I would suggest one of two things:
(1) If the user is to be able to check multiple RadioButtons then use
CheckBoxes instead as the user might be confused since this goes against the
"normal" usage of this control.
(2) If you really must do this, place any RadioButtons that can be checked
at the same time in different Panels.
