Measurements of Indoor Radon Levels in India using Solid~State Nuclear Track Detectors: Need for Standardisation
Solid-state nuclear track detectors are being used to obtain the time integrated concentration levels of indoor radon/thoron and their daughters. This technique is preferred for taking such measurements in dwellings Such measurements are important as the radiation dose to human beings due to indoor radon constitutes more than 50 per cent of the total dose including that received from the natura...
متن کاملIndoor radon measurements in residential dwellings in Qom, Iran
Background: Inhalation of radon and its short-lived decay products is one of the ‎most significant sources of exposure to natural radiation. Radon is the second cause ‎of lung cancer in the populations. The present study was carried out under the projects of ‎national radon, with the aim of determining the concentration of indoor in the city of Qom ‎located in the central se...
متن کاملLong-term measurements of unattached radon progeny concentrations using solid-state nuclear track detectors.
We described a method for long-term passive measurements of unattached fraction fp of the potential alpha energy concentration of radon progeny from a set of measured (f1, f2, f3) values, where fi=Ci/C0 (i=1, 2, 3), and C0, C1, C2 and C3 were the concentrations of 222Rn, and the airborne concentrations of 218Po, 214Pb and 214Bi, respectively. Jacobi room model parameters were randomly sampled f...
متن کاملIndoor exposure assessment of radon in the elementary schools, Palestine
Background: Many public health agencies rank residential radon exposure as the second leading cause of lung cancer after cigarette smoking. It has been shown that the risk coefficient for lung cancer is higher for children than that for adults. Therefore, indoor radon measurements were carried out in the elementary schools of Tulkarem province, West Bank, Palestine. Materials and Methods: Two h...
متن کاملIndoor Radon Measurements in Argentina
Rn is the most important source of natural radiation and is responsible for approximately half of the received dose of the totality of the sources. Most of this dose comes from the inhalation of the progeny of Rn, and this happens especially in closed atmospheres. Due to this, the control of the levels of Rn concentration in the different geographic areas is important where human activities are...
