A compact solvent extraction based Mo/Tc generator for hospital radiopharmacy.

A compact and portable Mo-Tc generator based on solvent-extraction, mimic to the conventional Mo-Tc alumina column generator is much-needed commodity for use in hospital radiopharmacy setup. The present study includes the development of a portable, simple and low cost Mo/Tc-generator based on MEK solvent extraction technique to obtain a very high concentration of no-carrier added (nca) Tc solution, where low specific activity Mo source is obtained through Mo(n, γ)Mo reaction in a research reactor. The unit is intended for operation under the conditions of medical radiological laboratories. Technical trials showed that the mean time of preparation of sodium [Tc] pertechnetate radiopharmaceutical did not exceed 15 min. The quality and yield of Tc-pertechnetate is upto the mark for formulation of radiopharmaceuticals.
