Sažetak
Radium sources were used in Croatia for various applications in medicine and industry for many years. Due to their undesirable characteristics, almost all of these sources have been replaced by more modern sources. Storage of these unused sources, especially in developing countries, is often inadequate. Conditioning of radium sources for proper storage is one of major objective of the Waste Technology Section of IAEA.
The conditioning of the spent radium sources in Croatia was performed by a specially trained team from the Austrial Research Center Seibersdorf, under contract to the IAEA, using an IAEA developed and approved procedure. The source conditioning took place in a waste storage and treatment facility at the Ruđer Bošković Institute, Zagreb, Croatia.
The conditioning of the national radium stock in Croatia was performed within the period from 13-17 October 1997. The total inventory was 1316 mg (298 sources, 49 GBq). The sources were mainly needles and tubes. All spent radium sources were conditioned in 25 small capsules and one large capsule. The capsules were put into three shilding devices and two packages (drums) were produced. The total activity/shield is still under the transportation regulation limit. Experimental procedure was described and discussed.
No complications in this operation were experienced. The operation caused no contamination and hence no decontamination was required.
