Publicly available information about radon potential in Northern Ireland is currently based on indoor radon results averaged over 1-km grid squares, an approach that does not take into account the geological origin of the radon. This study describes a spatially more accurate estimate of the radon potential of Northern Ireland using an integrated radon potential mapping method based on indoor ra...

A survey was undertaken of radon levels in 1013 dwellings in Sussex, UK. A number of dwellings were identified with high radon levels in an area previously considered to offer low radon risk from geological sources. Multiple regression was used to determine the relative influence of the various geographical and building-related factors on indoor radon levels. The radon hazard, independent of bu...

Radon mitigation by natural basement ventilation was compared to mitigation by forced ventilation (pressurization) and to mitigation by the operation of a modified heating and air conditioning (HAC) system in a series of experiments conducted during the spring and summer in a research house. Both natural ventilation and basement pressurization reduced average basement radon concentrations from ...

results the mean radon concentration in the drinking water of aliabad katoul is 2.90 ± 0.57 bq/l. conclusions the radon concentration in aliabad katoul is below the limit for hazardous levels, but some precautions will make conditions even safer for the local populace. objectives the aim of this study is to evaluate the concentration of soluble radon in the drinking water of the city of aliabad...

background: radon is the second leading cause of lung cancer after smoking. in canada, the health authorities have no access to comprehensive profile of the communities built over uranium-rich micro-geological settings. the present indoor radon monitoring guideline is unable to provide an accurate identification of health hazards due to discounting several parameters of housing characteristics....

Within the United States, the national standard for radon measurements is embodied in a primary radon measurement system that has been maintained for over 50 years to accurately measure radon (222Rn) against international and national radium (226Ra) standards. In turn, all of the radon measurements made at the National Institute of Standards and Technology (NIST) and the radon transfer calibrat...

Radon-222 (also known as radon) is a relatively long-lived isotope of radon and originates from uranium present in the earth's crust. Radon-220 (also known as thoron) is a short-lived isotope of radon and originates from thorium present in the earth's crust. Fundamental properties and health hazards of these gases are compared. On the average, the thoron contribution to the total dose to the lu...

Radon is one of the most important radioactive gases.Radon emits alpha particles and ultimately,it can cause genetic disorders.There are many reports of carcinogenesis and its harmful effects.One way to get this gas into the body is by eating and drinking.In the meantime,milk is one of the most consuming foods that can be contaminated with radon.In this study, the concentration of radon gas was...

the presence of radon in drinking water causes health risks associated with exposure from both inhalation and ingestion. since the studies show that faults near the water resources have a critical effect on the concentration of radon, kouhbanan active fault zone, to find water resources  with high radon concentration was chosen for the following investigation. water samples were taken from all ...
