Assessment of Natural Radionuclides Content and Radon Exhalation of Clay Pulverized Fly Ash Bricks

The bulk of bricks made worldwide are burnt clay bricks, and this volume manufacture requires 230 - 242 million m3 agricultural land. This corresponds to 25,500 hectares rich farmland at a depth 1 meter. type exploitation will have substantial detrimental impact on national food security. According the present need, efficient use industrial waste, such as fly ash, is necessary. So it becomes very important limit removal top soil build encourage pulverized ash (PFA) instead. essential examine levels radioactivity from natural sources amount which radon exhaled building materials manage exposure occupants radiation. concentration nuclides determined using high-resolution sodium iodide with thallium activator gamma spectrometer. Radon exhalation rates were examined in chamber hermetically shaped container observing activity over time. focus research radioactive radium, thorium, potassium, well Clay-Pulverized Fly Ash mixed different proportions. All radiation hazard factors linked nuclide compared recommended limits United Nations Scientific Committee Effects Atomic Radiation (UNSCEAR) data.
