Physics

TECHNETIUM

1. 99 Tc m is used in 90% of radionuclide imaging.

2. Emits 140 keV gamma rays (undergoes beta - decay and subsequent isomeric transition ).

3. Short half life of 6 hours.

4. Produced on site by beta - decay, from its parent molybdenum in a technetium generator.



5. Other radionuclides common to diagnostic nuclear medicine imaging include 123 I, 67 Ga, 111 In, 133 Xe, and 201 Tl.
