Abstract Interception/deposition factors for airborne85Sr,131I,137Cs following atmospheric releases under simulated raining condition have been evaluated in three different type of vegetables, i.e., beans (Phaseolus vulgaries), spinach (Spinacia oleracia) and radish (Raphamus sative). The rainfall rate in the chamber was 2 mm/h (48 mm/d). Activity was injected in the form of liquid aerosols having a size distribution of 2.33 μm (AMAD) with a GSD of 1.98 μm into the experimental chamber containing the vegetable plants having an arrangement to simulate rainfall. Samples were collected soon after the 30-minute rainfall period for the evaluation of interception/deposition factor (IF/DF) of85Sr,131I,137Cs on these plants. The maximum value of the interception/deposition factor was 6.04 m3·kg−1 which was observed for131I deposition to beans plant as a whole. Interception/deposition factor values were about 4 to 7 times higher compared to dry condition for the same of aerosols and inventories. The fraction of root activity to the activity of above soil parts has also been evaluated to determine the transfer of activity to the roots.
