Zusammenfassung
Neutronen und Protonen sind Elementarteilchen des Atomkerns. Sie sind wesentlich schwerer als die Elektronen, die die Hülle eines Atoms erzeugen. Daher besitzen sie andere physikalische Verhaltensweisen, insbesondere im Falle des Neutrons, das keine elektrische Ladung enthält. Zusätzlich ergeben sich biologische Eigenschaften, die eine höhere Wirksamkeit auf alle lebenden Zellen versprechen und die auch in Zellexperimenten gefunden wird. Diese letztgenannte biologische Komponente, die insbesondere den Neutronen zugeschrieben wird, hat sehr schnell zu einem Einsatz beim Prostatakarzinom geführt. Dieser Tumor ist zum einen durch eine relativ geringe Strahlensensibilität ausgezeichnet, zum anderen ist im wesentlichen die lokale Behandlung angezeigt. Beides zusammen ergibt die Indikation der Protonen (oder allgemein der Ionen) und der Neutronen, allerdings mit unterschiedlichen Wichtungen. Will man die Gründe der Einsatzbemühungen von Neutronen und Protonen verstehen, muß man sich mit der Physik und der Strahlenbiologie beschäftigen.
