Sažetak
Based on Law on radiological and nuclear safety (NN 28/10), new Code of approvals and licenses for usage and transportation of ionizing radiation sources (NN 71/12) were recently endorsed. It stipulates that each institution operating source of ionization must establish a radiation safety risk assessment procedure. Risk analysis in institutions that operate ionizing radiation sources, like accelerators, X-ray devices and gamma ray sources, where energy levels diverse from 100kV to 10MeV, requires consistency in detailed control and anticipation of all potential hazards for staff and
environmental protection. FMEA (Failure Mode Effects Analysis) analysis risk assessment parameters include functional elements of X-ray operational system. Each is evaluated for potential risks and rated by factors, that combined offer RPN (Risk Priority Number) factor
showing exact level of risk for each functional element of working places and processes. RPN finally defines precisely areas of high, and low risks as defined by Code NN 71/12. Because of not so clear definition of high risk and areas of high surveillance need it could
results in different approaches. FMEA offers clear and well defined results of risk operation zones and necessary processes under control.
