- W2187817190 abstract "Abstract Nowadays 99m Tc (the daughter nucleus of 99 Mo) is the main isotope used for medical imaging. Its consumption reaches about 150000 Ci yearly and increases continuously [1]. Traditional technologies for 99 Mo production are based on research fission reactors and are accompanied by the large amount of radioactive waste. Besides, for a calibration of scintillation cameras the isotope 57 Co is commonly used because of the proximity of its gammas energy (122 keV) to 99m Tc one but greater lifetime (270 days). Thus, the elaboration of soft technology for these isotopes seems to be urgent. To obtain 99 Mo the authors proposed the irradiation of liquid target (the natural molybdenum solution in the alkali water solution) with braking photons of high-current electron linac. 57 Co is produced in its turn by irradiation of the Ni plate cooled with water. The geometry and treatment conditions for each targetry system were previously optimized by means of computer analysis. The results of simulation as well as of experimental isotope production using proposed technology are presented." @default.
