Resolution No.4 of 2026 regarding waste and refuse containing radioactive materials that are exempt from the requirement to obtain prior authorization for their disposal.

This Resolution, consisting of 3 articles and 3 tables, establishes the criteria for exempting radioactive waste and materials from regulatory control, including exemption levels for artificial and naturally occurring radionuclides, dose constraints, notification and dose assessment requirements, and calculation methods for mixtures of radionuclides to ensure compliance with the applicable exemption criteria. The three tables establish (1) exemption levels for moderate quantities of artificial radionuclides based on activity concentration and total activity; (2) activity concentration exemption levels for bulk solid materials containing artificial radionuclides; (3) activity concentration exemption levels for materials containing naturally occurring radionuclides, such as potassium and uranium.
