LES ACTIVITÉS NUCLÉAIRES : RAYONNEMENTS IONISANTS ET RISQUES POUR LA SANTÉ ET L’ENVIRONNEMENT Approvals cover all environmental matrices for which licensees are required to carry out regulatory monitoring: water, soil or sediment, biological matrices (fauna, flora, milk), aerosols and atmospheric gases. The measurements concern the main artificial or natural gamma, beta or alpha emitting radionuclides, as well as the ambient gamma dosimetry. The list of the types of measurements covered by an approval is set by the above-mentioned amended ASN resolution 2008-DC-0099 of 29 April 2008. In total, the approvals cover about fifty measurements, for which there are as many proficiency tests (formerly known as a Interlaboratory Comparison Tests (ILTs). These tests are organised by ASNR in a five-year cycle, which corresponds to the maximum approval validity period. In 2025, ASNR issued 285 approvals or approval renewals. As at 31 December 2025, the total number of approved laboratories stood at 68, which represents 988 approvals of all types currently valid on 1 January 2026. The detailed list of approved laboratories and their scope of technical competence is available on asnr.fr. 5.3.2 – Laboratory approval procedure The above-mentioned amended ASN resolution 2008-DC-0099 of 29 April 2008 specifies the organisation of the national network and sets the approval arrangements for the environmental radioactivity measurement laboratories. The approval procedure notably includes: ∙presentation of an application file by the laboratory concerned, after participation in an Inter-laboratory Comparison Test (ILT); ∙review of it by ASNR; ∙examination of the application files – which are made anonymous – by a pluralistic approval commission which delivers an opinion on them. The laboratories are approved by ASNR resolution published in its Official Bulletin. The list of approved laboratories is updated every six months and published on asnr.fr. The approval commission is tasked with ensuring that the measurement laboratories have the organisational and technical competence to provide the RNM with high-quality measurement results. The commission is authorised to propose approval, rejection, revocation or suspension of approval to ASNR. It issues a decision on the basis of an application file submitted by the candidate laboratory and its results in the ILTs organised by ASNR. It meets every six months. The commission, chaired by ASNR, comprises qualified persons and representatives of the State services, laboratories, standardising authorities and ASNR experts. In 2023, ASN renewed the composition of the approval commission in ASN Chairman’s resolution CODEP-DEU-2023-052098 of 13 October 2023, concerning nominations to the approvals commission for environmental radioactivity measurement laboratories. 5.3.3 – Approval conditions and competence tests Laboratories seeking approval must set up an organisation meeting the requirements of standard NF EN ISO/IEC 17025 concerning the general requirements for the competence of calibration and test laboratories. In order to demonstrate their technical competence, they must take part in Inter-laboratory Comparison Tests (ILTs) organised by ASNR. The five-year programme for these tests is updated annually. It is reviewed by the approval commission and published on the RNM’s website. Up to 70 laboratories sign up for a type of test, including a number of laboratories from other countries. The approval commission defines the evaluation criteria used for analysis of the ILTs. When the result obtained in an ILT by a laboratory is not conclusive enough, ASNR may, on the advice of the approval commission, issue an approval for a trial period of one to two years for example, or make issue of the approval dependent on the provision of additional data, or even the participation in a further corroborating test. In 2025, ASNR organised six ILTs and two corroborating tests. Since 2003, 121 ILTs have been carried out, covering 60 types of approval. The largest number of approved laboratories is for monitoring of radioactivity in water, with 53 laboratories. Between 30 and 44 laboratories are approved for measurement of biological matrices (fauna, flora, milk), atmospheric dust, air, or ambient gamma dosimetry. For soil and sediment, the number of approved laboratories is 28. Although most laboratories are competent to measure gamma emitters in all environmental matrices, between 10 and 20 of them are approved to measure carbon-14, transuranic elements or radionuclides of the natural chains of uranium and thorium in water, soil and sediments and the biological matrices (grass, plant crops or livestock, milk, aquatic fauna and flora, etc.). 6 – Inspection of suppliers and manufacturers 6.1 Inspection scopes The quality of the manufacture of safety-important equipment for nuclear facilities is an essential factor in the safety of facilities and transport. ASNR: ∙evaluates the design and manufacturing of Nuclear Pressure Equipment. These controls are detailed in chapter 8, point 2.2.2; ∙controls the manufacture of packaging for the transport of radioactive substances. These controls are detailed in chapter 7, point 4.2.1; ∙inspects the supply chain for safety-critical materials intended for nuclear installations (see chapter 8, Highlight No. 16); ∙controls the manufacturers and distributors of radioactive sources. These controls are detailed in chapter 6, point 4. ASNR’s objective remains to ensure the quality of production, particularly in the context of the construction of new nuclear facilities. The industry as a whole must demonstrate a high level of rigour, and licensees must exercise their responsibility to achieve the expected quality. 6.2 Organisation of controls With regard to suppliers of equipment for nuclear installations, ASNR is implementing a strategy within licensees’ central departments to control: ∙purchasing processes, ∙production management, ∙monitoring of the subcontracting chain, ∙consideration of the risks of “Counterfeit, Falsification or Suspected Fraud” (CFS).
