Positron Emission Tomography Pet Uses Technetium 99 Tc 99 As A Radiation Source For Imaging The Halflife Of Tc 99 I 2 (16.7 KiB) Viewed 16 times
Positron emission tomography (PET) uses Technetium 99 (Tc-99) as a radiation source for imaging. The halflife of Tc-99 is approximately 211,100 years (that's a long time). Why is this long half-life advantageous for use medical imaging? Warning: May contain multiple answers! The radiation particles emitted are safer to humans ODD Radiation levels are relatively stable and constant Radiation levels are relatively low The radioactive waste is easier to store temporarily until it is safe
Match the type of radiation to its corresponding particle. Alpha [Choose] Delta Helium nucleus (2 protons, 2 neutrons) Electron or positron Photon Beta Gamma [Choose
