title: Lead thickness in shielding in the protection of radiodiagnostic staff.
abstract: We indicate the principles which can be used to apply cost-benefit analysis to radiation protection of staff in an X-ray department. The cost of saving radiation exposure to staff by varying the lead equivalence of lead gowns and lead protective screens is calculated. The cost is compared with the financial values of the detriment as assessed by the National Radiological Protection Board. The expenditure required to avoid a man-Sv for staff protection in diagnostic departments is suggested. In the examples we take, it is found that the larger staff dose reductions, and often the cheaper reductions, can be obtained by reducing the radiation dose to the patient. There are, of course, major additional advantages to the patient in reducing this dose.
