Partial half-life of Na-22 for electron capture and beta-plus decay

[jije1112]

Homework Statement

What are the partial half of 22Na for decay by
a)Ec
b) β+ emission

Homework Equations

λ=ln2/T1/2

The Attempt at a Solution

this what I do
T1/2 =2.602 Yr

λ=ln2/2.602

λ=0.266 yr-1what is the difference between
a)Ec
b) β+ emission
there is no Percentage of each decay type.!

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!
