Use Window.Location or Window.Open

JavaScript

<script language="javascript">
<!--
function RadioCheck() {
 
var selection = document.quiz.radio;
for (i=0; i<selection.length; i++)
  if (selection[i].checked == true)
  window.location = "http://www.google.com/";
}
//-->
</script>

Because you're using a submit button, you need to return false to prevent the form submitting:

XML

<script language="javascript">
<!--
function RadioCheck() {
var selection = document.quiz.radio, urls = [
  'http://www.google.com/', 'http://www.bing.com/', 'http://yahoo.com/'
];
for (i=0; i<selection.length; i++)
  if (selection[i].checked)
    window.location = urls[i];
  return false; // ADD THIS!
}
//-->
</script>

You need a return in the onclick too:

<input type="submit" value="Check Answer" onClick="return RadioCheck()">
