Radio-button label

... The label can be positioned before or after the radio-button by setting the labelPosition property to 'before' or 'after'.

Radio groups

Radio-buttons should typically be placed inside of an <mat-radio-group> unless the DOM structure would make that impossible ... The radio-group has a value property that reflects the currently selected radio-button inside of the group.
