Measurement of radioactivity in the environment - Soil - Part 6: Gross alpha and gross beta activities - Test method using gas-flow proportional counting (ISO 18589-6:2019)

This document provides a method that allows an estimation of gross radioactivity of alpha- and beta-emitters present in soil samples. It applies, essentially, to systematic inspections based on comparative measurements or to preliminary site studies to guide the testing staff both in the choice of soil samples for measurement as a priority and in the specific analysis methods for implementation.
The gross α or β radioactivity is generally different from the sum of the effective radioactivities of the radionuclides present since, by convention, the same alpha counting efficiency is assigned for all the alpha emissions and the same beta counting efficiency is assigned for all the beta emissions.
Soil includes rock from bedrock and ore as well as construction materials and products, potery, etc. using naturally occurring radioactive materials (NORM) or those from technological processes involving Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM), e.g. the mining and processing of mineral sands or phosphate fertilizer production and use.
The test methods described in this document can also be used to assess gross radioactivity of alpha- and beta-emitters in sludge, sediment, construction material and products following proper sampling procedure[2][3][4][5][7][8].
For simplification, the term "soil" used in this document covers the set of elements mentioned above.

Ermittlung der Radioaktivität in der Umwelt - Erdboden - Teil 6: Gesamt-Alpha- und Gesamt-Betaaktivitäten - Messverfahren mit Durchfluss-Proportionalzählung (ISO 18589-6:2019)

Dieses Dokument legt ein Verfahren fest, das die Erfassung der gesamten Radioaktivität der in Bodenproben enthaltenen Alpha- und Betaemitter ermöglicht. Es gilt im Wesentlichen für systematische Überprüfungen auf der Grundlage vergleichender Messungen oder lokaler Vorstudien, um dem Prüfpersonal eine Anleitung sowohl für die Auswahl der vorrangig zu messenden Bodenproben als auch für spezifische Analyseverfahren für die Implementierung an die Hand zu geben.
Die Gesamt-Alpha- oder -Betaaktivität unterscheidet sich generell von der Summe der effektiven Aktivitäten der vorhandenen Radionuklide, da per Konvention dieselbe Alphazählausbeute für alle Alphaemissionen und dieselbe Betazählausbeute für alle Betaemissionen zugeordnet ist.
Erdboden beinhaltet sowohl Brocken von Felsgestein und Erz als auch Baustoffe und -produkte, Keramik usw., natürlich vorkommende radioaktive Stoffe (NORM, en: naturally occurring radioactive materials) oder jene aus technologischen Prozessen, die technologisch verbesserte natürlich vorkommende radioaktive Stof¬fe (TENORM, en: Technologically Enhanced Naturally Occurring Radioactive Materials) einbeziehen, z. B. die Förderung und die Verarbeitung von mineralischen Sanden oder die Produktion und Anwendung von Phosphatdüngern.
Die in diesem Dokument beschriebenen Prüfverfahren können bei Befolgung eines ordnungsgemäßen Pro¬benahmeverfahrens auch für die Messung der Gesamt-Alpha- und Gesamt-Betaaktivität von Radionukliden in Schlamm, Sediment, Baustoffen und  produkten verwendet werden [2], [3], [4], [5], [7], [8].
Zur Vereinfachung deckt der Begriff „Erdboden“ im vorliegenden Dokument die vorgenannte Reihe von Ele¬menten ab.

Mesurage de la radioactivité dans l'environnement - Sol - Partie 6: Mesurage des activités alpha globale et bêta globale - Méthode d’essai utilisant un compteur proportionnel à circulation gazeuse (ISO 18589-6:2019)

Le présent document spécifie une méthode d'estimation de la radioactivité globale des émetteurs alpha et bêta présents dans les échantillons de sol. Il s'applique essentiellement aux contrôles systématiques basés sur des mesurages comparatifs ou aux études de site préliminaires destinées à guider le personnel en charge des essais dans le choix des échantillons de sol à mesurer en priorité et des méthodes d'analyse spécifiques à mettre en œuvre.
La radioactivité α ou β globale est généralement différente de la somme des radioactivités effectives des radionucléides présents puisque, par convention, le même rendement de comptage alpha est affecté à toutes les émissions alpha et le même rendement de comptage bêta est affecté à toutes les émissions bêta.
Le sol comprend les roches provenant du socle rocheux et le minerai ainsi que les matériaux et produits de construction, de poteries, etc. utilisant des matières radioactives naturelles (MRN), ou celles résultant de procédés technologiques impliquant des matières radioactives naturelles améliorées technologiquement (MRNAT), par exemple l'exploitation minière et le traitement des sables minéraux ou la production et l'utilisation d'engrais phosphatés.
Les méthodes d'essai décrites dans le présent document peuvent également être utilisées pour évaluer la radioactivité globale des émetteurs alpha et bêta 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].
Pour plus de commodité, le terme « sol » utilisé dans le présent document couvre l'ensemble des éléments susmentionnés.

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
