'''[[Lantanum]]''' ('''<sub>57</sub>La''') yang terbentuk secara alami terdiri dari satu [[isotop]] [[Isotop stabil|stabil]] (<sup>139</sup>La) dan satu isotop [[Peluruhan radioaktif|radioaktif]] (<sup>138</sup>La), dengan isotop yang stabil, <sup>139</sup>La, menjadi yang paling melimpah (99,91% [[Kelimpahan alami unsur|kelimpahan alami]]). Ada 38 [[Radionuklida|radioisotop]] yang telah dikarakterisasi, dengan yang paling stabil adalah <sup>138</sup>La, dengan [[waktu paruh]] 1,02 tahun; <sup>137</sup>La, dengan waktu paruh 60.000 tahun; dan <sup>140</sup>La, dengan waktu paruh 1,6781 hari. Isotop radioaktif yang tersisa memiliki waktu paruh kurang dari satu hari dan sebagian besar memiliki waktu paruh kurang dari 1 menit. Unsur ini juga memiliki 12 [[isomer nuklir]], yang berumur paling panjang adalah <sup>132m</sup>La, dengan waktu paruh 24,3 menit.

Lanthanum stable nucleus

Lantanum (57La) yang terbentuk secara alami terdiri dari satu isotop stabil (139La) dan satu isotop radioaktif (138La), dengan isotop yang stabil, 139La, menjadi yang paling melimpah (99,91% kelimpahan alami). Ada 38 radioisotop yang telah dikarakterisasi, dengan yang paling stabil adalah 138La, dengan waktu paruh 1,02 tahun; 137La, dengan waktu paruh 60.000 tahun; dan 140La, dengan waktu paruh 1,6781 hari. Isotop radioaktif yang tersisa memiliki waktu paruh kurang dari satu hari dan sebagian besar memiliki waktu paruh kurang dari 1 menit. Unsur ini juga memiliki 12 isomer nuklir, yang berumur paling panjang adalah 132mLa, dengan waktu paruh 24,3 menit.

Isotop lantanum memiliki berat atom berkisar dari 116,95 u (117La) hingga 154,96 u (155La).
