    Let a radioactive sample undergoes \[\alpha \], \[\beta \] and \[\gamma \]decays (not necessarily in any particular order), then correct order of half-lives of these decays is

    A) \[\alpha >\beta >\gamma \]       

    B)         \[\gamma >\beta >\alpha \]

    C) \[\beta >\alpha >\gamma \]       

    D)        not following any order

    Correct Answer: A

    Solution :

    If half-life of \[\alpha \]-decay is in years then half-life of \[\beta \]-decay is in hours and half-life of \[\gamma \]-decay is in nano-seconds.
