The work reported here deals with the study of interception/deposition and translocation of ⁸⁵Sr, ¹³¹I, and¹³⁷ Cs in three different types of vegetables i.e. beans (Phasoolus vulgaris), spinach (Spinicia olericia) and radish (Raphanous sative) following redionuclides release to the environment. Activity was injected in the experimental chamber in the form of aerosols having a size distribution of 0.3–1.0 µm (AMAD). Plant samples were collected soon after the injection for the evaluation of interception/deposition factors (IF/DF) for the different parts of the plants, as well as for the whole plant and the washable fraction of the deposited activity and its variation with time. The evaluated IF/DF shows a minimum value of 0.12 m³ kg⁻¹ for ⁸⁵Sr in case of spinach whole plant and maximum value of 1.93 m³ kg⁻¹ for ¹³¹I in case of beans whole plant. Translocation factors (TF) have also been evaluated for the activity that migrates from the above soil plant parts to the root and its variation with time. The evaluated TF shows a range of 7.27 × 10⁻³ to 136 × 10⁻³.
