This paper is based on general observation arising from many years experience in managing and delivering radiography services in the health service. In addition, it presents the results of a pilot qualitative study based on unstructured interviews. The interviews were undertaken with a view to identifying the reasons for radiography that may not be well justified. The study was undertaken in the public and private sectors and many of the reasons are shared by both. The reasons for poor justification include: inadequate radiation protection education for referrers; avoidance of medical litigation; defensive medicine attitude by referrers and, in the private sector, pursuit of profit. The study provides a starting point for further more quantitative investigations that are clearly required in the area.
