The Government’s Code of Conduct covering body scanners states: ‘An individual may opt out of being scanned. In this instance, the individual must either be screened by an alternative method which includes at least an enhanced hand search in private or that individual must not be permitted to enter the security restricted area, or, if applicable, he or she must be removed from it. An enhanced hand search in private must take place in a private room or an area away from the main search comb. This may involve the loosening or removal of clothing.
