RADIONUCLIDES AND WIND EROSION
Öz
Wind erosion is effective on 500 million ha of land in arid and semi-arid regions where annual precipitation is less than 500 mm such as Aralik-Igdir, Turkey; whereas, both naturally and artificially radionuclides are almost spread over the whole earth. Humankind inevitably encountered radionuclides in July, 1945 when nuclear era started by tentatively making burst a blast in New Mexico, USA. Creep, saltation, and suspension are three different effects of wind erosion on soils. Quite small particles (<100 µm) are transported over a great distance and kept aloft for a long time. Radionuclides are also moved and carried away as soil-bonded ones and radioactive aerosols due to wind erosion caused by strong winds. This fact is evaluated as different by each science. Some radionuclide movements are an important method for exploring soil redistribution by wind due to their strongly adsorbing to soil particles. Although 137Cs is the most commonly preferred anthropogenic radioisotope used to assess soil redistribution rates, 239+240Pu has been recently started to be used as a tracer. I want to emphasize that wind erosion area of Aralik-Igdir, Turkey is waiting to be explored.
