LoginA number of interzonal models have been developed to calculate air flows and pollutant transport mechanisms in both single and multizone buildings.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Radon as an indoor air pollutant has been extensively researched worldwide over the past thirtyyears. However, radon is only one of several other important pollutants present in the indooratmosphere.
If indoor radon levels are to be significantly reduced across Europe it is essential to ensure that allnew buildings built in areas affected by radon are protected against radon.In the United Kingdom the Building Research Establishment Ltd (BRE) h
This study describes an approach for measuring and modeling diffusive and advective transport of radon through building materials.
Indoor 222Rn concentrations are influenced by several factores which may change with time,thereby causing temporal fluctuations of radon concentrations in rooms.
Electret ion chamber (EIC) for monitoring radon consists of a stable electret (electrically chargedTeflon disc) mounted inside an electrically conducting chamber. PERM?
A national survey of indoor radon levels in Lithuania was performed between 1995 and 1998.
Radon progeny concentration is measured with a total alpha counting system in 185 dwellings in thetown of Thessaloniki.
A newly built radon calibration test bench called BACCARA is presented. A method of calibrationusing a secondary 222Rn standard is described and examples of calibration are given.
The indoor radon program in the US.
To evaluate the dose arising from exposure to Rn Decay Products (RDP) a term often used isunattached fraction defined as the ratio of the Equilibrium Equivalent Concentration (EEC) arising from unattached radon decay products (URDP) to the total d
Radon gas is now considered to be a health hazard when found in excessive amounts in the builtenvironment. The levels of radon vary greatly, with some geographical areas having very highlevels.
Raised radon gas levels are known to exist in mines and Show Caves, and in the United Kingdomthe Ionising Radiations Regulations 1985 require the employer to take action to reduce radonlevels by improving ventilation or restricting access, because
Passive radon(222Rn) detectors are commonly used for radon surveys. They provide the integrated exposure.
Accurate measurements of the radon flux of real building materials in existing houses with normalor contaminated walls and/or the mean emanation rate of soil samples, raw materials or building materials are very important for certain studies relat
The contents of an Experimental Set are presented, providing all necessary implements for novelmethods to collect, concentrate, store and measure radon and radon decay products from harmless und ubiquitous sources of air, liquids and solids.
Results of an investigation into factors contributing to elevated indoor radon concentrations insupposedly mitigated homes suggest that, in areas of extensive karst geological development,fluctuations in indoor radon concentrations may be extraord
The aim of this study was to compare the measured and the calculated concentrations of indoorradon caused by building materials at 23 workplaces.
In the study, the factors affecting concentrations of radon vertically lines were surveyed in twolarge office buildings.
Radon concentration in a crawl space remained at the same level during autumn ( 756 Bq m-3 ) and inwinter ( 767 Bq m-3 ) because both air exchange rate and negative pressure (measured across thefoundation wall) increased after a installation of a
