html is

 set 1</br>

<input type="radio" name="set1" value="1" />
<input type="radio" name="set1" value="2" />
<input type="radio" name="set1" value="3" />
<input type="radio" name="set1" value="4" />

<br/>
set2</br>
<input type="radio" name="set2" value="1" />
<input type="radio" name="set2" value="2" />
<input type="radio" name="set2" value="3" />
<input type="radio" name="set2" value="4" />

and javascript is

$('input[name=set1]').click(function() {
    $('input[name=set2]').prop({disabled:false});
    $('input[name=set2][value='+$(this).val()+']').prop({disabled:true});
});

$('input[name=set2]').click(function() {
    $('input[name=set1]').prop({disabled:false});
    $('input[name=set1][value='+$(this).val()+']').prop({disabled:true});
});

Try this:

$(document).ready(function () {
      var EValue;
      var MValue;
      EValue = $("input:radio[name='E_message']:checked").val();
                   //COuld be something like
      Mvalue = $("input:radio[name='M_message']").val();//syntax error here
     if(EValue == MValue)
      {
         $("input:radio[name='M_message']").attr("disabled", "disabled");//also use single quotes

      }
 });
