Изотопи на платината

Природната платина (78Pt) се состои од пет стабилни изотопи (192Pt, 194Pt, 195Pt, 196Pt, 19 Pt) и еден многу долговечен (време на полураспад 4,83×10 11 години) радиоизотоп (190Pt). Исто така, познати се 34 вештачки радиоизотопи, од кои најдолготрајниот е 193Pt со време на полураспад од 50 години. Сите други изотопи имаат време на полураспад под една година, повеќето под еден ден. Сите изотопи на платината се или радиоактивни или набљудувачки стабилни, што значи дека се предвидува дека се радиоактивни, но не е забележано вистинско распаѓање. Платината-195 е најзастапениот изотоп.
