  • The radiological impact on some workers due to the natural radionuclides from some industries

    A total of 37 different soil samples and 22 air samples were collected from natural industrial sources. The air samples were collected at a height of 1 m above the ground on 10.4 cm diameter filter paper (with a desired collection efficiency) using a high-volume air sampler. The activity concentration levels of naturally occurring radionuclides such as the U-238 series and Th-232 series were ...
