Internal Conversion: Why is K-Shell Electron Knocking Out Higher?

[GAGS]

Hi all,
Why the probability of knocking out k-shell electron in internal conversion is higher? Please don't mention here that k-shell is nearer to nucleus.
Thanks

Look at the radial wave functions, K-shell (L = 0) electrons have HIGHER PROBABILITY to be inside the atomic nucleus. The radial wave functions are found in almost any introductory quantum mechanics source.
