Particulate Matter (PM) analysis by combining gamma spectroscopy and environmental factors.

In order to trace the origin of Particulate Matter (PM) in Korea, the research was conducted to analyze the nuclide of PM samples. To analyze the PM sample, we performed Backtracking Analysis and Gamma spectroscopy. PM is affected by the size of the atmospheric mixing layer height and the air flow according to the air mass. The air flow of the 2 seasons (summer and autumn) was predicted by using Hysplit (backtracking analysis). And the radioactivity of nuclides in the PM sample collected from the measuring site is confirmed using gamma spectroscopy and radioactivity calculation method. Takuya (J Nuclear Radiochem Sci, 8(1):5–9, 2007) As a result of analyzing samples collected in 2 seasons, it was confirmed that the radioactivity of specific nuclides changed according to the season and was affected by air flow. In conclusion, the origin of PM can be estimated by confirming the change in PM and nuclides. [ABSTRACT FROM AUTHOR]
