“…59 Komochkov and Teterev 60 and Borak 61 reported y-spectroscopy measurements performed in the cooling waters of the Dubna 700-MeV Synchrocyclotron and CERN 20-GeV proton synchrotron showing the presence of radioisotopes which were produced by corrosion of machine parts. 60 Co, 58 Co, "Co, "Co, 59 Fe, "Mn, 54 Mn, "Mn, and 22 Na were identified. However, these isotopes are absorbed in the ion exchange resins of the secondary cooling circuit, and the probability of finding them in water released to the environment is negligible, provided the backwash solutions from the filters are isolated from the environment.…”
