| Abstract: | Artificial radioactivity level in soil of Shanghai and in Sediment of Huangpu River have been investigated during 1989 to 1990. The results showed that the levels were about the same as that in other places over China, the annual individual effective dose of 137 Cs in soil of Shanghai was estimated. |
