Occupational and patient exposure in interventional cardiology in Bosnia and Herzegovina.

Monitoring of professionally exposed workers in Bosnia and Herzegovina started in 1960s. Doses received by patients and professionals in interventional cardiology are high in comparison with other practices in medicine. The purpose of this study is to present personal and patient dosimetry data. Results show increase in doses of personnel in interventional cardiology. Total collective dose for four cardiology centres in Bosnia and Herzegovina increased from 15 person mSv in 2007 to 52 person mSv in 2010. This increase mainly corresponds to higher number of personnel and increase in the number of procedures. Average monthly dose has increased from 0.40 to 0.72 mSv in the same period. The results of occupational and patient doses in interventional cardiology are similar to results reported in the literature. It is of great importance for professionals working in this field to be educated in radiation protection and proper use of X-ray equipment.

Ten years of monitoring the occupational radiation exposure in Bosnia and Herzegovina.

Monitoring of occupationally exposed persons in Bosnia and Herzegovina started in 1960s and it was interrupted in 1992. Dosimetry service resumed in 1999 when the International Atomic Energy Agency provided Harshaw 4500 TLD-reader and the first set of TLDs for the Radiation Protection Centre (RPC) of the Institute of Public Health of the Federation of Bosnia and Herzegovina. In January 2009, the RPC covered 1279 professionals with personal dosimetry, which is more than 70 % of all radiation workers in the country. Most of the TLD users work in medical institutions. In period 1999-2003 RPC provided 984 workers with dosemeters. In the next 5 y period (2004-2008), the number of persons covered by dosimetry increased by an average of 51 %. The mean and collective effective dose in the period 1999-2003 were 1.55 mSv and 1.54 personSv, respectively. In the period 2004-2008, the mean doses changed by 1 % on average, but the collective effective dose increased by 53 % for all practices. Mean and collective effective dose were 1.57 mSv and 2.34 personSv, respectively. The highest personal doses are associated with industrial radiography, than exposures in nuclear medicine. Radiology plays a significant role in collective dose only, whereas other exposures are low. Results correspond to results found in the literature. New practices in industry and medicine emphasise the need for more personal dosemeters, as well as specialised dosemeters for extremities monitoring, etc.
