ČSN EN ISO 11665-1   (404013) Měření radioaktivity v životním prostředí - Vzduch: radon 222 - Část 1: Původ radonu a krátkodobých produktů přeměny radonu a s nimi spojené měřicí metody

Anotace textu normy ČSN EN ISO 11665-1   (404013)

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.
