A fundamental result in metabolic pathway analysis statesthat every flux mode can be decomposed into a sum of elementary modes.However, only a decomposition without cancelations is biochemically meaningful,since a reversible reaction cannot have ...

Geologic, seasonal, and atmospheric predictors of indoor home radon values
Exposure to tobacco smoke and radon cause lung cancer. Radioactive decay of naturally occurring uranium in bedrock produces radon. Seasonality, bedrock type, age of home, and topography have been associated with indoor radon, but the research is mixed ...

Nanoaerosols Including Radon Decay Products in Outdoor and Indoor Air at a Suburban Site
Nanoaerosols have been monitored inside a kitchen and in the courtyard of a suburban farmhouse. Total number concentration and number size distribution (5–1000 nm) of general aerosol particles, as measured with a Grimm Aerosol SMPS+C 5.400 instrument ...

Contribution of Radon and Radon Daughters to Respiratory Cancer [PDF]
This article reviews studies on the contribution of radon and radon daughters to respiratory cancer and proposes recommendations for further research, particularly a national radon survey. The steady-state outdoor radon concentration averages 200 pCi/m3, and indoor levels are about 4 times higher.

Radon is a carcinogenic factor, but the effects of the potential carcinogenicity of radon progeny on the human body during the prenatal period have not yet been explored. Based on data regarding the half-lives of radon-222 and radon-220 and their progeny, this paper considers their potential effects on the human body in the prenatal period.

Mutagenicity of radon and radon daughters [PDF]
The objective of our research is to investigate the dose-response relationship of the lethal and mutagenic effects of exposure of cells to radon and its decay products. Dose rate dependence and the nature of the DNA lesion will be studied, using the thymidine kinase and HPRT loci to measure mutation frequency.

The physical characteristics of radon are reported as well as its sources,the transport in rock and its behaviour in caves. Then,the instruments,both active and passive, used for the measurement of radon concentration are discussed by taking into accounttheir respective advantages and disadvantages for the use in the cave environment.
