Description 416-422
The bulk of bricks made worldwide are burnt clay bricks, and this volume of manufacture requires 230 - 242 million m3
of agricultural land. This corresponds to 25,500 hectares of rich farmland at a depth of 1 meter. This type of exploitation will
have a substantial detrimental impact on national food security. According to the present need, efficient use of industrial
waste, such as fly ash, is necessary. So it becomes very important to limit the removal of top soil to build bricks and to
encourage the use of pulverized fly ash (PFA) instead. So it is essential to examine the levels of radioactivity from natural
sources and the amount at which radon is exhaled from building materials to manage the exposure of occupants to natural
radiation. The radioactivity concentration of nuclides is determined using a high-resolution sodium iodide with a thallium
activator gamma spectrometer. Radon exhalation rates were examined in the exhalation chamber using a hermetically
shaped container and observing the activity over time. The focus of this research is to examine the radioactive concentration
levels of radium, thorium, and potassium, as well as radon exhalation rates of Clay-Pulverized Fly Ash bricks mixed in
different proportions. All radiation hazard factors linked with the radioactive nuclide and radon exhalation rates of clay
pulverized fly ash bricks are examined and compared to the recommended limits from the United Nations Scientific
Committee on the Effects of Atomic Radiation (UNSCEAR) data.
