[en] The data collected during the investigations could be important as a useful baseline for future patient dose measurements in the field of the medical diagnostic radiology. Evaluation of patients doses is an important part of quality assurance programme in diagnostic radiology. It seems that the most convenient way to measure patient doses is by using K.A.P.-meter. The procedure could be performed by educated radiographers, it is simple and it does not require a lot of additional measurements. It can be combined with average values of field-size and focus-skin distance, and that would make calculations even easier. If Q.C. data is used to calculate entrance surface dose (E.S.D.) than radiographers would have to write down all the parameters that have been used during the examinations. In most of the cases that is an every day practice, and therefore is very inconvenient. The thermoluminescent dosemeter (T.L.D.) method is good but requires more time and effort. Besides that, Bosnia and Herzegovina does not have facilities to read patients T.L.D.s. The optimal solution for future assessment of national diagnostic reference levels (D.R.L.) is the combination of these three methods. Bigger radiological departments that employ a physicist should have Q.C. equipment (various dosemeters, K.A.P. meter ). In this case values from several methods could be obtained. Regional hospitals that do not employ physicists could have K.A.P. meters that would be operated by educated radiographers. Values in other smaller radiological departments can be derived from the patients records and exposure conditions. Radiation protection centres in the country should be equipped with appropriate T.L.D. readers. in that case some of data could be collected using this method. (N.C.)
