How to draw a circle intersecting a shaded non-uniform shape using tikz?

I am trying to draw this picture:

circle intersecting a shaded non-uniform shape

I have tried a lot of things, like defining this

newcommandirregularcircle[2]{

    pgfextra {pgfmathsetmacrolen{(#1)+rand*(#2)}}

    +(0:len pt)

    foreach a in {10,20,...,120}{

        pgfextra {pgfmathsetmacrolen{(#1)+rand*(#2)}}

        -- +(a:len pt)

    } -- cycle

}

But it don't give a figure that can be between the x-axis and the circle, and I don't know how to do this. Thanks.

One possibility is tp build up a random list and plots a smooth curve through it.

documentclass[tikz,border=3.14mm]{standalone}

usetikzlibrary{patterns}

begin{document}

begin{tikzpicture}

 pgfmathsetseed{9}

 foreach X in {0,...,11}

 {ifnumX=0

   pgfmathsetmacro{myradius}{2}

   xdefmyLst{myradius}

  else

   pgfmathsetmacro{myradius}{{myLst}[X-1]+0.5*(rnd-0.5)}

   xdefmyLst{myLst,myradius}

  fi}

 xdefmyLst{myLst,2} 

 draw[pattern=north east lines] (2,0) -- 

 plot[smooth,variable=x,samples at={0,...,12}] 

  ([xshift=2cm]-x*10:{{myLst}[x]}) -- (-60:2) arc(-60:0:2);

 draw (120:2) arc (120:-120:2);

 draw[-latex] (0,0) -- (5,0);

 draw[dashed] (2,0) -- (2,-pi);

 draw (2,0) -- ++ (-120:pi);

 draw[latex-latex] (2,0) + (-120:2.7) arc(-120:-90:2.7) node[midway,below]{$mu$};

 draw[-latex] (2,0) -- ++ (-45:1) node[pos=1.2]{$z$};

end{tikzpicture}

end{document}

@Sebastiano I do not understand the comment. But please do not expect me to update my answer to add a U, there are several other things in the screen shot which I did not put in but the OP seems to be happy with it. This answer is only on the circle with some noise added on the radius.
