    Notes: Die Geschwindigkeit von Feststoffteilchen bei der pneumatischen Förderung oder von Katalysatoren und Wärmeträgern, die in chemischen Anlagen im Kreislauf geführt werden, läßt sich unter ungestörten Betriebsverhältnissen sehr genau messen, wenn einige Teilchen radioaktiv sind. Für die Markierung von keramischem Material eignet sich besonders das Nuclid 140La, das eine harte γ-Strahlung aussendet und eine Halbwertszeit von nur 40,2 h besitzt. Es wird durch Bruttoaktivierung von Lanthan durch Neutronen-Bestrahlung gewonnen. Die Strahlenschutzmaßnahmen sind relativ gering, wenn die Aufenthaltszeiten des Personals auf das Notwendigste beschränkt werden.
