A Survey of Environmental 14C Levels in Hong Kong
Abstract
As an industrialized city, Hong Kong annually consumes a large amount of fossil fuel. In addition, the Daya
Bay Nuclear Power Plant in Shenzhen, Guangdong Province, has just begun operation 20 km from Hong Kong. These factors suggest that it may be appropriate and significant to examine the variation of atmospheric 14C levels in Hong Kong. We have collected and tested a variety of samples from different parts of Hong Kong; terrestrial annual grasses, marine plants and
atmospheric CO2. We measured their 14C activity and compared it with that of cassia oil samples from Guangxi Province, China. The values obtained indicate that environmental 14C levels in the Hong Kong region agree with those found in Guangxi, both of which are significantly higher than the levels predicted by Povinec, Chudy and Sivo (1986).
