Water quality - Lead-210 - Test method using liquid scintillation counting (ISO 13163:2013)
ISO 13163 specifies the determination of lead-210 (210Pb) activity concentration in samples of all types of water using liquid scintillation counting (LSC). For raw and drinking water, the sample should be degassed in order to minimize the ingrowth of 210Pb from radon-222 (222Rn).
Using currently available liquid scintillation counters, this test method can measure the 210Pb activity concentrations in the range of less than 20 mBq⋅l-1 to 50 mBq⋅l-1. These values can be achieved with a counting time between 180 min and 720 min for a sample volume from 0,5 l to 1,5 l.
Higher 210Pb activity concentrations can be measured by either diluting the sample or using smaller sample aliquots or both.
It is the laboratory's responsibility to ensure the suitability of this test method for the water samples tested.
Wasserbeschaffenheit - Blei-210 - Verfahren mit dem Flüssigszintillationszähler (ISO 13163:2013)
ISO 13163 legt die Bestimmung der Blei 210(210Pb)-Aktivitätskonzentration in Proben aller Wasserarten mit dem Flüssigszintillationszähler (LSC) fest. Im Fall von Roh und Trinkwasser sollte die Probe entgast werden, um den Einwuchs von 210Pb aus Radon 222 (222Rn) auf ein Minimum zu beschränken.
Bei Verwendung der derzeit verfügbaren Flüssigszintillationszähler können mit diesem Prüfverfahren die 210Pb Aktivitätskonzentrationen im Bereich von weniger als 20 mBq ⋅ l−1 bis 50 mBq ⋅ l−1 gemessen werden. Diese Werte lassen sich bei einer Messdauer zwischen 180 min und 720 min bei einem Probenvolumen von 0,5 l bis 1,5 l erreichen.
Höhere 210Pb Aktivitätskonzentrationen können entweder durch Verdünnen der Probe oder Verwenden kleinerer Probenaliquote oder beides gemessen werden.
Es liegt in der Verantwortung des Labors, die Eignung dieses Prüfverfahrens für die zu prüfenden Wasserproben sicherzustellen.
Qualité de l'eau - Plomb 210 - Méthode d'essai par comptage des scintillations en milieu liquide (ISO 13163:2013)
L'ISO 13163:2013 spécifie la détermination de l'activité volumique du plomb 210 dans des échantillons de tout type d'eau par comptage en scintillation liquide (CSL). Pour les eaux brutes et les eaux potables, il convient que l'échantillon soit dégazé afin de limiter la re-croissance du plomb 210 à partir du radon 222 .
À l'aide d'un compteur à scintillation liquide standard, cette méthode d'essai peut mesurer les valeurs d'activité volumique du plomb 210 sur un domaine allant de moins de 20 mBq/l à 50 mBq/l. Ces valeurs peuvent être atteintes avec un temps de comptage compris entre 180 min et 720 min pour une prise d'essai de 0,5 l à 1,5 l.
Des valeurs plus élevées d'activité volumique du plomb 210 peuvent être mesurées en effectuant une dilution de l'échantillon et/ou en utilisant des aliquotes plus petites.
Kakovost vode - Svinec Pb-210 - Preskusna metoda s štetjem s tekočinskim scintilatorjem (ISO 13163:2013)
ISO 13163 določa metodo za določevanje koncentracije aktivnosti svinca 210 (210Pb) v vzorcih vseh vrst vode s štetjem s tekočinskim scintilatorjem (LSC). Pri neobdelani in pitni vodi mora biti vzorec razplinjen za zmanjševanje vsebnosti svinca 210 iz radona 222 (222Rn).
S števci s tekočinskim scintilatorjem lahko s to preskusno metodo izmerite koncentracijo aktivnosti svinca 210 v razponu od manj kot 20 mBq⋅l-1 do 50 mBq⋅l-1. Te vrednosti se lahko dosežejo v času štetja med 180 in 720 min za količino vzorca od 0,5 do 1,5 l.
Višje koncentracije aktivnosti svinca 210 se lahko izmerijo z redčenjem vzorca ali raztopinami manjših vzorcev ali obojim.
Laboratorij mora zagotoviti primernost te preskusne metode za vzorce vode, ki se preskušajo.

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.

Introduction
Radioactivity from several naturally occurring and anthropogenic sources is present throughout the
environment. Thus, water bodies (e.g. surface water, groundwater, seawater) can contain the following
radionuclides of natural or human-made origins:
— natural radionuclides, including potassium-40, and those originating from the thorium and uranium
decay series,
