Measurement strategy to study radon source, entry and dilution rates in energy-efficient buildings in Russia

Abstract

Main physical quantities, which control indoor radon in modern energy-efficient buildings of Russia was studied basing on the results of radon survey in Ekaterinburg, Russia. It was approved that measures to increase energy efficiency lead to reduction in the ventilation rate and high accumulation of radon concentrations indoors. Long-term measurements with application of proposed mathematical methods give an improved understanding of the radon entry processes. Combined use of integrative and time series (differential) measurements provides effective way to develop standard protocol for radon measurements in energy-efficient multi-storey buildings.
