Measurement Of Radon Exhalation Rate And Radiation Doses From Some Building Construction Materials
For the measurements 19 samples of building materias used in construction activities in this region of India were collected from various sites. In the present investigations radon exhalation rates from some building materials like fly ash, cement, slag, Bottom ash, Sand, Bazari, Badarpur and flooring tiles have been estimated using sealed can technique. It can be observed that Radon activity, R...
متن کاملMeasurement of radium concentration and radon exhalation rates of soil samples collected from some areas of Bulandshahr district, Uttar Pradesh, India using plastic track detectors
Background: Radon is an odourless, colourless and tasteless gas and it is the first cause of lung cancer among non- smokers. The assessment of the level of radium in building materials helps in understanding the radiological implications. It has been observed that everyone has some levels of exposure to them. Therefore measurement of radium and radon in the soil samples are important f...
متن کاملSimultaneous Measurement of Radon and Thoron Exhalation Rate from Soil and Building Materials
The mainly sources for indoor radon concentrations in all types of houses are the soil radon flux under the building (about 80%) and the radon exhalation from building materials (about20%). Our paper presents two methods for simultaneous measurement of this exhalation from soil and building materials: (1) -charcoal adsorption, respectively (2)-Lucas cell method. The both methods are applicable ...
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 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...
