← ScienceWhich consequence results when metastable Technetium-99m isomers decay?
A)Emission of a gamma photon✓
B)Increased neutron particle emission
C)Spontaneous nuclear self-sustained fission
D)Augmentation of alpha particle production
💡 Explanation
The metastable state decays via isomeric transition releasing energy as a gamma photon, because this process allows the nucleus to reach a lower energy state. Therefore, gamma photons are emitted rather than fission, neutron or alpha particles which require significantly different decay processes.
