ČSN EN ISO 11665-2   (404013) Měření radioaktivity v životním prostředí - Vzduch: radon 222 - Část 2: Integrální metoda měření průměrné koncentrace latentní energie krátkodobých produktů přeměny radonu

Anotace textu normy ČSN EN ISO 11665-2   (404013)

This part of ISO 11665 describes integrated measurement methods for short-lived radon-222 decay products[4]. It gives indications for measuring the average potential alpha energy concentration of short-lived radon-222 decay products in the air and the conditions of use for the measuring devices.

This part of ISO 11665 covers samples taken over periods varying from a few weeks to one year. This part of ISO 11665 is not applicable to systems with a maximum sampling duration of less than one week.

The measurement method described is applicable to air samples with potential alpha energy concentration of short-lived radon-222 decay products greater than 10 nJ/m3 and lower than 1 000 nJ/m3.
