The 'Nuclear' reference in Nuclear Magnetic Resonance came from the nonradioactive atomic nucleus.

• A. True
• B. False
• C. Not stated
• D. Not applicable

Answer: (A)

NMR centers on the magnetic properties of atomic nuclei. The “Nuclear” in Nuclear Magnetic Resonance refers to the atomic nucleus itself, not to radioactive processes. In practice, NMR uses stable, nonradioactive isotopes such as 1H, 13C, and 15N. A strong external magnetic field aligns nuclear spins, and radiofrequency pulses induce transitions between spin states. The detected signal arises from the precessing nuclear spins, not from radioactive decay, so the technique is non-radioactive. This is why the statement is true.
