← ScienceWhich consequence results when a positron-emitting isotope decays in tissue?
A)Annihilation producing gamma ray photons✓
B)Shielding from external magnetic fields
C)Increased beta particle emission intensity
D)Augmented rate of cellular respiration
💡 Explanation
The positron encounters an electron, leading to matter-antimatter annihilation, which generates two gamma-ray photons, because this conserves energy and momentum; therefore gamma rays are emitted, rather than increased cellular respiration due to minimal positron interactions.
