Abstract:

In order to monitor the di usion and deposition of radioactive plume in Qinshan area after Fukushima nuclear
accident, a continuous air sampling was did from March 25 to May 6. A trace of 134Cs and 131I were detected in
the period. Results of conventional environmental radiation monitoring also showed that the specific activity of
90Sr and 137Cs in environmental samples had some abnormal changes in 2011 which almost felt back to normal
level in 2012. Although there is no abnormal change on environmental radiation level of Qinshan area till now,
the influence caused by Fukushima nuclear accident should be paid continuously attention in future by radiation
monitoring.
