7Be deposition in a high-rainfall area of New Zealand

Concentrations of natural ⁷Be in air and rainwater were monitored for one year at Hokitika, New Zealand. The mean airborne concentration was 3.1±1.3 mBq m^–3, the mean Hokitika, New Zealand. The mean airborne concentration was 3.1±1.3 mBq m^–3, the mean concentration in rainwater was 2600±1200 Bq m^–3, and the mean total deposition was estimated to be 130±99 Bq m^–2 wk^–1. Most of the ⁷Be was wet deposited and the washout ratio was independent of precipitation amount. A significant linear relationship exists between the weekly wet deposition flux and weekly precipitation at this high-rainfall site.
