Water quality - Measurement of gross alpha and gross beta activity in non-saline water - Thin source deposit method (ISO 10704:2009)
ISO 10704:2009 specifies a method for the determination of gross alpha and gross beta activity in non‑saline waters for alpha- and beta‑emitting radionuclides.
The method is applicable to raw and potable waters containing a small quantity of dissolved matter. It can, after adaptation, apply to other kind of waters.
The range of application depends upon the amount of dissolved material in the water and on the performance characteristics of the measurement equipment (background count rate and counting efficiency).

L'ISO 10704:2009 spécifie une méthode pour la détermination des activités alpha globale et bêta globale des eaux non salines pour des radionucléides émetteurs alpha et bêta.
La méthode est applicable aux eaux brutes et aux eaux potables peu chargées en matières dissoutes. Elle peut, après adaptation, s'appliquer à d'autres types d'eaux.
Le domaine d'application dépend de la quantité de matières dissoutes dans l'eau et des caractéristiques de performance de l'équipement de mesurage (taux de comptage du bruit de fond et rendement de comptage).
Kakovost vode - Merjenje skupne alfa in skupne beta aktivnosti v neslanih vodah - Metoda depozicije v tankem sloju (ISO 10704:2009)
Ta mednarodni standard opisuje metodo za določevanje skupne alfa in beta aktivnosti v neslanih vodah za alfa in beta oddajne radionuklide. Metoda se uporablja za neobdelane in pitne vode z majhno količino raztopljenih snovi. Po prilagoditvi se lahko uporablja za druge vrste vode. Območje uporabe je odvisno od količine raztopljenih snovi v vodi in od lastnosti merilne opreme (stopnja štetja v ozadju in učinkovitost štetja).

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.

non-saline waters for alpha- and beta-emitting radionuclides.
The method is applicable to raw and potable waters containing a small quantity of dissolved matter. It can,
after adaptation, apply to other kind of waters.

4 Principle
IMPORTANT — Gross alpha and gross beta determinations are not absolute determinations of the
sample alpha and beta radioactive contents, but relative determinations referred to specific alpha and
beta emitters that constitute the standard calibration sources.
In order to obtain a thin deposit directly on a planchet, the sample can be progressively evaporated to dryness
