It is then subjected to heating under defined conditions. The…

Specifies the characteristics of reference sources and reference radiations which take the form of adequately characterized large-area sources specified in terms of activity (per unit area) and surface emission rate. Regulatory documents refer to surface contamination in terms of activity per unit area, while the response of monitoring instruments is related directly to the radiation emitted (i.e…

Presents guidance for carrying out manipulations which are common to each technique for the microbiological examination of water, particularly the preparation of samples, culture media and apparatur. It also describes the various enumeration methods available and the criteria for the choice of a particular technique.

La présente Norme internationale spécifie les caractéristiques de sources de référence, traçables à des étalons nationaux de mesurage, permettant l'étalonnage des moniteurs de contamination de surface. Elle se rapporte aux émetteurs alpha et aux émetteurs bêta dont l'énergie bêta maximale est supérieure à 0,15 MeV. Elle ne décrit pas les modes opératoires qu'implique l'…
