How Make 4 check boxes behave like radio button for eService Application

We want to introduce 2 new screens for the forgot password functionality for external application, where we want the user to set the security questions after selecting the one address out of 4 address options he lived in one screen & one employer from 4 employer options in another screen he worked for.

1. Screen with 4 Checkbox to select one address, once selected one checkbox other should be unchecked
2. Screen with 4 Checkbox to select one employer, once selected one checkbox other should be unchecked

Tried the using OnFieldUpdateSet BC user property to make the flags "N" when one is "Y"

Any Script or any configuration solution or any browser level scripting to capture the "checked" property to set it to null, for this is appreciated.
