Radon permeability of insulating building materials
The common presence of the radioactive nuclides in the environment cause that the whole population are exposed to radiation. The dose that is annually received by Polish population from natural sources of radiation is about 2.4 mSv per year [1]. According to the UNSCEAR 2000 Report [2], radon is the greatest contributor of exposure to natural radiation for humans. Soil and the rocks on which th...
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 کاملPermeability of Different Materials to Radon
000 The permeability of a variety of materials to ^ Rn has been measured in a Radon/Thoron Test Facility (RTTF) of the walk-in type. The measurements were conducted using an automated multi-sensor apparatus consisting of a number of ^Rn passive monitors and meteorological sensors which permit simultaneous permeability studies of up to 12 different materials. Twenty-two different materials were ...
متن کاملApplicability of various insulating materials for radon barriers.
The effectiveness of various insulating materials for limiting radon entry into houses has been investigated under laboratory conditions. Results for the radon diffusion coefficient measurements in more than 80 insulating materials are summarized. We have discovered that great differences exist in diffusion properties, because the diffusion coefficient varies within four orders from 10(-13) m2/...
متن کاملRadon exhalation from building materials for decorative use.
Long-term exposure to radon increases the risk of developing lung cancer. There is considerable public concern about radon exhalation from building materials and the contribution to indoor radon levels. To address this concern, radon exhalation rates were determined for 53 different samples of drywall, tile and granite available on the Canadian market for interior home decoration. The radon exh...
