Природниот паладиум (Pd) е составен од шест стабилни изотопи, Pd, Pd, Pd, Pd, Pd и Pd, иако Pd и Pd се теоретски нестабилни. Најстабилни радиоизотопи се Pd со полураспад од 6,5 милиони години, Pd со полураспад од 17 дена и Pd со полураспад од 3,63 денови. Дваесет и три други радиоизотопи се карактеризираат со атомска тежина во опсег од 90,949 u (Pd) до 128,96 u (Pd). Повеќето од нив имаат полураспад што е помал од 30 минути, освен Pd (полураспад: 8,47 часа), Pd (полураспад: 13,7 часа) и Pd (полураспад: 21 часа).
Примарниот распаден режим пред најзастапениот стабилен изотоп, Pd, е електронски зафат, а примарниот режим после е бета-распад . Примарниот распаден производ пред Pd е родиум, а примарниот производ после е среброто.
Ag е распаден производ од Pd и првпат бил откриен во метеоритот Санта Клара од 1978 година. Откривачите сугерираат дека спојувањето и диференцијацијата на малите планети со железо можеби се случиле 10 милиони години по нуклеосинтетички настан. Pd наспроти Ag корелации забележани во телата, кои очигледно се стопени од создавањето на Сончевиот Систем, мора да го одразуваат присуството на краткотрајни нуклиди во раниот Сончев Систем.
