La mort de Litvinenko provocà la sospita que la mateixa substància també s'hauria pogut utilitzar abans amb fins similars. Així, el setembre del 2004, a <a href="/wiki/Sant_Petersburg" title="Sant Petersburg">Sant Petersburg</a>, morí Roman Tsepov, conseller delegat d’una empresa de seguretat privada. Emmalaltí després d'un viatge de negocis a Moscou i en tres setmanes morí amb símptomes similars als d’una malaltia per radiació, com demostrà l'autòpsia. Després de l'accident de Litvinenko, la mort de Tsepov també es fou atribuïda a la presència de poloni. Se sospita que Letxi Islàmov, conegut com a "Barba", comandant de camp txetxè morí a un hospital de la presó de <a href="/wiki/Volgograd" title="Volgograd">Volgograd</a> el 21 d'abril de 2004, també fou enverinat per poloni, sent transportat a una presó de màxima seguretat a Mordovia. Condemnat per segrest de policies, fou hospitalitzat en estat crític directament des del vagó de trànsit en un dels hospitals de la presó de Volgograd. Començà a perdre els cabells i les ungles i la pell estava coberta de butllofes. Els símptomes eren totalment idèntics als de <a href="/w/index.php?title=Yuri_Shchekochikhin&action=edit&redlink=1" class="new" title="Yuri Shchekochikhin (encara no existeix)">Yuri Shchekochikhin</a>, el diputat de la Duma estatal que morí el 3 de juliol de 2003. També <a href="/wiki/I%C3%A0ssir_Arafat" title="Iàssir Arafat">Iàssir Arafat</a>, líder polític palestí, probablement també fou enverinat pel poloni. El 2012, els investigadors suïssos de l’Institut de Radiofísica (IRA) de Lausana trobaren en algunes de les seves coses personals (el raspall de dents, la roba, etc.) una mica de poloni 210, no gaire, però superior al valor de fons. La sospita era tan greu que el novembre del 2012 s'obrí la tomba d'Arafat i es prengueren mostres de les seves restes per examinar-les. L'octubre de 2013, els experts suïssos provaren la presència de substàncies radioactives a les mostres. La investigació demostrà que el fons de poloni a la costella d’Arafat era de fins a 900 μBq, molt superior al que s’esperava, però la major part està en equilibri amb el seu predecessor a la cadena radioactiva plom 210. Aquest fet indica la possibilitat que el poloni pogués ser d'origen natural i que mai no fos present al cos d'Arafat en quantitats suficients per a la intoxicació.<sup id="cite_ref-:1_12-2" class="reference"><a href="#cite_note-:1-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Càncer_de_pulmó"><span id="C.C3.A0ncer_de_pulm.C3.B3"></span>Càncer de pulmó</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Poloni&action=edit&section=10" title="Modifica la secció: Càncer de pulmó"><span>modifica</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/Fitxer:Cigarette_smoking.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/b/b8/Cigarette_smoking.jpg/250px-Cigarette_smoking.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/b/b8/Cigarette_smoking.jpg/330px-Cigarette_smoking.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/b/b8/Cigarette_smoking.jpg/500px-Cigarette_smoking.jpg 2x" data-file-width="2048" data-file-height="1536" /></a><figcaption>Despreniment de fum en una <a href="/wiki/Cigarreta" title="Cigarreta">cigarreta</a> encesa</figcaption></figure> <p>El 1964 es publicà el primer article científic sobre poloni 210 en el tabac i, en les dècades següents, altres investigacions relacionaren els radioisòtops en <a href="/wiki/Cigarreta" title="Cigarreta">cigarretes</a> amb el <a href="/wiki/C%C3%A0ncer_de_pulm%C3%B3" title="Càncer de pulmó">càncer de pulmó</a> en <a href="/wiki/Tabaquisme" title="Tabaquisme">fumadors</a>.
