A single radio button performs the same basic function as a Gtk2::CheckButton, as its position in the object hierarchy reflects. It is only when multiple radio buttons are grouped together that they become a different user interface component in their own right.
Every radio button is a member of some group of radio buttons. When one is selected, all other radio buttons in the same group are deselected. A Gtk2::RadioButton is one way of giving the user a choice from many options; Gtk2::OptionMenu and Gtk2::ComboBox (added in gtk+ 2.4) are alternatives.
Each constructor can take either a group or widget from that group where the group is wanted; this is an enhancement over the C API. Nevertheless, the _from_widget forms are provided for completeness.

$member_or_listref (scalar) reference to radiobutton group or a Gtk2::RadioButton belonging to that group.
$label (string)
Create a radio button. If $label is provided, it will be interpreted as a mnemonic. If $member_or_listref is undef, the radio button will be created in a new group.
$member_or_listref (scalar) reference to radiobutton group or a Gtk2::RadioButton belonging to that group.
$label (string)
Create a radio button with a plain text label, which will not be interpreted as a mnemonic.
$member_or_listref (scalar) reference to radiobutton group or a Gtk2::RadioButton belonging to that group.
$label (string)
Create a radio button with a mnemonic; this is an alias for new.
Return a reference to the radio group to which $radio_button belongs.
The group is a reference to an array of widget references; the array is not
magical, that is, it will not be updated automatically if the group changes;
call get_group each time you want to use the group.
Assign $radio_button to a new group.
