Radiation from natural sources is one of causes of the environmental diseases. Radon is the leading environmental cause of lung cancer next to smoking. To investigate the relationship between indoor radon concentrations and lung cancer, researchers must be able to estimate an individual's cumulative level of indoor radon exposure and to do so, one must first be able to assess indoor radon conce...

INTRODUCTION The Rn(radon) family is the most significant source of exposure to natural radiation, causing about one-half of the public effective dose. A number of international organizations, including UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation) and ICRP (International Commission on Radiological Protection) have officially reported this fact since the 1980’...

The mechanism and critical conditions of rock failure in underground coal mining processes have attracted great attention. Based on the origin and properties of radon gas, we propose that radon release from underground strata to the surface occurs in two stages, i.e., the formation of free radon and the migration of radon gas. Due to its optimal combination of efficiency and low background meas...

Radon inhalation brings pain relief for chronic constriction injury- (CCI-) induced neuropathic pain in mice due to the activation of antioxidative functions, which is different from the mechanism of the pregabalin effect. In this study, we assessed whether a combination of radon inhalation and pregabalin administration is more effective against neuropathic pain than radon or pregabalin only. M...

Radon therapy using radon (222Rn) gas is classified into two types of treatment: inhalation of radon gas and drinking water containing radon. Although short- or long-term intake of spa water is effective in increasing gastric mucosal blood flow, and spa water therapy is useful for treating chronic gastritis and gastric ulcer, the underlying mechanisms for and precise effects of radon protection...

Radon concentrations and fluxes were measured for seasonal snowpack on Baldpate Mtn. in Newry, Maine during the winter of 2004. A solar radiation and temperature logging system was developed to monitor the snowpack during the radon measurements. Radon ground flux measurements were performed using a RAD-7 alpha spectrometer and ranged from 0.49 to 0.64 pCi m s for two different locations. Radon ...

Identifying radon-prone areas is key to policies on the control of this environmental carcinogen. In the current paper, we present the methodology followed to delineate radon-prone areas in Spain. It combines information from indoor radon measurements with γ-radiation and geological maps. The advantage of the proposed approach is that it lessens the requirement for a high density of measurement...

On the basis of the results of the recent combined analyses of epidemiological studies, the International Commission on Radiological Protection (ICRP) revised the lifetime excess absolute risk of radoninduced lung cancer to 5 10 per working level month (WLM). When applying this new coefficient in risk assessment, it should first be understood that the coefficient is associated with a chronic ex...

OBJECTIVE Uranium miners are chronically exposed to low levels of radon and its progeny. We investigated whether radon exposure is associated with increased incidence of leukemia, lymphoma, or multiple myeloma in this population. DESIGN We conducted a retrospective case-cohort study in 23,043 uranium miners and identified a total of 177 incident cases of leukemia, lymphoma, and myeloma. Detai...
