Try this - 

if ($('#emp_form :radio').length != 0) {
    alert('exists');
  } else {
    alert('does not exist');
  }

You can use .find() (or just a descendant selector) and check the .length like this:

if($("#emp_form :radio").length == 0) {
  alert("No radio buttons found!, Crap!");
}

Of if you want to do something in the case there are radio buttons:

if($("#emp_form :radio").length > 0) {
  //do something
} else {
  alert("No radio buttons found!, Crap!");
}

The .find() alternative is $("#emp_form").find(":radio").length.
