Measurement of radioactivity in the environment - Soil - Part 4: Plutonium 238 and plutonium 239 + 240 - Test method using alpha spectrometry (ISO 18589-4:2019)
This document describes a method for measuring 238Pu and 239 + 240 isotopes in soil by alpha spectrometry samples using chemical separation techniques.
The method can be used for any type of environmental study or monitoring. These techniques can also be used for measurements of very low levels of activity, one or two orders of magnitude less than the level of natural alpha-emitting radionuclides.
The test methods described in this document can also be used to measure the radionuclides in sludge, sediment, construction material and products following proper sampling procedure[2][3][4][5][7][8].
The mass of the test portion required depends on the assumed activity of the sample and the desired detection limit. In practice, it can range from 0,1 g to 100 g of the test sample.
Ermittlung der Radioaktivität in der Umwelt - Erdboden - Teil 4: Messung von Plutonium-238 und Plutionium-239 + 240 - Messverfahren mit Alphaspektrometrie (ISO 18589-4:2019)
Dieses Dokument legt ein Verfahren für die Messung der Plutoniumisotope 238 und 239 + 240 in Proben von Erdboden durch Alphaspektrometrie unter Anwendung chemischer Trenntechniken fest.
Dieses Verfahren kann für jede Art von Umweltstudien oder zur Umweltüberwachung angewendet werden. Diese Techniken können außerdem für Messungen sehr geringer Aktivitätspegel genutzt werden, die eine oder zwei Größenordnungen niedriger sind als die Alphaemissionspegel von natürlichen Radionukliden.
Die in diesem Dokument beschriebenen Prüfverfahren können bei Befolgung eines ordnungsgemäßen Pro¬benahmeverfahrens auch für die Messung der Radionuklide in Schlamm, Sediment, Baustoffen und pro¬dukten verwendet werden [2], [3], [4], [5], [7], [8].
Die erforderliche Masse der Prüfmenge hängt von der angenommenen Aktivität der Probe und der gewünschten Nachweisgrenze ab. In der Praxis können Prüfproben von 0,1 g bis 100 g verwendet werden.
Mesurage de la radioactivité dans l'environnement - Sol - Partie 4: Plutonium 238 et plutonium 239 + 240 - Méthode d'essai par spectrométrie alpha (ISO 18589-4:2019)
Le présent document spécifie une méthode de mesure des isotopes du 238Pu et du plutonium 239 + 240 dans le sol, par spectrométrie alpha à l'aide de techniques de séparation chimique.
La méthode peut être utilisée pour tout type d'étude ou de contrôle de l'environnement. Ces techniques peuvent également être utilisées pour le mesurage de niveaux d'activité très faibles, à savoir un ou deux ordres de grandeur inférieurs au niveau de radionucléides émetteurs alpha naturels.
Les méthodes d'essai décrites dans le présent document peuvent également être utilisées pour mesurer les radionucléides dans une boue, dans un sédiment, dans un matériau de construction et dans des produits de construction en suivant un mode opératoire d'échantillonnage approprié[2][3][4][5][7][8].
La masse de la prise d'essai dépend de l'activité prévue de l'échantillon et de la limite de détection requise. Dans la pratique, elle peut être constituée de 0,1 g à 100 g de l'échantillon pour essai.

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
