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 کاملMeasurement of Radon Concentrations and Surface Exhalation Rates using CR-39 detector in Soil Samples of Al-Diwaniyah Governorate, Iraq
Introduction: Natural radioactivity in the soil is considered a major indicator of radiological contamination. Primordial radionuclides are the main source of natural radioactivity. Natural radioactivity transfers radionuclides into the environment and poses radiation hazards to people's health. Therefore, the present study aimed to determine the radon concentration an...
متن کاملEstimation of Radon Exhalation Rate and Radium Content in Soil Samples of Pathankot District, Punjab Using LR-115 Plastic Detector
In the present investigation, soil samples were collected from 10 villages belonging to Pathankot district, Punjab, India and assessed for radium content using LR-115 plastic detector. The ‘track etch’ technique has been employed for measuring the radium content. From the radium content, radon exhalation rates and mass exhalation rates were calculated for these samples. The mass exhalation rate...
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 کاملMeasurement 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...
