Technetium-99m Is Regarded as the "Ideal Radionuclide" Because of Its

Technetium-99m is regarded as the "ideal radionuclide" because of its
1) isomeric energy value of 190 KeV
2) ability to be produced by a generator in the radiopharmacy
3) gamma emissions
4) physical half-life of about 6 hours
5) availability and cost
6) minimal Compton interactions based upon its energy level
7) being blocked by thick lead blocks
8) energy level useful for medical diagnosis
9) beta emissions
10) gamma emissions of 90 KeV
