| Popis: | Barium-137m radioisotope generator of the chromatographic column elution mode based on loading 1.5 g 6-tungstocerate(IV) gel matrix with ~54 kBq of fission-produced 137 Cs is described. The elution performance of the generated 137m Ba radionuclide was investigated as a function of chemical composition of the eluent, flow rate, elution frequency, and age of the generator system. At comparable conditions, 137m Ba eluates with 0.9% NaCl–0.1M HCl eluent had higher elution yields and radionuclidic purity than with 0.1M NH4Cl–0.1M HCl eluent. The generator has been repeatedly eluted for 311 days by passing 4810 ml of the saline eluent (10 ml × 481 elution operations) at a flow rate of 3.0 ml/min. Barium-137m eluates of high and reproducible elution yields, chemical and radionuclidic purities of (8 99.99%) were obtained. |
