    Which type of reaction produces the most harmful

    radiation?
    A Fusion reaction Correct Answer Incorrect Answer
    B Fission reaction Correct Answer Incorrect Answer
    C Chemical reaction Correct Answer Incorrect Answer
    D Photo-Chemical reaction Correct Answer Incorrect Answer

    Solution

    Radiation is one of the byproducts of radioactive decay of unstable atomic nuclei. Nuclear fission is the process on which the operation of most nuclear power plants is based. When certain nuclei (for example that of uranium-235) are bombarded with neutrons, the nucleus splits into two smaller nuclei of roughly (though not exactly) equal sizes.
