Czech primary radon measurement equipment

Abstract

The Authorized Metrological Centre (AMS) working by SUJCHBO (National Institute for Nuclear, Chemical and Biological Protection) ensures for the Czech Republic the metrological traceability for devices that measure the radon concentration and the energy equivalent radon concentration connected with the radon decay products (RnDP). The evaluation and the calibration of measuring devices for radon and RnDP require the stable conditions (first of all radon and the RnDP concentrations). The new AMS radon-aerosol chamber in Kamenná consists of the walk-in testing chamber with a volume of 10 m(3) and of the handling box with a volume of 0.3 m(3). The design of the chamber allows measurement and a control of environmental parameters such as the temperature, the pressure of air inside and outside of the chamber, the relative humidity of air, the concentration and the size distribution of aerosol particles and the air velocity.

“…It is also possible for the created aerosol particles to be sampled and measured externally. The RAC parameters are described by Burian [4].…”

“…Radono dujos susidaro įvairių tipų uolienose ir dirvože-miuose (Burian et al 2011). Daugiausia radono dujų yra molyje (10-120 kBq/m 3 ), o mažiausia -žvyre ir stambiame smėlyje (4-20 kBq/m 3 ) (Abromaitytė et al 2003).…”
