γ-ray spectrometry measurements have been carried out at the Cyclotron Laboratory at the Department of Physics of the University of Milan, to evaluate the levels of residual radioactivity after about one year from shut down. Measurements were performed inside the cyclotron and at several points in the accelerator vault and target room, as well as on specific components removed from the beam transport system, on samples of the concrete shields and on residues taken from the cyclotron vacuum chamber. The radionuclides identified and the values of specific activity and dose rate are reported. The results indicate that no particular hazard and waste disposal problems should be encountered at the time of the decommissioning of the facility.

Abstract
γ-ray spectrometry measurements have been carried out at the Cyclotron Laboratory at the Department of Physics of the University of Milan, to evaluate the levels of residual radioactivity after about one year from shut down. Measurements were performed inside the cyclotron and at several points in the accelerator vault and target room, as well as on specific components removed from the beam transport system, on samples of the concrete shields and on residues taken from the cyclotron vacuum chamber. The radionuclides identified and the values of specific activity and dose rate are reported. The results indicate that no particular hazard and waste disposal problems should be encountered at the time of the decommissioning of the facility.
