Universal 99Mo/99mTc generator

Sodium pertechnetate (99mTc) injection is produced by means of a (99Mo/99mTc) generator. Technetium (99mTc) decays with the emission of gamma radiation with a mean energy of 140 keV and a half-life of 6.01 hours to technetium (99Tc) which, in view of its long half-life of 2.13 x 105 years, can be regarded as quasi stable.

The radionuclide generator containing the parent isotope 99Mo, adsorbed on a chromatographic column delivers sodium pertechnetate (99mTc) injection in sterile solution. The 99Mo on the column is in equilibrium with the formed daughter isotope 99mTc. The generators are supplied with the 99Mo activity amounts at activity reference time which deliver the ordered technetium (99mTc) amounts, assuming a 100% theoretical elution yield and 24 hours’ time from previous elution and taking into account that branching ratio of 99Mo is about 87%.
