  Author(s): Yusoff AH, Mohamed CARYusoff AH, Mohamed CAR
  
  Sediment core samples were collected at eight stations in Peninsular Malaysia (PM) and East Malaysian (EM) harbour waters to estimate the sources of uranium deposits. The range of average activity of 234U was from 35.31 ± 4.39 Bq/kg to 67.34 ± 5.65 Bq/kg, while 238U was from 31.25 ± 4.50 Bq/kg to 81.27 ± 7.48 Bq/kg. The range of activities for 230Th and 232Th were also recorded during this study with values from 38.24 ± 3.62 Bq/kg to 150.83 ± 13.86 Bq/ kg and 28.08 ± 3.26 Bq/kg to 119.59 ± 14.58 Bq/kg, respectively. The accumulation rate of uranium in harbours were calculated using a simple box model as 0.66 x 10-3 Bq/cm2/year to 6.14 × 10-3 Bq/cm2/year and 3.98 × 10-3 Bq/cm2/year to 17.82 × 10-3 Bq/cm2..
