Productive capacity

The “TEZLATGICH" Co Ltd has at it’s own disposal two cyclotrons (U-150-II and U-115) with proton beam intensities 1 mA and 0.5 mA., respectively The productive capacity of “TEZLATGICH” makes about 50 Curie of the radioisotope production per year. “Tezlatgich” Co Ltd has a number of technologies by taking such radionuclides as cobalt 57 (57Co), Palladium 103 (103Pd), cadmium 109 (109Cd), which meet the world quality standards.


“TEZLATGICH” Co Ltd guarantees the following parameters of 57Co production, certified by leading World pharmaceutical companies:

The half-decay period of 57Co 271,7 days
Radioisotope 57Co in kind Co(II) in 0,1 М(or 0,5 HCl with concentration (7000 - 7500) mCi/mg
The chemical impurities(Fe, Cu, Ni) 0.02 mg/Ci
Radionuclide impurities <0,1 %
Parking for (1 Ci) 300x300x300 mm3
