An kuma hada akalla radioisotopes 37, wanda ya kasance a cikin lambar lamba daga 164 zuwa 202. 192Ir, wanda ya faɗi tsakanin isotopes biyu masu kwanciyar hankali, shine mafi kwanciyar hankali na rediyo, tare da rabin rayuwa na kwanaki 73.827, kuma yana samun aikace-aikace a cikin brachytherapy da a cikin radiography na masana'antu, musamman don gwajin ba da lalacewa na walda a cikin ƙarfe a cikin masana'antar mai da iskar gas; Tushen iridium-192 sun shiga cikin haɗarin radiological da yawa. Sauran isotopes guda uku suna da rabin rabi na akalla rana <unk> 188Ir, 189Ir, da 190Ir. Isotopes tare da taro a ƙasa da 191 rushewa ta wasu haɗuwa da β + rushewa, α rushewa, da kuma (rare) fitowar proton, ban da 189Ir, wanda ya rushe ta hanyar kamawar lantarki. Isotopes masu nauyi fiye da 191 suna lalacewa ta hanyar lalacewar β-, kodayake 192Ir kuma yana da ƙananan hanyar lalacewar kamawar electron. Dukkanin isotopes na iridium da aka sani an gano su tsakanin 1934 da 2008, tare da abubuwan da aka gano kwanan nan sune 200-202Ir.
