'''[[폴로늄]]'''은 [[안정 동위 원소]] 없이 원자량 186~227 사이에 33가지의 [[방사성 동위 원소]]로만 구성되어 있다. 폴로늄 동위 원소 중 가장 안정한 것은 <sup>209</sup>Po로 [[반감기]]는 약 103년이나, 천연 동위 원소 중에서 가장 안정한 것은 <sup>210</sup>Po으로 반감기는 138.376일이다.

자연에는 극미량 존재하므로 표준 원자량은 정해져 있지 않으나, 폴로늄의 성질과 관련한 연구는 주로 <sup>210</sup>Po를 통해 이루어졌다<ref name="navercast">{{웹 인용|url=http://navercast.naver.com/contents.nhn?rid=44&contents_id=26350 |제목=퀴리부인이 조국 폴란드에 바친 원소, 폴로늄 |저자=박준우}}</ref>.

== 폴로늄-210 ==
<sup>210</sup>Po은 반감기 138.376일을 거쳐 [[알파 붕괴]]하여 <sup>206</sup>[[납|Pb]]로 붕괴한다. 이때 폴로늄 1mg이 [[방사성 붕괴|붕괴]]하면서 방출하는 [[알파 입자]]의 개수는 <sup>226</sup>[[라듐|Ra]] 5g이 방출하는 알파 입자의 수와 같다.<ref>[http://www-d0.fnal.gov/hardware/cal/lvps_info/engineering/elements.pdf]</ref> 이렇게 방출된 알파 입자는 주변의 공기를 [[들뜬 상태|들뜨게 하여]] 이온화시키므로 주변 공기는 푸르게 보인다. 이처럼 알파 입자를 대량으로 방출하므로 [[인공 위성]]에 사용하는 소형 [[방사성동위원소 열전기 발전기|전력 공급원]]으로 사용하기도 한다. 참고로 1g의 <sup>210</sup>Po은 140[[와트]]의 전력을 발생시킨다.<ref>[http://www.ead.anl.gov/pub/doc/polonium.pdf Polonium] {{웨이백|url=http://www.ead.anl.gov/pub/doc/polonium.pdf# |date=20070703021010 }}, Argonne National Laboratory</ref> 이러한 폴로늄 에너지원은 [[소련]]의 [[루노호트 계획|루노호트]]([[:en:Lunokhod programme|Lunokhod programme]]) 달 탐사 위성이 달의 밤 시간 동안 내부 온도를 유지하도록 하는 용도로 사용되기도 하였다.<ref>Andrew Wilson, ''Solar System Log'', (London:  Jane's Publishing Company Ltd, 1987), p. 64.</ref>

또한, <sup>210</sup>Po은 독성이 매우 강하여 1μg으로 성인 한 명을 죽일 수 있는데 이는 [[시안화 수소]]의 25만 배에 해당하는 독성이다. 2006년에는 전직 [[러시아 연방보안국]](FSB) 출신의 [[러시아]] 요원인 [[알렉산드르 리트비넨코]]를 암살하는데 쓰이기도 하였으며, 2013년 11월에는 전직 [[팔레스타인 해방 기구]]의 초대 수반과 [[팔레스타인 자치 정부]]의 의장을 역임한 [[야세르 아라파트]](2004년 11월 11일 사망)의 시신을 부검한 결과, 그의 죽음에도 <sup>210</sup>Po이 사용된 것으로 추정된다.<ref>{{웹 인용|title=Arafat's death: what is Polonium-210?|url=http://www.aljazeera.com/video/asia-pacific/2012/07/2012746748407858.html|work=[[알 자지라]]|date=2012년 7월 10일}}</ref>
