The RadioButton UI element is a switch with two states (on/off) that enables users to select options. The RadioButton UI element allows you to arrange the RadioButtons individually on the screen instead of grouping them in a table.You can toggle RadioButtons if you bind the UI elements to the same context attribute.
The RadioButton is selected if the context attribute, to which the selectedKey property is bound, contains the value of the key belonging to this radio button. The key is specified by the keyToSelect property.

Accessibility
To enable the development of accessible applications, the tooltip property is checked during the syntax check if the text label properties are not set.
A tooltip does not necessarily have to be set for this UI element, but it could make sense to set it if it contains detailed semantic information.
