Abstract

Analysis levels of 210Po and 210Pb were determined in the edible tissue of sea bass (Lates calcarifer) from 14 cages in the west and east coast Peninsular of Malaysia. The concentrations level in fish were found varies from 1.35 ± 0.22 to 6.20 ± 0.99 Bq/kg dry weight 210Po and 3.30 ± 2.69 to 51.71 ± 19.26 Bq/kg dry weight 210Pb. The level of this radionuclide was much related to the anthropogenic activities at the sampling locations neighbouring area, differences in metabolisms of fish and food intake pattern for each cage. Then the calculated daily intake value due to fish consumption was to be 7.69 mBq/d/person 210Po and 35.90 mBq/d/person 210Pb, which lower than those reported in others countries. In addition, the collective doses of 210Po and 210Pb were estimated to be 0.001mSv/year and 0.009 mSv/year, respectively. This suggests that the dose received by Malaysian due to consumption of fish is rather small, and did not deteriorate human's health and safe for consumption.
