Influence of Radioactive Contamination to Agricultural Products Due to Dry and Wet Deposition Processes During a Nuclear Emergency
Hwang, Won-Tae;Kim, Eun-Han;Suh, Kyung-Suk;Han, Moon-Hee;Choi, Pong-Ho;Lee, Chang-Woo;
Combined with deposition model onto the ground of radionuclides, the influence of radioactive contamination to agricultural products was analyzed due to wet deposition as well as dry deposition from radioactive air concentration during a nuclear emergency. The previous dynamic food chain model, in which initial input parameter is only radionuclide concentrations on the ground, was improved for the evaluating of radioactive contamination to agricultural products from either radionuclide concentrations in air or radionuclide concentrations on the ground. As the results, in case of deposition onto the ground, wet deposition was more dominant process than thy deposition. While the contamination levels of agricultural products were dependent on the a variety of factors such as radionuclides and rainfall rate. It means that the contamination levels of agricultural products are determined from which is more dominant process between deposition on the ground and interception onto agricultural plants.
