RESUMO
OBJECTIVE: To compare high-performance liquid chromatography and SepPak as techniques for measuring the radiochemical purity of 99mTc-MAG3. METHODS: Samples of 99mTc-MAG3 (n = 20) with radiochemical purities in the range 43-98% were prepared and analysed by both techniques. RESULTS: The correlation between the results from the two techniques was excellent (r = 1.00) and the differences between the results were not statistically significant (P > 0.05). CONCLUSION: Both techniques are suitable for measuring the radiochemical purity of 99mTc-MAG3.

Under radiation protection legislation in the UK, employers have a duty to maintain appropriate records to account for radioactive materials in their possession and to ensure security of these materials. This applies to radioactive packages, containing items such as technetium generators, which are regularly delivered to hospital nuclear medicine departments. It also applies to the collection of packages, such as those containing used generators for return to the supplier. This article has been written by the professional bodies representing nuclear medicine in the UK in order to provide guidance to hospitals on appropriate procedures that will comply with the legislation. General principles, which should be met by any acceptable protocol, are stated, and practical guidance on how these may be implemented is given. Some example scenarios are outlined.
