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 11665-1:2019)

This document 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:
a)    spot measurement methods;
b)    continuous measurement methods;
c)    integrated measurement methods.
This document provides several methods commonly used for measuring radon-222 and its short-lived decay products in air.
This document also provides guidance on the determination of the inherent uncertainty linked to the measurement methods described in its different parts.

Merjenje radioaktivnosti v okolju - Zrak: radon Rn-222 - 1. del: Radon in njegovi kratkoživi razpadni produkti: izvori in merilne metode (ISO 11665-1:2019)

Standard ISO 11665-1 navaja smernice za merjenje koncentracije aktivnosti radona-222 in potencialne koncentracije alfa energije njegovih kratkoživih razpadnih produktov v zraku. Metode merjenja se razvrščajo v tri kategorije: a) metode točkovnega merjenja; b) metode neprekinjenega merjenja; c) metode integriranega merjenja. Ta dokument določa več metod, ki se običajno uporabljajo za merjenje radona-222 in njegovih kratkoživih razpadnih produktov v zraku. Ta dokument 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.
