| 英文摘要 | The activity concentration of beryllium-7 ((7)Be), a naturally occurring cosmogenic radionuclide produced in the upper atmosphere, was measured in plants on the Loess plateau of China during the growing season of 2005. The (7)Be mass activity concentration on July 27 ranged from 34.8 to 147.1 Bq kg(-1) in herbaceous plants, from 47.6 to 116.1 Bq kg(-1) in subshrubs, and from 15.7 to 56.8 Bq kg(-1) in crop plants. The (7)Be mass and areal activity concentrations of a mixture of herbaceous plants increased from 66.8 to 288.7 Bq kg(-1) and from 0.7 to 46.5 Bq m(-2), respectively, during the growing season. On an areal basis, the fraction of (7)Be in plants in the soil-plant system increased from 0.4 to 8.4% during the growing season. Positive linear correlations were found between the increases of (7)Be mass and areal activity concentrations in the inter-sampling intervals and the amount of precipitation. |
