ABSTRACT
Objective To investigate the environmental impact of the Japanese Fukushima No.1 nuclear power plant accident on radiation levels in some areas of Liaoning province.Methods The emergent monitoring was performed by detecting atmosphere aerosols,precipitations,drinking water,vegetables,milk and seafood by gamma spectrometry analysis and gross activity measurements.Results The fission radionuclides of 131I,134Cs and 137Cs were detected in atmosphere aerosols 20 d after nuclear accident.The rad ionuclides of 131I,134Cs and 137Cs were found existing in atmosphere for 25,4 and 6 d,respectively,with the highest concentrations of 4.6 × 10 3,2.9 × 10-4 and 4.2 × 10-4 Bq/m3,respectively.The man-made fission radionuclides could not be detected in vegetablcs,drinking water and milk from Shenyang city and seafood from Dandong city.Conclusions The atmosphere might be slightly contaminated in Liaoning province due to the nuclear accident,whereas the vegetables,milk and drinking water not contaminated.
