Abstract

Fall water, stem flow water and falling litter in a coniferous forest (C. japonica) and a broad-leaved forest (L. edulis), and rainwater on a grassland near the forests were collected, and their 7Be and 210Pb contents were measured. The average residence times of 7Be and 210Pb in the forest crowns were calculated from the balances of their radionuclides, those in the forest crown of C. japonica were 88 days for 7Be and 9.2 years for 210Pb, and those in the forest crown of L. edulis were 52 days and <1 year, respectively.
