The NRPI integral system for measurement of an average air exchange rate in buildings

Popis výsledku v původním jazyce

The air exchange rate between indoor and outdoor air is the key physical process which influences among other things also behavior of all types of aerosol and gaseous contaminants, including radon gas in buildings and mediates their transport from the outside air to the interiors of buildings. Hence, measurement of the air exchange rate plays the important role for dose assessment also from inhalation of radon gas in buildings. A several years ago, a new technique and method for determination of an average air exchange rate in buildings (apartments, multiple storey family houses, kindergartens, etc.) have been developed atthe National Radiation Protection Institute of Prague (NRPI). Recently, the method has been certified by the highest relevant Czech state authority – the State Office for Nuclear Safety. Currently, both the method and the technique are used in practice in the frame of the Czech National action plane in accordance with an applicable legislation. After introduction of the self technique, some examples of its use in field and the most interesting results will be presented. Generally, the technique allows wide-spread survey in buildings and estimation of the air exchange rate ranging from 0.05 h-1 to approx. 3 h-1 within exposition duration lasting from a several days up to a several months with a total uncertainty about 30 %. Presented at RAD 2018: Sixth International Conference on Radiation and Applications in Various Fields of Research: book of abstracts. Niš: RAD Association, 2018, s. 219. ISBN 978-86-80300-03-0.
