Imaging techniques (A-level only)

Use of a gamma-emitting radioisotope as a tracer; technetium-99ₘ, iodine-131 and indium-111 and their relevant properties.

The properties should include the radiation emitted, the half-life, the energy of the gamma radiation, the ability for it to be labelled with a compound with an affinity for a particular organ.

The Molybdenum-Technetium generator, its basic use and importance.
