← ScienceWhich consequence results when medical potassium isotopes decay?
A)An inaccurate PET scan arises✓
B)Osmotic pressure temporarily decreases
C)Tissue damage risk is augmented
D)Membrane hyperpolarization subtly occurs
💡 Explanation
Positron emission isotopes like potassium-40 emit positrons upon decay. Annihilation radiation yields misleading signals leading to errors because electron-positron annihilation creates pairs of detectable photons with different origins, therefore, leading to scan inaccuracies rather than cellular or chemical changes.
