LoginThe study aims at measuring the gamma activity concentration (226Ra, 232Th and 40K) of sub-slabfilling gravel of Finnish houses.
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.

The short-lived decay product (Rn-d) of radon gas (222Rn, 220Rn) have been identified as a healthhazard in occupational exposure situations.
In recent years a number of case-control epidemiological studies have taken place and others are inprogress to evaluate the lung cancer risk to the general population from exposure to radon and itsshort-lived progeny in the indoor residential envi
Possibilities for harmonising controls on the radioactivity of building materials within the EuropeanUnion are being discussed in the Working Party on Natural Radiation Sources established by theArticle 31 Group of Experts (Euratom Treaty).
In situ gamma spectroscopy is widely utilised to determine the outdoor gamma dose rate from the soiland to calculate the natural and artificial radionuclide concentration and their contribution to the doserate.
Seasonal variation of radon concentration - measurements in some european countries | 1999 | English
The radon concentrations in indoor air and in soil air vary both on short term (daily, weekly) and onlong term (seasonal).
A dwelling in M?traderecske in the Hungarian north-east region was selected to study the radon daughter (RD) behaviour in a family room with natural low ventilation under living conditions.
In the last twenty years the interest of the international scientific community on naturally occurring radioactive materials (NORM) in the environment and industry has been ever growing.
Radon goes through four stages from its formation until it reaches a living environment: i) itsgeneration in the source medium, ii) its migration in the source medium, iii) its entry into a dwelling,and iv) its accumulation indoors.
The application of a radon model is useful to understand the processes that drive the radon gasbehaviour from its sources to its accumulation indoors.
A method is developed to measure 222Rn exhalation rate on soil surfaces using an ionizationchamber radon monitor (AlphaGUARD PQ2000, Genitron Instruments GmbH, Frankfurt,Germany) in passive-diffusion mode.We have developed a compartmental model to
Rad Elec Inc., located in Frederick, MD, USA is the only commercial producer of electret ionchambers (EIC) systems. These are distributed under the brand name of E-PERM, electret-passiveenvironmental radon monitors.
