Salinity, radon, and radon precursors in the soils of Grand Forks County, North Dakota
<p>High levels of indoor radon have been observed in many areas of the Red River Valley and particularly in Grand Forks County of North Dakota. Data from the University of North Dakota (UND) Radon Monitoring Facility indicated more than 80% of the dwellings tested had radon levels greater than the …

Le radon dans les maisons
Le radon est un gaz noble, inodore et incolore, présent partout dans l'environnement. Il est radioactif, et c'est pour cette raison qu'il est d'une grande importance au niveau de la santé de la population. Il provient de la dégradation de l'uranium et se dégrade aussi de façon radioactive en …

Indoor atmospheric radon in Hamadan, Iran. Atmospheric radon indoors and around Hamadan city in Iran.
Radon gas may be a major air quality hazard issue inside the home. Radon (222Rn) comes from the natural breakdown of radioactive uranium (238U) via radium (226Ra) in soil, rocks, and water. Radon and its progeny contribute more than 50% of the total radiation dose to the human population due to …

Homeowner perception and response to radon
… lung cancer deaths result every year due to radon exposure. Given this, radon education has become an important issue. The purpose of this research was to examine what action consumers had taken to respond to radon as a hazard following an education testing program and why they had taken that …

Nearly Representable Operators (dunford-Pettis, Radon-Nikodym)
In this thesis we introduce the class (DELTA)(X,Y) of nearly represent- able operators from a Banach space X to a Banach space Y. These are the operators that map X-valued uniformly bounded martingales that are Cauchy in the Pettis norm into Y-valued martingales that converge almost everywhere.

Determining the Radon Emanation Coefficient for Soil Samples
Exposure to high concentrations of radon and radon decay products are known to increase lung cancer in humans. This study is in preparation for a national indoor radon survey to be conducted in South Africa. The aim of this study is to determine the radon emanation coefficient for soil samples …

Weak Radon-Nikdoym Sets in Dual Banach Spaces
… theory has long been evident in the study of the Radon-Nikodym property. Recently results of substantial interest in the structure of Banach spaces have been obtained by localizing these ideas to individual subsets. The study of the Radon-Nikodym property for subsets of Banach spaces can be …

Radon, progeny and health: investigation in different environments in Northamptonshire
… this study are that, from a known radium source, radon variability in the environment of the buildings studied is an inevitable consequence of the variability of the prevailing surface boundary layer atmospheric conditions. These influences will be modified by the structural characteristics of the …

Radon remediation: an analysis of dose-reduction, durability and effectiveness
Radon is a colourless, odourless, inert, radioactive gas found in Group 8 of the Periodic Table; it is formed by the decay of uranium in soils and rocks. The half-life of radon is 3.8 days. Radon, in the built environment, is the second largest cause of lung cancer after cigarette smoking and is …

Indoor Concentration Simulation of Radon Isotopes and Their Decay Products
The indoor concentrations of radon isotopes and progeny in indoor air can be viewed as a function of their outdoor concentration, the rate of emanation from inside, ventilation, deposition, and resuspension. Steady-state and time-dependent equations, derived by Thompson, were used to evaluate the …

The Effects of Radon and its Progeny on Human Skin Cells
Radon-222 is a naturally occurring radioactive gas released from granite rock and uranium-rich soil. High levels are found in Southwest England due to local geology. Radon is known to cause lung cancer, therefore its potential role in skin carcinogenesis is of interest, as Southwest England also …

Comprehensive Investigation on Content-based Medical Image Retrieval using Radon Barcodes
… quick search and retrieval of medical images. Radon Barcode (RBC)s are binary complementary feature vectors which increase the speed of CBMIR systems through smaller feature vector size and low retrieval error. We explore further improving the efficiency and accuracy of RBCs by optimizing the …
