  We consider corrections to the Lamb shift of p-wave atomic states due to the
finite nuclear size (FNS). In other words, these are radiative corrections to
the atomic isotop shift related to FNS. It is shown that the structure of the
corrections is qualitatively different from that for s-wave states. The
perturbation theory expansion for the relative correction for a $p_{1/2}$-state
starts from $\alpha\ln(1/Z\alpha)$-term, while for $s_{1/2}$-states it starts
from $Z\alpha^2$ term. Here $\alpha$ is the fine structure constant and $Z$ is
the nuclear charge. In the present work we calculate the $\alpha$-terms for
$2p$-states, the result for $2p_{1/2}$-state reads
$(8\alpha/9\pi)[\ln(1/(Z\alpha)^2)+0.710]$. Even more interesting are
$p_{3/2}$-states. In this case the ``correction'' is by several orders of
magnitude larger than the ``leading'' FNS shift.
