    What it regulates

    Approves radiation-protection regulations covering occupational exposure, area and worker classification, dosimetry, health surveillance and radon at work.

    Who it applies to

    The legislation also protects the public and the environment. This record is limited to occupational health and safety: activities involving occupational exposure to ionising radiation, outside workers and existing occupational exposure situations, including radon where specified.

    Key provisions

    The ordinary effective-dose limit for exposed workers is 20 mSv per calendar year; separate equivalent-dose limits apply to the lens, skin and extremities. Distinguish these from specially authorised and emergency exposures.

    Article 11

    Once pregnancy is reported, adapt working conditions so that the equivalent dose to the fetus does not exceed 1 mSv for the remainder of pregnancy; after breastfeeding is reported, avoid work with significant intake or contamination risk.

    Article 12

    Assess conditions in advance, classify and demarcate areas and classify workers, apply rules and controls, and arrange individual monitoring and health surveillance according to exposure.

    Article 17

    Estimate annual average radon in the specified underground workplaces, groundwater-related activities and ground or basement floors in priority municipalities. Above 300 Bq/m³, reduce concentration or exposure and reassess.

    Article 75

    Estimate exposure using long-term measurements and laboratories with valid accreditation, following CSN guidance and instructions; keep the report available to workers and authorities.

    Article 76

    Transitional provisions and application notes

    • It repealed Royal Decrees 783/2001 and 413/1997. Transitional preservation of certain coefficients or authorisations does not keep those decrees wholly in force.

      Repealing provision sole

    • Authorisations valid when the regulations took effect remain valid until expiry; subsequent renewals follow the new regulations.

      Transitional provision first

    • The new lens limits were deferred for eighteen months from 22 December 2022 and apply from 22 June 2024. For exposed workers, Article 11(2)(a) sets 100 mSv over five consecutive years and a maximum of 50 mSv in any one year.

      Transitional provision second

    • The third transitional provision refers to internal-dose coefficients in Annex III of Royal Decree 783/2001 until the CSN updates them. Check the applicable technical instruction before a specific calculation; this record does not assert that no later update exists.

      Transitional provision third

    • The one-year temporary regime for certain radon personal-dosimetry laboratories concerned the initial 2022–2023 period; it is not indefinite permission to operate without authorisation.

      Transitional provision fourth

    • Deferred application of the specified radon and construction-material requirements ended on 22 June 2024. Consult Instruction IS-47 of 2025 as well for priority municipalities and measurement methodology.

      Final provision fifth

    • Royal Decree 1217/2024 repealed the seventh to ninth additional provisions and amended Articles 55(a) and 82(1) from 5 December 2024. This is a partial repeal, not repeal of the whole of Royal Decree 1029/2022.

      Additional provision seventh

    • CSN Instruction IS-47, in force since 2 May 2025, identifies priority municipalities by reference to DB HS-6 Zone II and specifies methodology and updating of radon surveys. Check the classification applicable to the site.
