Guidance for gamma spectrometry measurement of radioactive waste (ISO 19017:2015)
ISO 19017:2015 is applicable to gamma radiation measurements on radioactive waste.
Radioactive waste can be found in different forms and exhibit a wide range of characteristics, including the following:
- raw or unconditioned waste, including process waste (filters, resins, control rods, scrap, etc.) and waste from dismantling or decommissioning;
- conditioned waste in various forms and matrices (bitumen, cement, hydraulic binder, etc.);
- very low level (VLLW), low level (LLW), intermediate level (ILW) and high level radioactive waste (HLW);
- different package shapes: cylinders, cubes, parallelepipeds, etc.
Guidance is provided in respect of implementation, calibration, and quality control. The diversity of applications and system realizations (ranging from research to industrial systems, from very low level to high level radioactive waste, from small to large volume packages with different shapes, with different performance requirements and allowable measuring time) renders it impossible to provide specific guidance for all instances; the objective of this International Standard is, therefore, to establish a set of guiding principles. Ultimately, implementation is to be performed by suitably qualified and experienced persons and based on a thorough understanding of the influencing factors, contributing variables and performance requirements of the specific measurement application.
This International Standard assumes that the need for the provision of such a system will have been adequately considered and that its application and performance requirements will have been adequately defined through the use of a structured requirements capture process, such as data quality objectives (DQO).
It is noted that, while outside the scope of this International Standard, many of the principles, measurement methods, and recommended practices discussed here are also equally applicable to gamma measurements of items other than radioactive waste (e.g. bulk food, water, free-standing piles of materials) or to measurements made on radioactive materials contained within non-traditional packages (e.g. in transport containers).
Leitfaden für gammaspektrometrische Messungen von radioaktivem Abfall (ISO 19017:2015)
Lignes directrices pour le mesurage de déchets radioactifs par spectrométrie gamma (ISO 19017:2015)
L'ISO 19017:2015 s'applique aux mesurages des rayonnements gamma dans les déchets radioactifs.
Les déchets radioactifs peuvent se présenter sous différentes formes et révéler des caractéristiques extrêmement diverses, notamment:
- les déchets bruts ou non conditionnés, y compris les déchets de procédé (filtres, résines, barres de contrôle, rebuts, etc.) et les déchets d'assainissement ou de démantèlement;
- les déchets conditionnés sous diverses formes et matrices (bitume, ciment, liant hydraulique, etc.);
- les déchets radioactifs de très faible activité (TFA), de faible activité (FA), de moyenne activité (MA) et, de haute activité (HA);
- les différentes formes de colis: cylindres, cubes, parallélépipèdes, etc.
Les préconisations données portent sur la mise en ?uvre, l'étalonnage et le contrôle qualité. La diversité des applications et des réalisations de systèmes (allant des activités de recherche aux systèmes industriels, des déchets radioactifs de très faible activité aux déchets de haute activité, des colis de faible volume aux colis de gros volume de différentes formes et avec des exigences de performances et des temps de mesure admissibles différents) ne permet pas de donner des préconisations spécifiques pour tous les scénarios possibles. L'objectif de l'ISO 19017:2015 est donc d'établir un ensemble de principes directeurs. En définitive, la mise en ?uvre doit être assurée par du personnel dûment qualifié et expérimenté, et être fondée sur une bonne compréhension des facteurs d'influence, des variables à prendre en compte et des exigences de performances de l'application de mesurage considérée.
L'ISO 19017:2015 a été élaborée selon l'hypothèse que le besoin de fournir un tel système a été dûment examiné et que ses exigences d'application et de performances ont été dûment définies selon un processus de collecte des exigences structuré, tel que les objectifs de qualité des données (DQO).
L'attention est portée sur le fait que, bien que cela ne relève pas du domaine d'application de l'ISO 19017:2015, nombre des principes, méthodes de mesure et pratiques recommandées décrits dans le présent guide s'appliquent également aux mesurages gamma réalisés sur des éléments autres que les déchets radioactifs (ex. aliments en vrac, eau, matériaux en vrac) ainsi qu'aux mesurages réalisés sur des matières radioactives contenues dans des colis non traditionnels (ex. dans des conteneurs de transport).
Navodilo za merjenje aktivnosti radioaktivnih odpadkov z gama spektrometrijo (ISO 19017:2015)
Standard ISO 19017:2015 se uporablja za merjenje sevanja gama žarkov radioaktivnih odpadkov.
Radioaktivni odpadki so lahko različnih oblik in imajo različne lastnosti, pri čemer so vključeni:
– neobdelani ali nekondicionirani odpadki, vključno s procesnimi odpadki (filtri, smole, krmilni drogovi, odpadna kovina itd.) in odpadki, ki nastanejo pri razstavljanju ali izločitvi iz uporabe;
– kondicionirani odpadki različnih oblik in matric (bitumen, cement, hidravlično vezivo itd.);
– odpadki z zelo nizko radioaktivnostjo (VLLW), nizko radioaktivnostjo (LLW), srednjo radioaktivnostjo (ILW) in visoko radioaktivnostjo (HLW);
– embalaže različnih oblik: cilindrične, kockaste, paralelpipedne itd.
Podane so smernice v zvezi z uvajanjem, umerjanjem in nadzorom kakovosti. Raznolikost načinov uporabe in realizacij sistemov (od raziskovalnih do industrijskih sistemov z različnimi zahtevami glede zmogljivosti in dovoljenim časom merjenja za različne odpadke, od odpadkov z zelo nizko radioaktivnostjo do odpadkov z visoko radioaktivnostjo, ter embalaže, od embalaž majhne prostornine do embalaž velike prostornine različnih oblik) onemogoča oblikovanje posebnih smernic za vse primere. Namen tega mednarodnega standarda je torej oblikovati niz vodilnih načel. Uvajanje mora temeljiti na podrobnem razumevanju dejavnikov, vplivnih spremenljivk in zahtev glede zmogljivosti določene meritve, izvesti pa ga mora ustrezno usposobljeno in izkušeno osebje.
Ta mednarodni standard predpostavlja, da je potreba po zagotavljanju takega sistema ustrezno premišljena ter da so bile uporaba in zahteve glede zmogljivosti sistema ustrezno opredeljene z uporabo strukturiranega postopka za določanje zahtev, kot je določanje ciljev glede kakovosti podatkov (DQO).
Upoštevati je treba, da se številna načela, merilne metode in priporočene prakse, ki so opisani v tem mednarodnem standardu, vendar ne spadajo na področje njegove uporabe, lahko uporabijo tudi za merjenje sevanja gama žarkov snovi, ki niso radioaktivni odpadki (npr. hrana v večjih količinah, voda, samostojni materiali) ali za meritve, opravljene na radioaktivnih materialih, vsebovanih v neobičajnih embalažah (npr. v transportnih zabojnikih).

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
