Radiological impact assessment of TE-NORM generating from combustion of fuel in thermal power plant using RESRAD model

الملخص EN

Industrial practices involving natural resources often concentrate radionuclides to a degree that may pose a risk to humans and the environment.

in this study natural radioactive materials TE-NORM are generated from the combustion of natural gas and fuel oil in a typical thermal power plant in Egypt.

they were accumulated in the form of sludge or scales inside pipes, separators, heaters, storage tanks, and any other plant equipment or deposited in the soil surface land of the thermal power plant.

the average measurements of the radioactivity of radionuclides in the contaminated soil of the thermal power plant were used as input data for the RESRAD computer code to estimate the radiological doses and health risks to the workers.

in this assessment, the exposure source parameters were adjusted for a period of 100 years.

the predicted maximum total effective doses equivalent (TEDE) for external exposure and soil ingestion of the contaminated area received by workers were (17.4 and 0.106 πsv / y), also their annual total cancer risk for external exposure and soil ingestion was 2.9 x 10-5 and 2.68 x 10-8 respectively.

it is found that the estimated doses and risks received by workers were below the international limits.
