Lihat sumber Isotop praseodimium

'''[[Praseodimium]]''' ('''<sub>59</sub>Pr''') yang terbentuk secara alami hanya terdiri dari satu [[isotop]] [[Isotop stabil|stabil]], <sup>141</sup>Pr; oleh karena itu, praseodimium adalah [[unsur monoisotop]] dan [[Unsur mononuklida|mononuklida]]. Tiga puluh delapan [[Radionuklida|radioisotop]] telah dikarakterisasi dengan yang paling stabil adalah <sup>143</sup>Pr, dengan [[waktu paruh]] 13,57 hari dan <sup>142</sup>Pr, dengan waktu paruh 19,12 jam. Semua isotop [[Peluruhan radioaktif|radioaktif]] yang tersisa memiliki waktu paruh kurang dari 5,985 jam dan sebagian besar memiliki waktu paruh kurang dari 33 detik. Unsur ini juga memiliki 15 [[Isomer nuklir|status meta]] dengan yang paling stabil adalah <sup>138m</sup>Pr (''t''<sub>1/2</sub> 2,12 jam), <sup>142m</sup>Pr (''t''<sub>1/2</sub> 14,6 menit), dan <sup>134m</sup>Pr (''t''<sub>1/2</sub> 11 menit).

Isotop praseodimium memiliki [[Massa atom relatif|berat atom]] berkisar mulai dari 120,955&nbsp;[[Dalton (satuan)|u]] (<sup>121</sup>Pr) hingga 158,955 u (<sup>159</sup>Pr). [[Mode peluruhan]] utama sebelum isotop stabil, <sup>141</sup>Pr, adalah [[penangkapan elektron]] dan mode sesudahnya adalah [[peluruhan beta]]. [[Produk peluruhan]] utama sebelum <sup>141</sup>Pr adalah [[Isotop serium|isotop unsur 58]] ([[serium]]) dan produk utama sesudahnya adalah [[Isotop neodimium|isotop unsur 60]] ([[neodimium]]).
