Both will do it below, as long as _radioContainer is a GroupBox.

private void button1_Click(object sender, EventArgs e) {

    // This will remove the radiobuttons completely...
    _radioContainer.Controls.OfType().ToList().ForEach(p => _radioContainer.Controls.Remove(p));

    // Either of the below will clear the checked state
    _radioContainer.Controls.OfType().ToList().ForEach(p => p.Checked = false);

    foreach (RadioButton radio in _radioContainer.Controls.OfType().ToList()) {
        if (radio.Checked == true) {
            radio.Checked = false;
            break;
        }
    }
}
