'''비스무트 동위 원소'''({{llang|en|isotopes of bismuth}})는 [[자연계]]에 6종이 존재하며 이들 중 <sup>209</sup>Bi가 100% 가까이 존재한다. 핵자 수 210, 211, 212, 214, 215는 [[우라늄]]과 [[토륨]]의 붕괴 사슬 과정에서 생성되는 동위 원소로 자연계에 극히 미량으로 존재한다.

[[비스무트]]는 [[안정 동위 원소]]가 존재하지 않는다. 하지만 <sup>209</sup>Bi의 [[반감기]]는 1.9 x 10<sup>19</sup>년을 초과하기 때문에 안정 동위 원소로 취급하고 있다. 이는 [[우주의 나이]]의 14억배나 된다.

== 비스무트-209 ==
<sup>209</sup>Bi의 반감기는 1900경년에 이른다. 이 정도의 시간이면 영원이라고 해도 무방하므로 안정 동위 원소들 중 가장 무겁고 붕괴 계열 중 [[붕괴 계열#넵투늄 계열|넵투늄 계열]]의 최종 붕괴 생성물로 알려져 있다.
중성자 흡수율이 극도로 낮아 중성자를 거의 흡수하지 않기 때문에 [[4세대 원자로]]의 냉각제로 부분적이나마 주목받고 있다. 다만 [[중성자]]를 한 개 흡수하면 [[폴로늄-210]]으로 변환되기 때문에 꺼려지기도 하는 면이 있다. (폴로늄-210은 반감기가 짧아 초극미량으로도 방사능이 매우 강하다.)

자연계의 비스무트 동위 원소 중 100% 존재하고 있다.

독성이 없는 큰 장점 때문에 차세대 [[초전도체]]의 연료로써 많이 이용되고 있으며 철강 산업에서 합금으로 이용되며, 의약품으로도 이용한다. 이러한 큰 장점과 중요한 이용가치로 인해 [[지각 (지질학)|지각]]에 불과 48ppb밖에 존재하지 않음에도 불구하고 전세계에서 8500톤이나 생산되어 매우 중요한 동위체로 자리잡은 원소이다.

== 비스무트-210 ==
붕괴 계열 중 [[붕괴 계열#라듐 계열 (우라늄 계열)|라듐 계열]]에 해당하는 동위 원소로 반감기가 짧아 자연계에 극미량 존재하는 붕괴사슬의 한 동위체이다.

== 비스무트-212 ==
붕괴 계열 중 [[붕괴 계열#토륨 계열|토륨 계열]]에 해당하는 극미량 존재하는 붕괴 사슬의 한 동위체이다. 비스무트-212 중 64%는 탈륨-208로 붕괴되며 탈륨-208은 강한 감마선을 내뿜고 납-208로 붕괴되기 된다. 이로 인해 토륨 사이클에서 생성되는 우라늄-232는 핵전지의 연료가 아닌 핵 폐기물로 분류케되는 원인의 동위체이다.
