Diagnostični referenčni nivoji (DRN-ji) so eno od orodij, ki je v pomoč pri zaščiti pacientov, izpostavljenim ionizirajočemu sevanju v medicini. So vrednosti, na podlagi katerih se da obsevanost pacientov v različnih ustanovah in državah primerjati med sabo. V zaključni nalogi je opisan pomen vzpostavitve DRN-jev in njihova vloga v zakonodaji. Opisana je metoda določanja vrednosti DRN in dozimetrične količine, ki so s tem povezane. Predstavljen je projekt, v katerem so določili vrednosti DRN za večino evropskih držav. Vrednosti DRN v Sloveniji smo določili za 36 preiskav na področju konvencionalne radiografije in 16 preiskav iz področja računalniške tomografije. Uporabili smo podatke iz podatkovne baze Orqa, ki je v lasti ZVD. Posebno smo se osredotočili na določitev na določitev negotovosti izračunanim vrednostim DRN, določili smo jih po dveh različnih metodah in jih med sabo primerjali. Na koncu smo naše rezultate primerjali z znanimi evropskimi DRN-ji.

• Title: Determining the diagnostic reference levels in conventional radiological procedures and computed tomography in Slovenia

Abstract

Diagnostic reference levels (DRLs) are one of the practical tools designed to help protect patients exposed to ionizing radiation in medical imaging. They are quantitative values which allow comparison of radiation of patients in different institutions and countries can be compared with one another. This thesis outlines the importance of collecting the DRLs and their legal status. The method used for determining the DRLs' value and the associated dosimetric quantities is described. The DRLs in Slovenia were based on 36 examinations in the field of conventional radiography and 16 examinations in the field of computed tomography. We used data from the Orqa database, which is managed by the Institute of Occupational Safety (ZVD). In addition the focus was on determining the uncertainty of the calculated DRLs’ values, which was done by using two different methods and then comparing them with each other. Finally, we compared the results with DRL values obtained in some EU countries.
