The absolute bremsstrahlung intensity generated by the interaction of the electron beam of the Adone storage ring of LNF has been measured as a function of angle and distance from the emitting straight section. Absorbed doses have been measured at variuos distances from the straight section by means of thermoluminescent dosimeters for a 1.5 GeV electron beam. The experiment has been simulated using the most recent version of the FLUKA code which includes a very accurate treatment of bremstrahlung. In spite of the considerable uncertainties on the experimental value of the pressure, it has been found that the computed results are in satisfactory agreement with the results of the measurements. The experiment provided also evidence for the angular distribution of the bremstrahlung intensity at energies in excess of 1 GeV.
