For countries: Only Member States of the IAEA may join INIS. A formal letter should be sent from either the national atomic energy authority, or from the country's Permanent Mission to the IAEA, or from the Ministry of Foreign Affairs. The letter should be addressed to the Director General of the IAEA and should state the country's wish to join INIS. The letter should include the commitment to fulfill the responsibilities of an INIS Member and the nomination of the national INIS Liaison Officer, with whom the INIS Secretariat would work closely on all INIS-related matters. An Alternate Liaison Officer may also be nominated.
For international organizations: A formal letter should be sent from the Executive Head of the organization, addressed to the Director General of the IAEA, stating the organization's wish to join INIS and undertaking to fulfill the responsibilities of an INIS Member and, nominating an INIS Liaison Officer, with whom the INIS Secretariat would work closely on all INIS-related matters. An Alternate Liaison Officer may also be nominated.
The INIS Liaison Officer is responsible for organizing the collection of information and the preparation of input for INIS on a national level (or for his organization, in the case of an international organization), as well as for the dissemination of information contained in all INIS output products, in addition to the promotion of those products. Regular communication between the INIS & NKM Section and the INIS Liaison Officers takes place by correspondence and through the annual Consultative Meetings of INIS Liaison Officers.
The purpose of the Alternate INIS Liaison Officer is to have another person from each INIS Member officially designated to act as Liaison Officer in the absence of the designated Liaison Officer.
