Sažetak
New Croatian radiation protection law regulations are based, among other positive principles, on the principle of establishing the controlled area in which the workers undergo legal and obligatory external occupational dosimetry monitoring. Outside the area the 1 mSv/year level of exposure is not to be exceeded by the operating radiation source. &#8220 ; Ort&#8221 ; is the common name for the above mentioned &#8220 ; outside area&#8221 ; which is to be monitored. The new digital dosimeter device ALARA OD, produced by ALARA Instruments Ltd. has the probe sensitive to the background radiation and fast enough to record any change in normal environmental-background radiation field. If user or dosimeter device enter the higher radiation field area or radiation source produces higher radiation output, second mode will separately start to measure the dose which is at least two times higher than the background at the spot. This methodology of measurement was performed one year long with the set of 60 devices on more than 35 X-ray units used for the civil baggage control on the airports and else. The dosimeter device was a part of whole xray system, meaning that one device was always on the spot which was recommended from the manufacturer as a spot with highest external exposure possibilities if any at all. Devices integrated the radiation for the whole year (battery cap. 5 years) and the net result is that there is no need for obligatory dosimetry monitoring of the workers and other stuff working with or near such X-ray units because the integrated dose while X-ray units working on the full load did not exceed the 1 mSv/year level.
