Abstract Die Radiodensitometrie ist eine Methode zur Bestimmung der Holzdichte anhand der Zellwandstärken der langlebigen Tracheiden des Spätholzes. Röntgenaufnahmen von Holzbohrkernen zeigen das Frühholz hell, das Spätholz dunkel. Anhand der Grauwerte lässt sich eine Dichtekurve ermitteln, die Daten für klimakundliche Analysen liefert.
Radiodensitometry is a method for the analysis of wood density on the basis of the thickness of the cell walls of the durable tracheids of late wood. X-ray radiography of the wooden drilling cores shows the pale early wood and the darker late wood. By means of the grey tones one can identify a density curve which provides data for the climatological analysis.
