UK Borders Bill

My Lords, I must voice some disquiet at the use of ionising radiation in any form when it is for the purposes of a non-medical intervention. It raises concerns. Irrespective of the EU directive, is the Minister completely satisfied that that kind of intervention is ethically justified given that the information that one would get from such an X-ray would be of only limited value and that assessment of a young person can be made by other means that are sufficiently adequate in most cases?
