'''[[Radium]]''' ('''88Ra''') tidak memiliki satu pun [[isotop]] yang [[Isotop stabil|stabil]] atau hampir stabil, sehingga demikian [[berat atom standar]]nya tidak dapat diberikan. Isotop radium yang berumur paling panjang dan paling umum adalah 226Ra dengan [[waktu paruh]] tahun. 226Ra terjadi dalam [[Deret radioaktif|rantai peluruhan]] [[Uranium-238|238U]] (sering disebut sebagai [[Deret radioaktif#Deret uranium (atau deret radium)|deret radium]]). Radium memiliki 33 isotop yang diketahui, mulai dari 202Ra hingga 234Ra.

Pada tahun 2013 ditemukan bahwa inti 224Ra berbentuk seperti buah pir. Ini merupakan penemuan pertama dari sebuah inti yang asimetris.
