| 内容記述 | Surface sediment samples were collected at 31 stations in the east and west coasts of Peninsular Malaysia on August 2003 and February 2004, respectively for determine the level of natural radium isotopes. The concentration levels of 228Ra and 226Ra varied at east coast of Peninsular Malaysia with ranging from 64 to 145 Bqkg(-1) dry and 22 to 124 Bqkg(-1) dry, respectively. Meanwhile, in the west coast stations were ranging from 35 to 65 Bqkg(-1) dry for 228Ra and 22 to 36 Bqkg(-1) dry for 226Ra. The statistical analysis with an ANOVA at 95% confidence level was also proved that the concentration level of radium at sampling stations was different between east and west coast regions. These probably related to the sources of radium which is discharge from the neighboring countries and western Pacific region during monsoon seasons. The distribution ratios of 228Ra/226Ra were slightly higher than the natural value and fluctuated in the east and west coasts of Peninsular Malaysia with an average about 1.8. | |||||
