McNair Poster Presentations

Dust and soil surfaces contain terrestrial radionuclides that occur naturally in the earth's crust. However, the level of activity differs by soil type, particle size and geographic location. Some radionuclides are more abundant in one soil type but less concentrated in others. This research paper looked at the radioactivity levels of dust and soil samples based on particle size. The samples were measured in vial sample holders using HPGe Germanium detector for a period of five days each. Background radiation was counted for same amount of period and subtracted to eliminate any counting statistical errors. The results showed that there …
