0034%.
