Measurement of radioactivity in the environment - Air: radon-222 - Part 1: Origins of radon and its short-lived decay products and associated measurement methods (ISO 11665-1:2012)
ISO 11665-1:2012 outlines guidance for measuring radon-222 activity concentration and the potential alpha energy concentration of its short-lived decay products in the air.
The measurement methods fall into three categories:
spot measurement methods;
continuous measurement methods;
integrated measurement methods.
ISO 11665-1:2012 provides several methods commonly used for measuring radon-222 and its short-lived decay products in air.
ISO 11665-1:2012 also provides guidance on the determination of the inherent uncertainty linked to the measurement methods described in its different parts.

L'ISO 11665-1:2012 présente les lignes directrices pour le mesurage de l'activité volumique du radon 222 et de l'énergie alpha potentielle volumique de ses descendants à vie courte dans l'air.
Les méthodes de mesure se divisent en trois catégories:
méthodes de mesure ponctuelle;
méthodes de mesure en continu;
méthodes de mesure intégrée.
L'ISO 11665-1:2012 fournit plusieurs méthodes couramment utilisées pour le mesurage du radon 222 et de ses descendants à vie courte dans l'air.
L'ISO 11665-1:2012 fournit également des lignes directrices relatives à la détermination de l'incertitude relative aux méthodes de mesure décrites dans ses diverses parties.
Merjenje radioaktivnosti v okolju - Zrak: radon-222 - 1. del: Radon in njegovi kratkoživi razpadni produkti: izvori in merilne metode (ISO 11665-1:2012)
ISO 11665-1:2012 navaja smernice za merjenje koncentracije aktivnosti radona-222 in potencialne koncentracije alfa energije njegovih kratkoživih razpadnih produktov v zraku. Merilne metode so razdeljene v tri kategorije: – metode točkovnega merjenja; – metode neprekinjenega merjenja; – metode integriranega merjenja. ISO 11665-1:2012 določa več metod, ki se običajno uporabljajo za merjenje radona-222 in njegovih kratkoživih razpadnih produktov v zraku. ISO 11665-1:2012 določa tudi smernice za ugotavljanje temeljne negotovosti v povezavi z merilnimi metodami, opisanimi v različnih delih tega standarda.

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.
ISO 11665-1 was prepared by Technical Committee ISO/TC 85, Nuclear energy, nuclear technologies, and
radiological protection, Subcommittee SC 2, Radiological protection.
ISO 11665 consists of the following parts, under the general title Measurement of radioactivity in the
environment — Air: radon-222:
