indicators for conducting regional and national assessments. This procedure is supplemented by more detailed investigations addressing specific themes defined in an annual or multi-year framework. The radiation protection situation in the medical environment has been assessed essentially on the basis of the indicators associated with the control points. 1.2.7 Oversight actions conducted in the context of the health crisis The health crisis associated with the Covid‑19 pandemic and the lockdowns have led ASN to adapt its oversight actions as described in chapter 3. In the medical sector, particularly affected by the workloads involved in the care and treatment of Covid‑19 patients, ASN suspended all inspections save exceptions during the first lockdown. Specific inspection methods were subsequently defined. Prior to any inspection, whether conducted on site or remotely, the person/entity in charge of the nuclear activity was contacted to verify that the healthcare centres had the staff necessary for the inspection to be carried out. 1.3  Regulations 1.3.1 General regulations Protection of the personnel working in facilities that use ionising radiation for medical purposes is governed by the provisions of the Labour Code (Articles R. 4451‑1 to R. 4451‑135 of the Labour Code). In order to protect the public and the workers, the facilities that use medical devices emitting ionising radiation must also satisfy the technical rules defined in the ASN resolutions (see points 4 to 7).
