인듐 동위 원소

자연계에 존재하는 인듐은 2종으로 113In과 115In이 있다. 안정 동위 원소인 113In은 자연계에서 4.29%, 방사성 동위 원소인 115In은 95.71%로 방사성 동위 원소가 월등히 많다. 하지만 115In의 반감기는 4.41 x 1014 년으로 우주 나이의 3만배를 초과하기 때문에 사실상 안정 동위 원소처럼 취급해도 무방하다. 인공적으로 합성된 인듐의 동위 원소는 97In부터 135In까지이며 이들 중 111In은 의학적 응용에 이용되는데 뇌조, 뇌실, 뇌종양 등의 촬영하여 장기의 상태를 이미지 진단을 하는데 쓰여진다.
