Effect of Moisture and Additive on Radon Exhalation Rate from Concrete
Building materials are significant contributor of indoor radon after the soil. The indoor radon level depends upon the radon flux coming out from wall, ceiling and roofs of the dwellings. The radon flux from the wall that in most cases is concrete depends upon many factors like radium content, porosity, moisture, composition of mix design for construction of concrete and age of concrete. The pr...
متن کاملThe effective radium content and radon exhalation rate in hair dyes samples
Background: Hair dyes are the important materials widely used by various peoples in Iraq and other countries. The present work investigates the presence of the effective radium content and radon exhalation rate in hair dyes samples. Materials and Methods: Twenty hair dyes samples were collected from Iraqi markets. Sealed can technique using LR-115 type II plastic track detector s ha...
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 کاملThe Influence of Meteorological and Soil Parameters on Radon Exhalation
To clarify the mechanism of radon transport from soil to surface, long term continuous measurements of radon exhalation were conducted at one site in combination with measurements of radon concentration in soil gas, soil temperature, pressure difference, soil moisture and meteorological parameters. Based on the results of measurements over a two year period, the influence of meteorological and ...
متن کاملRadium 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...
