ESTIMATION OF RADIOLOGICAL DOSES OVER TURKEY BY USING ATMOSPHERIC DISPERSION MODEL AFTER FUKUSHIMA NUCLEAR POWER PLANT ACCIDENT

The effects of Fukushima Nuclear Power Plant accident over Anatolian Peninsula were investigated by using an atmospheric dispersion model with three different source terms. Air concentration amounts for 131I particles over Turkey were found between 0.1 mBqm-3 and 0.5 mBqm-3, for 137Cs between 0.01 mBq m-3 and 0.05 mBqm-3, and for 131I gas between 1 mBqm-3 and 10 mBqm-3. Results were compared with the measured values. The radiological doses were calculated over Anatolian Peninsula by using air concentration values simulated by atmospheric model. In addition the effective doses were found around nSv which shows that Fukushima Nuclear Power Plant accident has limited effects compared to Chernobyl Power Plant accident
