Comments on amendments and additions to the mandatory requirements for radiation safety in X-ray diagnostics and therapy

Starting from September 1, 2025, SanPiN 2.6.4115-25 came into force. This is a comprehensive document that establishes requirements for ensuring radiation safety when working with a specific list of ionizing radiation sources, including those used in X-ray diagnostics and therapy. As a result, several regulatory legal acts in the field of radiation safety will be repealed, including SanPiN 2.6.1.1192-03 and SanPiN 2.6.1.2891-11. SanPiN 2.6.4115-25 introduces a number of new as well as revised and updated requirements for ensuring radiation safety in the operation of ionizing radiation-generating equipment used in medical practice. This paper presents analysis of the changes and additions introduced in SanPiN 2.6.4115-25 in comparison with the documents that should be repealed starting from September 1, 2025, which previously regulated radiation safety requirements for X-ray diagnostics and therapy. Conclusion: The work presents the background for revising the sanitary rules and standards and provides recommendations for improving the regulation of radiation protection in medical exposure.
