BACKGROUND Radon is the second risk factor for lung cancer after tobacco consumption and therefore it is necessary to know the burden of disease due to its exposure. The objective of this study is to estimate radon-attributable lung cancer mortality in Galicia, a high emission area located at the Northwest Spain. METHODS A prevalence-based attribution method was applied. Prevalence of tobacco...

background: radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. the presence of radon gas is common, wherever those faults are located there. radon concentration of various drinking water resources of bam villages; located near bam fault; was measured. materials and methods: this cross-sectional study was cond...

introduction recent studies of public underground parking lots showed the influence of radon concentration and the probable discomfort caused by parking cars. materials and methods radon concentration was measured in semi-closed public parking lots in the six governorates of kuwait, using durridge rad7radon detector (usa). results the peak radon concentration in the parking lots of kuwait gover...

This study sought to determine the effect of environmental conditions on radon levels in a home. The two independent variables in the experiment were (1) whether or not it was raining and (2) whether the HVAC system on the main level of the home was set to “ON” for continuous ventilation or “AUTO” for forced air only to maintain temperature. A recently calibrated Radalink AirCat® radon detector...

As information on indoor air quality accumulated* it became apparent that radon and its progeny are invariably present in indoor environments and that concentrations may reach unacceptably high levels. The lung cancer excess anong miners exposed to radon progeny raised concern that exposure to radon progeny might also cause lung cancer in the general population. This presentation first provides...

(222)Rn concentrations in drinking water samples from Beijing City, China, were determined based on a simple method for the continuous monitoring of radon using a radon-in-air monitor coupled to an air-water exchanger. A total of 89 water samples were sampled and analyzed for their (222)Rn content. The observed radon levels ranged from detection limit up to 49 Bq/L. The calculated arithmetic an...

The continuous soil gas radon and daily monitoring of radon concentration in water is carried out at Amritsar (Punjab, India), a well known seismic zone to study the correlation of radon anomalies in relation to seismic activities in the study area. In this study, radon monitoring in soil was carried out by using barasol probe (BMC2) manufactured by Algade France whereas the radon content in wa...

In recent years, a number of case-control epidemiological studies have taken place and others are in progress to evaluate the lung cancer risk to the general population from exposure to radon and its short-lived progeny in the indoor residential environment. While it is actually long term exposure over past decades to radon progeny by inhalation that dominates lung doses, for a number of practi...

The radon isotopes (Rn-222 and Rn-220) and their progenies are responsible for more than 50% of natural radiation dose and the second leading factor in the case of the development of lung cancer after smoking [1]. Rn-222 (radon) and Rn-220 (thoron) are generated in crustal materials from their natural Ra-226 (U-238 decay series) and Ra-224 (Th-232 decay series) content, respectively. As a resul...
