b) la description des différentes catégories des programmes de surveillance;
c) les critères quantitatifs pour la conduite des programmes de surveillance;
d) les méthodes de surveillance appropriées et les critères de sélection;
e) les informations à collecter pour la conception d’un programme de surveillance;
f) les exigences générales pour les programmes de surveillance (par exemple, limite de détection, incertitudes tolérées);
g) les fréquences des mesurages calculées en se basant sur la série de rapports de la CIPR «Occupational Intakes of Radionuclides (OIR)»;
h) la surveillance individuelle dans certains cas (incorporation d’actinides, incorporation par plaie et incorporation à travers la peau intacte);
i) l’assurance qualité;
j) la documentation, la transmission et l’archivage des résultats.
Le présent document ne s’applique pas:
— à la surveillance de l’exposition au radon et à ses produits de filiation radioactifs;
— aux descriptions détaillées des méthodes et des techniques de mesurage;
— aux modes opératoires détaillés pour les mesurages in vivo et les analyses in vitro;
— à l’interprétation des résultats de mesure en termes de doses;
— aux données biocinétiques et aux modèles mathématiques pour convertir les activités mesurées en dose absorbée, en dose équivalente et en dose efficace;
— à l’investigation des causes ou des implications d’une exposition ou d’une incorporation.
