The major problem in harnessing nuclear energy is how to
(A) split nuclei
(B) sustain the reaction
(C) dispose off spent fuel safely
(D) convert nuclear energy into electrical energy
Answer : (C)
The major problem in harnessing nuclear energy is how to dispose off spent fuel safely. The products are radioactive in nature which affects all the organisms who are exposed. Its effects are not confined to one place but to a major distance as the radiations can travel very long distance.
AERB is in charge of the public safety regarding ionizing radiation & nuclear energy.
Therefore option (C) is correct
