[en] The development and testing of the gel-type ^99mTc generator technology has been going on for several years at the Nuclear Power Institute of China. This generator type has already been licensed by the Ministry of Health. With the co-operation of the IAEA, under Model Project CPR/2/006,it is intended to upgrade and optimise the existing facility for large scale production and continue to improve the generator performance in terms of quality and reliability of its use in nuclear medicine. The expert mission objective was to carry out final laboratory tests to assess the performance of the gel- type ^99mTc, locally produced, as well as to assess the suitability of the corresponding ^99mTc eluate for nuclear medicine studies. In particular, the expert tested the suitability of the ^99mTc for the labelling of sensitive biomolecules and its general performance in a nuclear medicine service
