Abstract: In 1975, eleven field experiments concerning the deposition of test aerosols on vegetation and other boundary surfaces were carried out in the Central Department for Radiation Protection of the Juelich Nuclear Research Center. The radioactive-labelled copper sulphate aerosols (Cu 64) produced by means of a two-fluid nozzle were present as a polydisperse spectrum and could be modified in size by changing the solution concentration and with the aid of a baffle plate. As a preliminary result it may be stated that, in the case of a mean aerosol diameter of 4 $\mu$ and a mean friction velocity of 27 cm/s, which approximately corresponds to the annual mean value to be expected, adeposition velocity of 0.1 cm/s can be considered representative for grass. Under equal test conditions, adeposition velocity of0.24 cm/s could be measured on clover, of 0.035 cm/s on vegetation-free soil, and of 0.03 cm/s on smooth aritficial surfaces.
