| Abstract: | Aerosols in Nanjing air were collected by fast high flow sampling to identify radio nuclides using high-purity germanium γ spectrometer during nuclear leakage of the year 2011 in Japan. The results showed that in the aerosols samples there were very little amount of artificial radio nuclides iodine-131, cesium-137 and cesium-134 cesium which came from nuclear accident in Fukushima. The aerosols analysis indicated quantity of artificial radio nuclides in the air did not effect Nanjing environment and public health, and it needed not take any measures for protection. |
