Leichte Erschütterungen des Erdreiches sorgen für eine schnellere Ausbreitung des in der Erde entstehenden Radongases als unter normalen Bedingungen. In unterirdischen Hohlräumen steigt dadurch die Radonkonzentration messbar an.<sup id="cite_ref-21" class="reference"><a href="#cite_note-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> </p><p>Radonmessungen helfen bei der Suche nach Uranerz-<a href="/wiki/Lagerst%C3%A4tte" title="Lagerstätte">Lagerstätten</a>.

Während der Uranprospektion werden auf großen Gebieten einfache, passiv arbeitende Radonmessgeräte auf der Erdoberfläche oder dicht darunter ausgelegt. Überdurchschnittliche Messwerte weisen auf höhere Uran/Radium-Konzentrationen und Bodenporosität und damit auf eine mögliche Lagerstätte hin. Es gibt geologische Prozesse, die Uran und das daraus entstandene Radium voneinander trennen. Deshalb ist der Hinweis auf Uran nicht eindeutig. </p> <div class="mw-heading mw-heading2"><h2 id="Isotope">Isotope</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Radon&veaction=edit&section=5" title="Abschnitt bearbeiten: Isotope" class="mw-editsection-visualeditor"><span>Bearbeiten</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Radon&action=edit&section=5" title="Quellcode des Abschnitts bearbeiten: Isotope"><span>Quelltext bearbeiten</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Es sind 34 <a href="/wiki/Isotop" title="Isotop">Isotope</a> und 4 <a href="/wiki/Kernisomer" class="mw-redirect" title="Kernisomer">Kernisomere</a> des Radons bekannt, die alle radioaktiv sind.
