The commission is authorised to propose approval, rejection, revocation or suspension of approval to ASN. It issues a decision on the basis of an application file submitted by the candidate laboratory and its results in the inter-laboratory comparison tests organised by IRSN. It meets every six months. The commission, chaired by ASN, comprises qualified persons and representatives of the State services, laboratories, standardising authorities and IRSN. ג ِ ב ِ ב ȵȵȸȒɮƏǼ ƬȒȇƳǣɎǣȒȇɀ Laboratories seeking approval must set up an organisation ŀĸĸŇļŁĺ ŇĻĸ ŅĸńňļŅĸŀĸŁŇņ łĹ ņŇĴŁķĴŅķ Ѽ ׇӄӊӃӅӈ concerning the general requirements for the competence of calibration and test laboratories. In order to demonstrate their technical competence, they must take part in ILTs organised by IRSN. The ILT programme, which now operates on a five-yearly basis, is updated annually. It is reviewed by the approval commission and published on the national network’s website ( mesure-radioactivite.fr ).

When the result obtained in an ILT by a laboratory is not conclusive enough, ASN 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.

Their direct and indirect effects on health and the environment are evaluated by the licensee in the facility’s impact assessment. Discharges into the natural environment and their effects must be as low as possible through the licensee’s use of the best available technologies. The discharge limit values for each facility are set by ASN resolutions.
