Radium and radon exhalation studies of soil
Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...
متن کاملRadon permeability and radon exhalation of building materials.
High radon concentrations indoors usually depend on the possibilities of radon penetration from the surrounding soil into the buildings. Radon concentrations in dwellings up to 100 kBq/m3 were found in some special regions (i.e. Schneeberg/Saxony, Umhausen/Tyrol), where the soil shows a high uranium content and additionally, a fast radon transport in the soil is possible. To reduce the radon ex...
متن کاملRadon exhalation rates from stone and soil samples of Aravali hills in India
Background: The most popular building materials are soil bricks and different types of stones. Radon is released into ambient air from soil and stones due to ubiquitous uranium and radium in them, thus increasing the airborne radon concentration. The radioactivity in soils is related to radioactivity in the rocks from which the soil is formed. In the present investigation, the radon em...
متن کاملRadon Diffusion Coefficient in Radon-proof Membranes Determination and Applicability for the Design of Radon Barriers
The selection of effective radon-proof insulation from the total amount of tanking materials is very difficult due to the lack of information about radon diffusion through these materials and the absence of general guidelines for the design of radon barriers. This report describes a method for radon diffusion coefficients determination used in the Czech Republic. Results of radon diffusion coef...
