Abstract		Background. The effects of the dispersed radiation described theoretically imply complex picture of interaction of the photon beam with the patient's body, as well as its dispersion on other structures. Basic theoretical laws of this phenomenon are highlighted, thus giving the opportunity to model the effect in total. Material and methods. The measurements of the absorbed dose in the air give isodose curves that show distribution of the radiation dose. For the urological procedures standard urological diagnostic methods were being used. Results. Through a large series of measuring, we got the distribution of the radiation dose in space, where urology diagnostics is being made using the X ray. The parameters determining this picture are the most frequent ones in the total number of 20 random cases taken in General Hospital in Doboj, Bosnia and Herzegovina. Conclusions. Static dosimetric picture of the space (radiation zone) in the general sense is useful before all for organisation of the diagnostic procedures utilising ionised radiation. Obtained in any way, this picture enables an insight into the three-dimensional distribution of the dosage on the basis of which it is possible to correct the organisation of the diagnostics being performed under these conditions. The values of the radiation dosage show it is necessary to use the protecting means prescribed by law. For more frequent exposure, it would be useful to make a dynamic dosimetric picture for professional exposure and assessment of the radiation risk of these persons.
Summary		Izhodišča. Učinki disperznega sevanja ustvarjajo kompleksno podobo delovanje fotonskega snopa na bolnikovo telo in disperzijo snopa na druge strukture. V raziskavi predstavljamo bistvene teoretične zakonitosti tega pojava. Material in metode. Z merjenjem doze v zraku smo dobili izodozne krivulje, iz katerih smo lahko ugotavljali porazdelitev absorbirane doze. Dozo smo merili med standardnimi urološkimi diagnostičnimi postopki. Rezultati. Med izvajanjem urološke diagnostike z žarki X smo z večkratnimi meritvami ugotovljali porazdelitev doze v prostoru. Parametri, ki so značilni za to sliko, so bili najbolj pogosti tudi v 20 naključno izbranih primerih v Splošni bolni*nici Doboj, v BiH. Zaključki. Statično dozimetrično prostorsko slikanje (sevalno območje) je na splošno zelo koristno predvsem v pripravah diagnostičnih postopkov z ionizirajočim sevanjem. Takšne slike omogočajo vpogled v tridimenzionalno porazdeljenost doze, na osnovi katere lahko spremenimo organiziranost diagnostičnega postopka, ki ga izvajamo v takšnih razmerah. Vrednosti obsevalne doze potrjujejo, da je nujno treba uporabljati zaščitna sredstva, predpisana z zakonom. Ob pogostejšem izpostavljanju sevanju je potrebna dinamična dozimetrična slika, ki se uporablja za ugotavljanje poklicne izpostavljenosti in oceno tveganja zaradi obsevanja pri izpostavljenih osebah.
