Some medical radioisotopes – nuclides that produce specific forms of radiation used for medical purposes – are obtained as fission products from thermal-neutron-induced fission of ²³⁵U. A particularly important example is technetium-99 m, 99 mTc, which is a meta stable nuclide with a half-life of only 6 h. Research the production and uses of 99mTc: how can be 99mTc produced, separated, transported and used when it has such a short half-life? Why is this particular nuclide well-suited to its application?
