What it regulates
It replaces the 1999 installation and 2006 high-activity source regulations. Alongside protection of installation personnel, it regulates outside undertakings, naturally occurring radioactive materials, workplace radon and aircrew. This page selects those duties and connects them with Royal Decree 1029/2022.
Who it applies to
Occupational selection from Articles 12, 13, 55, 80–81, 97–99, 101 and 103–106, plus final provision 2 and relevant transitions. This is not an inventory of all authorisations, waste, transport or nuclear-safety requirements. Environmental or financial parts of mixed provisions are excluded except for essential context.
Key provisions
Article 12 retains the holder’s responsibility and requires adequate resources and fit personnel. Substance testing must respect proportionality, prior information, dignity, privacy and confidentiality. Article 13 requires channels for reporting deficiencies and protection against retaliation under Law 2/2023.
Article 12The holder must define competencies and training programmes for personnel whose work directly or indirectly concerns nuclear safety or radiation protection. Everyone working in the installation must know radiation and emergency rules. Article 80 governs stopping operation when safety deteriorates and fitness of licensed personnel.
Article 81For high-activity sealed sources, Article 55 requires leak-tightness testing at least annually and after relevant incidents, monthly presence and condition checks, and specific training. It distinguishes a maximum one-hour notification for loss, theft, leakage or unauthorised use from a maximum twenty-four-hour notification for incidents involving possible unintended exposure.
Article 55Outside undertakings covered by Article 55 of Royal Decree 1029/2022 must declare their activities for the CSN register and report changes. Final provision 2 expressly updates that reference in the 2022 health regulation; registration does not replace substantive prevention duties.
Article 97Activities involving naturally occurring radioactive materials must assess their risk through an authorised service or technical unit. If not exempt, they must implement the Article 99 programme; the document is sent to the CSN within one month of issue and the annual report is prepared in the first quarter. Article 101 governs the radiation-protection technician where required by the CSN.
Article 98Article 103 requires action where workers can access areas with annual average radon above 300 Bq/m³. If no area where workers stay exceeds 1,000 Bq/m³, the general declaration deadline is one year from the report, subject to the stated extensions and exemptions; if any does, it is one month. Workers must be informed and the required specialist advice and corrective measures followed.
Article 103If, despite corrective measures, a worker may receive more than 6 mSv annually from radon, Article 104 requires a dose-monitoring programme and information to the CSN. Possible exposure above 20 mSv annually requires immediate action, including relocation if necessary. These are action thresholds, not permission to expose workers.
Article 104Airlines must implement an aircrew radiation-protection programme with monthly dose calculations, individual records according to the legal thresholds, specific training and health surveillance. Article 106 requires informing personnel and sending estimated doses to the CSN in the first half of each year.
Article 106History and versions
BOE publication: 04/12/2024 · Initial entry into force: 05/12/2024

Original text, repeals and targeted amendment of the 2022 health regulation.
BOE-A-2024-25205IS-49, published on 8 October 2026 and effective the next day, provides technical decommissioning rules. Its transitional clause excludes authorisations granted before publication. This is implementing context, not new wording of the selected OSH provisions.

Transitional provisions and application notes
General commencement was 5 December 2024. Final provision 7(2) deferred specific Article 98(1)(b) requirements for existing activities and Articles 99 and 101 for twelve months; that period had elapsed by this page’s review date. It did not defer the entire regulation.
Final provision seventhTransitional provisions 1–3 preserve authorisations and certain licences or diplomas. Existing operator and supervisor licences for installations outside the fuel cycle are extended until ten years from their issue or last renewal, not for a new ten-year period starting in 2024.
Transitional provision secondTransitional provision 6 distinguishes adaptation deadlines by authorisation and activity; provision 9 retains earlier rules for pending proceedings, with its specific exception. A single adaptation deadline cannot be assigned to all installations and activities.
Transitional provision sixthRoyal Decree 1029/2022 remains the health-protection regulation, as amended: Royal Decree 1217/2024 changes its Articles 55(a) and 82(1) and repeals additional provisions 7–9. The new installation rules do not replace the whole radiation-health regime.
