Radiocesium activity in turkish tea followed the Chernobly after thirteen years

The aim of the study is to investigate the distribution of ''1''3''7Cs activity levels in Turkish tea widely consumed in the Country in 2000. The results obtained from gamma radiometric measurements were shown that the avarage radiocesium level in marketing tea was 72 Bq/kg. The accident in April 1986 at the Chernobyl Nuclear Power Station in the former Union of Soviet Socialist Republics in which large amounts of radioactive materials were released into the environment was the most serious ever to have occured in connection with the use of nuclear energy to generate electricity. Changing mateorological conditions during the active phase of accident with winds from different directions at various altitutes and continuing releases over a ten day period, resulted in a very complex dispersion pattern. After the accident at chernobyl, large areas in northern Turkey were heavily contaminated with radiocesium by wet deposition in early May 1986. During this emergency, Cekmece Nuclear Research and Traing Center performed analyses of various substances, including foodstuffs to asses population risk
