What it regulates
It established controls for high-activity sealed sources, training and responses to losses and incidents to prevent unintended exposure. Orphan-source rules were separated in 2020 and the rest of the decree was repealed in 2024. Its deadlines and frequencies are presented as historical rules, not independent current duties.
Who it applies to
Historical selection: Article 1 insofar as it protects workers, Articles 8(a)–(d) and 8(g), 9(3), 10, 11(3) and 11(5), and the sole additional provision. Financial guarantees, commercial transfers and environmental rules without an occupational link are not covered.
Key provisions
Article 8(a) required leak-tightness and surface-contamination tests by an authorised body, at intervals of no more than one year and after incidents that might affect source integrity.
Article 8The holder had to check the source’s presence and apparent condition monthly and retain records. It had to document measures against unauthorised access, loss, theft and fire damage.
Article 8It distinguished immediate notification, within one hour at most, of loss, theft or unauthorised use from notification as soon as possible, within twenty-four hours at most, of incidents involving actual or possible unintended exposure. Reports had to reach the authorities listed in the article.
Article 8Article 10(1) required training every two years for all exposed workers in source-holding installations. It covered safe management, consequences of loss of control and response, and formed part of the operating rules and internal emergency plan.
Article 10Former Article 10(2) governed information and training where orphan sources were likely to be found. It was repealed in 2020 alongside Articles 11 and 12; training in that field moved to Article 14 of Royal Decree 451/2020.
