Isomeric Transition (gamma decay) Electron capture QUESTION 7 Scattered LoRs in SPECT cannot be formed outside of the body, since: gamma rays must scatter parallel with the collimator. gamma rays must scatter near the source. gamma rays scatter multiple times inside the sample. all scattering events are absorbed. QUESTION 8 Is the parent radioactive half-life same as that for daughter and grand-daughter radionuclides True
