A statistical evaluation of the geogenic controls on indoor radon concentrations and radon risk

Journal of Environmental Radioactivity, 2010
ANOVA is used to show that approximately 25% of the total variation of indoor radon concentrations in England and Wales can be explained by the mapped bedrock and superficial geology. The proportion of the total variation explained by geology is higher (up to 37%) in areas where there is strong contrast between the radon potential of sedimentary ...

RADON CONCENTRATIONS IN ELEMENTARY SCHOOLS IN KUWAIT

Health Physics, 2006
Measurements of indoor radon concentrations were performed in 25 classrooms in the capital city of Kuwait from September 2003 to March 2004 using track etch detectors. The investigation was focused on area, ventilation, windows, air conditioners, fans, and floor number. All the schools have nearly the same design.

The Use of Computed Radon Entry Rates to Understand Radon Concentration in Buildings

Health Physics, 1994
The central role played by basement depressurization in drawing radon-contaminated soil gas into a structure has been demonstrated by calculating the radon entry rate from radon concentration and air infiltration measurements at different levels of basement depressurization in a single-family research house. The radon entry rate is found to be a linear

Measurement of radon concentration in water using the portable radon survey meter

Radiation Protection Dosimetry, 2011
A measurement method for measuring radon in water using the portable radon survey meter (RnSM) was developed. The container with propeller was used to stir the water samples and release radon from the water into the air in a sample box of the RnSM. In this method, the measurement of error would be 20 Bq l(-1).

Variations in radon-222 concentrations

Journal of Radiological Protection, 1988
Concentrations of radon-222 can vary widely both indoors and out of doors. Some of the causes of the variations are unpredictable, but diurnal and seasonal patterns of variation can be discerned if radon fluctuations are averaged out. The average diurnal variation in radon concentration out of doors has been shown to follow the average pattern of ...

The “Tolerance Concentration” of Radon in the Atmosphere

The British Journal of Radiology, 1939
Reasons are given for suspecting that radon in the atmosphere may be responsible for leucopœnia among radium workers. The radon concentrations measured in air samples taken from several radium laboratories are given. Mice have been kept in very low radon concentrations, and the effects on them are described. It is suggested that 10−11 curies/c.c.

Survey of radon concentrations in Dutch dwellings.

The Science of the total environment, 1985
A survey of radon concentrations in Dutch dwellings reveals a median value of 24 Bq/m3, while no excessive high values were observed. Correlations between radon concentration and (combinations of) building parameters will be presented and discussed in terms of the various sources of indoor radon.

Indoor radon concentrations in kindergartens

Journal of Environmental Radioactivity, 1993
Abstract Indoor radon concentrations in the kindergartens of Osijek were measured with alpha-scintillation cells, LR-115 nuclear track detectors, as well as a Radhome semiconductor detector and average values of 50.2, 43.7 and 47 Bq m−3 were obtained respectively.
