Remedial measures to prevent soil gas infiltration have been implemented on many buildings affected by intrusion of radon, water vapour, methane and other volatile organic compounds (VOCs ). The success of these measures has been well documented for gases such as radon; however similar detailed documentation was not readily available for methane or other vocs. The objective of this study was to evaluate the effectiveness of four different remedial solutions installed on houses. All houses tested in this study had the potential of methane intrusion.
The aim of this study was to compare the radon levels at workplaces and in homes located nearby. Homes (number of 57) and partly or fully underground workrooms (number of 55) have been studied at the four workplaces in southern Finland and one workplace in northern Finland. Radon concentrations both at workplaces and in homes seemed to be at the same level in the same district. The mean radon concentration in workrooms was 406 Bq.m³, and in homes concentration was 398 Bq.m³.
