Abstract
A comparison of the dosimetry for high-energy photon beams was carried out between the Phys ikalisch-Technische
Bundesanstalt (PTB), Germany, and the STARDOOR Laboratory of the National Institute for Laser, Plasma and Radiation
Physics (INFLPR), Romania. The comparison was based on the determination of absorbed dose to water for three beam
qualities at PTB. The measurement results, reported as a ratio of the STARDOOR and PTB evaluations of absorbed dose
to water, show good agreement (less than 0.5 % deviation). In this work, the degrees of equivalence between PTB and
STARDOOR have been calculated and the results are expressed in terms of En-numbers according to ISO 13528:2005..
