Popis:	The absorbed-dose distributions for bremsstrahlung, incident on a tissue-equivalent phantom, were measured with LiF : Mg,Ti thermoluminescent dosimeters at two insertion device beamlines of the European Synchrotron Radiation Facility (ESRF). The measurements were carried out for two different electron beam energies of 4 and 6 GeV. The corresponding bremsstrahlung spectra and power were measured using a high-resolution lead glass total absorption calorimeter. The results are compared with similar measurements carried out at other facilities. The normalized bremsstrahlung absorbed dose in a cross-sectional area of 100 mm 2 , at a depth of 150 mm of the phantom, was measured as 6.1 and 3.6 kGy h −1 W −1 for the corresponding bremsstrahlung spectra of 4 and 6 GeV.
