Partial half-life

  1. Sep 30, 2015 #1
    1. The problem statement, all variables and given/known data
    What are the partial half of 22Na for decay by
    a)Ec
    b) β+ emission

    2. Relevant equations
    λ=ln2/T1/2

    3. The attempt at a solution
    this what I do
    T1/2 =2.602 Yr

    λ=ln2/2.602

    λ=0.266 yr-1


    what is the difference between
    a)Ec
    b) β+ emission
    there is no Percentage of each decay type.!

    Of course there is. You can look it up in any table of decays or find it online by doing a quick Google search!
