Control of radioactive sources


The Spanish Nuclear Safety Council (CSN) controls and periodically inspects (normally annually) radioactive sources in accordance with the Regulation on nuclear and radioactive facilities.

There are also specific regulations for the control of high-activity radioactive sources and orphan sources that set obligations for the CSN regarding their control, this organisation being responsible for creating and maintaining a national inventory of high-activity radioactive sources and their owners as well as setting up a system for monitoring and controlling the transfers of these sources from their entry into the country until its exit, at the end of their useful life, or their storage as radioactive waste in an authorised facility.

To manage these inventories and monitor their transfers, a standard inventory sheet must be sent to the CSN whenever a new source enters or its location changes. The regulations also include requirements for the periodic checking of the location and condition of these sources to prevent and avoid any loss, theft or unauthorised transfer of them.
