Radiation protection — Apparatus for industrial gamma radiography — Specifications for performance, design and tests
ISO 3999:2004 specifies the performance, design and test requirements of apparatus for gamma radiography with portable, mobile and fixed exposure containers of the various categories defined in Clause 4. It applies to apparatus designed to allow the controlled use of gamma radiation emitted by a sealed radioactive source for industrial radiography purposes, in order that persons will be safeguarded when the apparatus is used in conformity with the regulations in force regarding radiation protection. It is emphasised, however, that so far as transport of apparatus and sealed radioactive source is concerned, compliance with ISO 3999:2004 is no substitute for satisfying the requirements of relevant international transport regulations (IAEA Regulations for the safe transport of radioactive materials: IAEA-STI-PUB 998, Safety Standards Series ST-1 and ST-2, and/or the relevant national transport regulations). The operational use of apparatus for industrial gamma radiography is not covered by ISO 3999:2004. Users of this equipment shall comply with national regulations and codes of practice.
Radioprotection — Appareils pour radiographie gamma industrielle — Spécifications de performance, de conception et d'essais
L'ISO 3999:2004 spécifie les exigences en matière de performance, de conception et d'essais d'un appareillage pour radiographie gamma, comportant des projecteurs portatifs, mobiles ou fixes appartenant aux diverses catégories définies à l'Article 4. L'ISO 3999:2004 s'applique à un appareillage conçu pour permettre l'utilisation contrôlée du rayonnement gamma émis par une source radioactive scellée à des fins de radiographie industrielle, de façon que le personnel soit en sécurité, quand cette utilisation est faite en conformité avec la réglementation en vigueur en matière de radioprotection. On souligne cependant, que pour ce qui concerne le transport de l'appareil et de la source radioactive scellée, la conformité aux exigences de la présente Norme internationale ne se substitue pas, pour autant, à la conformité aux exigences des règlements internationaux des transports applicables (Règlement de l'AIEA pour la sûreté des transports des matières radioactives: IAEA-STI-PUB 998, Safety Standards Series ST1 et ST2, et/ou règlements de transport nationaux applicables). L'utilisation pratique d'un appareillage pour radiographie gamma industrielle n'est pas couverte par la présente Norme internationale. Les utilisateurs de cet équipement doivent se conformer aux règlements et codes de pratique nationaux.
Radiološka zaščita - Naprave za industrijsko gama radiografijo - Specifikacije za delovanje, načrtovanje in preskuse
Ta mednarodni standard določa zahteve za delovanje, načrtovanje in preskuse naprav za gama radiografijo s prenosnimi, mobilnimi ter fiksnimi vsebniki za izpostavljanje različnih kategorij, opredeljenih v točki 4.
Uporablja se za naprave, ki omogočajo nadzorovano uporabo sevanja gama iz zaprtega radioaktivnega vira za namene industrijske radiografije, da so osebe zaščitene, kadar se naprava uporablja v skladu z veljavnimi predpisi glede radiološke zaščite.
Ob tem je treba poudariti, da skladnost s tem mednarodnim standardom v zvezi s prevozom naprave in zaprtega radioaktivnega vira ne nadomešča izpolnjevanja zahtev ustreznih mednarodnih prevoznih predpisov (predpisov Mednarodne agencije za atomsko energijo (IAEA) za varen prevoz radioaktivnih snovi:
IAEA-STI-PUB 998, varnostni standardi serij št. ST-1 in št. ST-2 in/ali ustreznih nacionalnih prevoznih predpisov).
Ta mednarodni standard ne zajema operativne uporabe naprav za industrijsko gama radiografijo. Uporabniki te opreme morajo upoštevati nacionalne predpise in kodekse ravnanja.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3999 was prepared by Technical Committee ISO/TC 85, Nuclear energy, Subcommittee SC 2, Radiation
protection.
This second edition cancels and replaces ISO 3999-1:2000, of which it constitutes a minor revision.

tests
1 Scope
This International Standard specifies the performance, design and test requirements of apparatus for gamma
radiography with portable, mobile and fixed exposure containers of the various categories defined in Clause 4.
It applies to apparatus designed to allow the controlled use of gamma radiation emitted by a sealed
radioactive source for industrial radiography purposes, in order that persons will be safeguarded when the
apparatus is used in conformity with the regulations in force regarding radiation protection.
It is emphasised, however, that so far as transport of apparatus and sealed radioactive source is concerned,
compliance with this International Standard is no substitute for satisfying the requirements of relevant
international transport regulations (IAEA Regulations for the safe transport of radioactive materials:
IAEA-STI-PUB 998, Safety Standards Series No. ST-1 and No. ST-2, and/or the relevant national transport
regulations).
The operational use of apparatus for industrial gamma radiography is not covered by this International
Standard. Users of this equipment shall comply with national regulations and codes of practice.
