While nuclear energy does not pollute the environment, it poses the risk of radiation which is harmful to organisms because it causes lethal mutations.
Explanation:
Nuclear fission, for example, releases neutrons and other particles (at very high speeds) that can ionize materials including DNA. This will induce mutations of DNA most of which are usually lethal to organisms. Gamma and X- rays are also produced by fusion reactions and if exposed to organisms also cause mutations on DNA through double stranded breaks. Therefore, the risk of an accident of a nuclear reactor can have immense ramifications on the ecosystems.
