The aim of this work is to compare results of the densitometric evaluation techniques used in the Central Research Institute for Physics Budapes: (KFKI) to that performed at the Central Institute of Isotope and Radiation Research Leipzig (ZfI) on purpose to improve the resolution and precision respectively. Optical density distributions along defined lines of the autoradiograms are measured by a JOYCE LOEBL Double Beam Recording Microdensitometer type MK-III.CS in the KFKI laboratory and by a modified ZEISS-Schnellphotometer G2 in the ZfI laboratory. A full screen imaging of the autoradiograms may be performed by means of the DENSITRON 4 image analyzer developed in ZfI. Results obtained in this work will be discussed.
