某污染区含钚再悬浮气溶胶的粒度特征

Abstract

Abstract: Soil and fractioned aerosol samples were collected at some contaminated areas, and the ²³⁹Pucontent was determined. The size distribution characteristics of plutonium in the resuspended aerosol were analyzed. The results show that the average value of activity median aerodynamic diameter of plutonium is 3.1 μm under undisturbed conditions and increased to 12 μm under disturbed conditions. The typical size distribution patterns of plutonium are consistent with ¹³⁷Cs size distribution patterns proposed by other researchers. The enrichment factors were found to be 0.002—0.2 and showed no obvious relationship with diameters. Also, taking the mechanism of wind erosion of soil into consideration, the process of radionuclide resuspension is discussed.

Key words: resuspension, aerosol, plutonium, size distribution
