In[1]:= ss=Sqrt[a + Sqrt[a]];
Applying the rule radp in ss

In[2]:=radp[ss, {a -> 2}]
Out[2]=Sqrt[Abs[Sqrt[a] + a]]

It didn't work well (it doesn't convert Sqrt[a]), same using two bars (/ /. )
It only works with MapAll

In[3]:=MapAll[radp[#, {a -> 2}]&,ss]
Out[3]=Sqrt[Abs[a + Sqrt[Abs[a]]]]

Is it possible to move for not using MapAll?
Thank you
