[en] The generation rate of disused radioactive sources of industrial origin that are managed as Radioactive waste in Chile amounts to more than 100 units per year, with annual average activity of 18 Terabequerelios on the date of receipt at the radioactive waste management facilities. The objective of this work is to present the activities developed for the implementation of the process of conditioning of radiation sources in recoverable form, of categories 3 and 4, according to International Atomic Energy Agency standards and national regulatory framework. Inventory of existing radioactive waste, sources of Cesium 137 and Cobalt 60 were selected. The dismantling and obtaining the radioactive source itself, by brand and model of equipment originals, allowing verification of their physical and radiological characteristics. The operation was carried out in a sufficient armor workbench for a total activity of 250 Gigabequerels. The conditioning was done by depositing the sources in stainless steel capsule limited by the volume and activity of each source. The safety barriers for the capsule consist of shielding of lead and mortar jacketed container. As a result of this operation, a total of 111 sources of Cesium 137 with 150 Gigabequerels and 46 units of Cobalt 60 with 12 Gigabequerels They were conditioned in this operation. The radiation doses in contact with the final package are 0.5 milliSievert / hour for the bulk of Cesium and 0.1 milliSievert / hour for the bulk of Cobalt, complying with the operating conditions of the conditioned waste warehouse.
