Das langlebigste Isotop <sup>227</sup>Ac (<a href="/wiki/Halbwertszeit" title="Halbwertszeit">Halbwertszeit</a> 21,8 Jahre) hat zwei <a href="/wiki/Zerfallskanal" title="Zerfallskanal">Zerfallskanäle</a>: es ist ein <a href="/wiki/Alphastrahlung" title="Alphastrahlung">Alpha-</a> und <a href="/wiki/Betastrahlung" title="Betastrahlung">Betastrahler</a>. <sup>227</sup>Ac ist ein Zerfallsprodukt des Uranisotops <sup>235</sup>U und kommt zu einem kleinen Teil in Uranerzen vor. Daraus lassen sich wägbare Mengen <sup>227</sup>Ac gewinnen, die somit ein verhältnismäßig einfaches Studium dieses Elementes ermöglichen. Da sich unter den radioaktiven Zerfallsprodukten einige <a href="/wiki/Gammastrahlung" title="Gammastrahlung">Gammastrahler</a> befinden, sind aber aufwändige Strahlenschutzvorkehrungen nötig. </p> <div class="mw-heading mw-heading2"><h2 id="Verwendung">Verwendung</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Actinium&veaction=edit&section=7" title="Abschnitt bearbeiten: Verwendung" class="mw-editsection-visualeditor"><span>Bearbeiten</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Actinium&action=edit&section=7" title="Quellcode des Abschnitts bearbeiten: Verwendung"><span>Quelltext bearbeiten</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Actinium wird zur Erzeugung von Neutronen eingesetzt, die bei <a href="/wiki/Neutronenaktivierungsanalyse" title="Neutronenaktivierungsanalyse">Aktivierungsanalysen</a> eine Rolle spielen.
