LoginThe Austrian Standard ÖNORM S 5200, prepared in the early nineties after a prestandard phase (Steger F.) and in use in Austria since 1996, provides the criteria to assess the radiation dose of building materials.
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.
A radon Test-House was realised and equipped with an Active Sub-Slab Depressurization (ASD)system to test and quantify its performance as a radon remediation measure. As active element, acentrifugal fan of power 136 W was used.
A test-house was realised and equipped with an Active Sub-Slab Depressurization (ASD) systemwith two suction branches. As the active element, a centrifugal fan of power 136 W was used.
Soil radon concentrations together with climatic and seismic data were continuously observed in theKanto area (Japan). During fall 1998, several typhoons and earthquakes occurred.
Various methods to determine ²²²Rn concentration in soil gas were tested at two sites with different soil types in a depth of 1 m.
There is a currently growing interest in the effect of exposure to 222Rn, because it became recognised as an important “pollutant” factor of the environment.
Three different methods were used to measure radon concentration in groundwater near Baia Mare andin other places of touristic interest from Maramures, the northest district of Romania.
Historic low-level radioactive wastes are located in Port Hope, Ontario, Canada.
The International Commission on Radiological Protection (ICRP) recommends the use of a singleconversion factor, derived from epidemiological studies of exposure to uranium miners, for thedetermination of the effective dose from inhalation of radon
Two methods for determining the 222Rn diffusion coefficient in building materials are presented.Experimentally, the measurement of radon release rates under well-controlled conditions, using aflush and adsorption technique, underlies both methods.
The use of two mapping methods, kriging and moving average, in mapping the indoor radon risk, isinvestigated.
Measurements of indoor radon (222Rn) concentrations were carried out by using LR-115 II solid statenuclear track detectors (SSNTD).
In 1986 The State of New Jersey embarked on a program that would enable the characterization ofthe State's indoor radon problem.
This paper presents a history of the development of a formalized training and technology transferprogram for radon testers and mitigators in the United States.
First, models (room models) published in the international literature allowing the exposure togamma radiation indoors due to building materials to be assessed are reviewed and discussed.
Within the Belgian Radon Programme the Belgian Building Research Institute is responsible for theinvestigation of techniques for prevention and mitigation of radon problems in dwellings.
A soil gas measurement method developed earlier [1] was applied to boreholes drilled to belowfoundation depth. Radon concentration and permeability were measured at 50 cm intervals.
It is estimated that more than 5000 householders in the UK have taken steps to reduce high radonlevels in their homes.
A data set of long-term radon measurements in about 2200 houses in southern Belgium has been collectedin an on-going national Rn survey. The spatial variation of indoor Rn concentrations is modelled byvariograms.
The relation between an increased risk for lung cancer and exposure to indoor radon is assessed inepidemiological studies. Both the quality and reliability of smoking data and the radon exposuredata are of primary importance.
