Radionuclide monitoring of some place in Xinjiang after the Fukushima nuclear accident

On a April to 19 May 2011, collected 36 aerosol samples; March 30th collected a sample of radioactive xenon in the air; April 5th collected a sample of snow water. Measured and obtained activity concentration of 131I, 134Cs, 137Cs, 133Xe and natural 7Be by using ultra-low background HPGe γ spectrometer system. Monitored and found some radionuclides which spread to release somewhere in Xinjiang in China after Fukushima nuclear accident, including 131I, 134Cs, 137Cs and 133Xe, 131I, 134Cs and 137Cs, on April 6, their radiation levels reach maximum, and their activity concentration were respectively were respectively 0.95, 0.25 and 0.24 mBq/m3; the activity concentration of 133Xe in air samples was 100 mBq/m3; and the activity concentration of 131I, 134Cs and 137Cs in snow water samples were respectively 240, 19, 23 mBq/L. The monitoring results provide the basic data for the study the influence of radionuclides in Fukushima nuclear accident on the global. (authors)
