A SURVEY OF ENVIRONMENTAL  ̄(14)C LEVELS IN HONG KONG

Hong Kong is situated in the southern end of southeast China and is one of the most developed cities in southeast Asia. As an industrialized city, much fossil fuel is consumed annually in Hong Kong. In addition the Daya Bay nuclear power plant in Shengzhen, Guangdong Province, has just begun operation. This plant is just 20km away from Hong Kong. These factors suggest that it may be appropriate and significant to examine the variation of atmospheric  ̄(14)C levels in Hong Kong. A variety of samples, such as terrestrial annual grasses, oceanic plants and atmospheric CO_2 from different areas of Hong Kong, have been collected. The  ̄(14)C activity of them was measured and compared with that of cassia oil samples from Guangxi,China. The obtained values indicate that the environmental  ̄(14)C levels in the Hong Kong region agree with those found in Guangxi and both of them are significantly higher than the levels predicted by Povinec.
