The activity concentration of beryllium-7 (7Be), 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. The7Be mass activity concentration on July 27 ranged from 34.8 to 147.1 Bq kg−1in herbaceous plants, from 47.6 to 116.1 Bq kg−1in subshrubs, and from 15.7 to 56.8 Bq kg−1in crop plants. The7Be mass and areal activity concentrations of a mixture of herbaceous plants increased from 66.8 to 288.7 Bq kg−1and from 0.7 to 46.5 Bq m−2, respectively, during the growing season. On an areal basis, the fraction of7Be 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 of7Be mass and areal activity concentrations in the inter-sampling intervals and the amount of precipitation.
