Question 2

a) Meta-Technetium-99 is a radioisotope commonly used in radiopharmaceutical applications. It is obtained from the decay of Molybdenum-99, which is itself produced artificially either by neutron bombardment of a target material or chemically separated from the products of uranium-235 fission. Describe the process by which meta-Technetium-99 may be isolated ready for incorporation into a radiopharmaceutical, starting with the two methods for obtaining Molybednum-99.

b) Fluorine-18 is a radioisotope commonly used in positron emission tomography (PET scans). Describe the process by which Fluorine-18 may be isolated ready for incorporation into a radiopharmaceutical.
