This paper presents a compartmental model for estimating the ingestion dose, due to 137Cs, arising from the consumption of marine fish in Hong Kong. 137Cs is one of the more important radionuclides released in routine liquid effluents discharged from the Guangdong Nuclear Power Station at Daya Bay, which began commercial operation in 1994. In the model,(More)
Caesium-137 is one of the more important radionuclides released during a nuclear power plant accident. Based on a mathematical model developed earlier by the present authors for estimating 137Cs ingestion dose from consumption of marine fish in Hong Kong, doses due to an accidental release into Daya Bay from the Guangdong Nuclear Power Station are(More)
This paper describes the adaptation work carried out on the radioecological model ECOSYS for radionuclide transfer in the Hong Kong ecological environment. The adapted model predicts that the ingestion dose due to dry deposition in Hong Kong shows less pronounced seasonal dependence than that in Germany. This is mainly attributed to differences in climate,(More)
Based on a model developed specifically for the local freshwater fish culture system, a dose transfer coefficient for 137Cs of 1.15 mSv per MBq m(-2) is obtained for the consumption of freshwater fish in the first year after deposition. Several countermeasures are suggested to reduce the ingestion dose resulting from a nuclear accident. These(More)
