Radionuclides can be released into the terrestrial environment from nuclear facilities through particulate matter or gases. Radionuclide deposition in flora and soil is the initial step in their transfer into the terrestrial environment and food chain. Two main depositional processes remove pollutants from the atmosphere. Wet deposition refers to the transfer of a substance from the atmosphere to the ground in snow, hail, or rain. Dry deposition refers to the direct transport of gases and particulate matter to and absorption by natural surfaces such as vegetation.
The percentage of radionuclides that are first retained by vegetation is referred to as interception, and it is defined as the portion of radionuclides that are deposited by both wet and dry deposition. In any radioecological model, the fraction of radionuclides initially intercepted is a very substantial quantity, although the retained radionuclides are eventually weathered into the soil. This is because direct deposition might result in relatively high radioactive quantities in feed and meals. In this paper, a review of various mathematical models in understanding the processes involved in the transport of radionuclides following foliar uptake by plants is studied. However, in Estimating the concentration of radionuclides in food and assessing doses in humans, the systemic transport of radionuclides is critical as this is especially important for plants where only certain parts are used as food or feed, such as cereals and potatoes.
